Drop Down List
The process of attaching the “dropdownlist” control to a source of data is nothing but “data binding.” This process of “binding” can occur in several ways including databases, arrays, and so on.
Binding to a Simple Array
Binding to an ArrayList
Binding to a hashtable
Binding to a data table
Binding to a data set
Binding to a data view
Binding to a set of objects
Binding manually

postback
Definition of "postback?" ?
Basically all the information of a webpage is sent back to the server for reprocessing.
Source(s):
http://en.wikipedia.org/wiki/Postback
When you buy a plane ticket on the internet, you fill in your name, credit card number, etc and choose a flight.
When you click 'Submit' button, the information you typed and choices you made are "posted back" to the mothership - i.e. the web server - so that they can reserve your seat and take your money - hence the term "postback".
How To Ask Questions The Smart Way
Use meaningful, specific subject headers
On mailing lists, newsgroups or Web forums, the subject header is your golden opportunity to attract qualified experts' attention in around 50 characters or fewer. Don't waste it on babble like “Please help me” (let alone “PLEASE HELP ME!!!!”; messages with subjects like that get discarded by reflex). Don't try to impress us with the depth of your anguish; use the space for a super-concise problem description instead.
One good convention for subject headers, used by many tech support organizations, is “object - deviation”. The “object” part specifies what thing or group of things is having a problem, and the “deviation” part describes the deviation from expected behavior.

Write in clear, grammatical, correctly-spelled language
If you are writing in English but it is a second language for you, it is good form to alert potential respondants to potential language difficulties and options for getting around them. Examples:
English is not my native language; please excuse typing errors.
If you speak $LANGUAGE, please email/PM me; I may need assistance translating my question.
I am familiar with the technical terms, but some slang expressions and idioms are difficult for me.
I've posted my question in $LANGUAGE and English. I'll be glad to translate responses, if you only use one or the other.

Stupid:
How do I get the color-picker on the FooDraw program to take a hexadecimal RGB value?
Smart:
I'm trying to replace the color table on an image with values of my choosing. Right now the only way I can see to do this is by editing each table slot, but I can't get FooDraw's color picker to take a hexadecimal RGB value.

Questions Not To Ask
Q:
Where can I find program or resource X?
A:
The same place I'd find it, fool — at the other end of a web search. Ghod, doesn't everybody know how to use Google yet?
Q:
How can I use X to do Y?
A:
If what you want is to do Y, you should ask that question without pre-supposing the use of a method that may not be appropriate. Questions of this form often indicate a person who is not merely ignorant about X, but confused about what problem Y they are solving and too fixated on the details of their particular situation. It is generally best to ignore such people until they define their problem better.
Q:
How can I configure my shell prompt?
A:
If you're smart enough to ask this question, you're smart enough to RTFM and find out yourself.
Q:
Can I convert an AcmeCorp document into a TeX file using the Bass-o-matic file converter?
A:
Try it and see. If you did that, you'd (a) learn the answer, and (b) stop wasting my time.
Q:
My {program, configuration, SQL statement} doesn't work
A:
This is not a question, and I'm not interested in playing Twenty Questions to pry your actual question out of you — I have better things to do. On seeing something like this, my reaction is normally of one of the following:
do you have anything else to add to that?
oh, that's too bad, I hope you get it fixed.
and this has exactly what to do with me?
Q:
I'm having problems with my Windows machine. Can you help?
A:
Yes. Throw out that Microsoft trash and install an open-source operating system like Linux or BSD.
Note: you can ask questions related to Windows machines if they are about a program that does have an official Windows build, or interacts with Windows machines (i.e., Samba). Just don't be surprised by the reply that the problem is with Windows and not the program, because Windows is so broken in general that this is very often the case.
Q:
My program doesn't work. I think system facility X is broken.
A:
While it is possible that you are the first person to notice an obvious deficiency in system calls and libraries heavily used by hundreds or thousands of people, it is rather more likely that you are utterly clueless. Extraordinary claims require extraordinary evidence; when you make a claim like this one, you must back it up with clear and exhaustive documentation of the failure case.
Q:
I'm having problems installing Linux or X. Can you help?
A:
No. I'd need hands-on access to your machine to troubleshoot this. Go ask your local Linux user group for hands-on help. (You can find a list of user groups here.)
Note: questions about installing Linux may be appropriate if you're on a forum or mailing list about a particular distribution, and the problem is with that distro; or on local user groups forums. In this case, be sure to describe the exact details of the failure. But do careful searching first, with "linux" and all suspicious pieces of hardware.
Q:
How can I crack root/steal channel-ops privileges/read someone's e-mail?
A:
You're a lowlife for wanting to do such things and a moron for asking a hacker to help you.

Good and Bad Questions
Finally, I'm going to illustrate how to ask questions in a smart way by example; pairs of questions about the same problem, one asked in a stupid way and one in a smart way.
Stupid: Where can I find out stuff about the Foonly Flurbamatic?
This question just begs for "STFW" as a reply.
Smart: I used Google to try to find “Foonly Flurbamatic 2600” on the Web, but I got no useful hits. Can I get a pointer to programming information on this device?
This one has already STFWed, and sounds like he might have a real problem.
Stupid: I can't get the code from project foo to compile. Why is it broken?
The querent assumes that somebody else screwed up. Arrogant git...
Smart: The code from project foo doesn't compile under Nulix version 6.2. I've read the FAQ, but it doesn't have anything in it about Nulix-related problems. Here's a transcript of my compilation attempt; is it something I did?
The querent has specified the environment, read the FAQ, is showing the error, and is not assuming his problems are someone else's fault. This one might be worth some attention.
Stupid: I'm having problems with my motherboard. Can anybody help?
J. Random Hacker's response to this is likely to be “Right. Do you need burping and diapering, too?” followed by a punch of the delete key.
Smart: I tried X, Y, and Z on the S2464 motherboard. When that didn't work, I tried A, B, and C. Note the curious symptom when I tried C. Obviously the florbish is grommicking, but the results aren't what one might expect. What are the usual causes of grommicking on Athlon MP motherboards? Anybody got ideas for more tests I can run to pin down the problem?
This person, on the other hand, seems worthy of an answer. He/she has exhibited problem-solving intelligence rather than passively waiting for an answer to drop from on high.
In the last question, notice the subtle but important difference between demanding “Give me an answer” and “Please help me figure out what additional diagnostics I can run to achieve enlightenment.”

Computer engineering
Computer System engineering, also called computer engineering, is a discipline that integrates several fields of electrical engineering and computer science required to develop computer systems. Computer System engineers usually have training in electronic engineering, software design and hardware-software integration instead of only software engineering or electronic engineering. Computer System engineers are involved in many hardware and software aspects of computing, from the design of individual microprocessors, personal computers, and supercomputers, to circuit design. This field of engineering not only focuses on how computer systems themselves work, but also how they integrate into the larger picture.
In many institutions, computer engineering students are allowed to choose areas of in-depth study in their junior and senior year, because the full breadth of knowledge used in the design and application of computers is beyond the scope of an undergraduate degree. The joint IEEE/ACM Curriculum Guidelines for Undergraduate Degree Programs in Computer Engineering defines the core knowledge areas of computer engineering as the following:
1. Digital and Logic Design (Using Verilog or VHDL)
2. Algorithms and Compiler Construction
3. Computer architecture and organization
4. Industrial Instrumentation
5. Industrial automation (Using PLCs,PLDs,and HMI)
6. Robotics
7. Artificial intelligence
8. Circuit analysis
9. Signal and systems
10. Database systems (Using MS Access, SQL and Oracle)
11. Digital (Computer) electronics
12. Digital signal processing (Using Matlab)
13. Electronics
14. Embedded systems (Using Microcontrollers,FPGA,PLDs and ARMs)
15. Human-computer interaction or Human Machine Interface(HMI)
16. Interactive Systems engineering
17. Operating systems (Using LINUX,SOLARIS,Mac OS and RTOs)
18. Programming fundamentals
19. Social and professional issues
20. Software engineering (Using UML)
21. Computer security
22. VLSI design and fabrication
23. Computer networking (Using Omnet,Opnet,RouterSim and Packet Tracer)
24. Wireless Communication (Using Zigbee,Bluetooth,WiFi and WiMAX)
25. Fault diagnostic and tolerant systems
26. Parallel and distributed computing
27. Control engineering (Digital and Analog)
28. Microprocessors interfacing and programming
29. Microwave Engineering
30. Electric and Electronic Machines
31. Power Electronics
32. Process Control and Instrumentation
33. Programming Languages (Using C)#,VB.NET,JAVA)
34. Computer Graphics (Using 3DS MAX,MAYA)
35. Data Acquisition Systems
36. Internet and Web Programming (Using XHTML,ASP.NET,JAVASCRIPT AND COLD
37. FUSION)
38. Hardware Engineering (PC Components Design LAN Card,Sound Card,VGA
39. Card,Motherboard,MODEM etc)
40. PC Interfacing and Process Control
41. Analog and Digital PCB Design (Using ORCAD,ARES,EAGLEVIEW)
The breadth of disciplines studied in computer engineering is not limited to the above subjects, but can include any subject found in engineering.

* The target attribute is designed to be a general hook for binding to an external environment (such as Frames, multiple windows, browser-tabbed windows); when there is no such external environment bound to the user agent, the user agent can ignore the target attribute. When there is an external environment bound, the conformance requirements for the target attribute are defined in each environment.
* The content author needs to be aware that the user agent behavior for the target attribute depends on multiple factors such as the existence of an environment binding, restrictions of available resources, existence of other applications and user preferences (such as pop-up blockers), and implemententation-dependent design decisions. When there is no external environmental conformance, it is recommended that authors do not depend on use of the target attribute.
* It should be noted that any implementation-dependent use of the target attribute might impede interoperability.

Search engine optimization - SEO
Images: Use the alt attribute to provide descriptive text. In addition, we recommend using a human-readable caption and descriptive text around the image.
Javascript: Place the same content from the Javascript in a no script tag. If you use this method, ensure the contents are exactly same as what is contained in the Javascript and that this content is shown to visitors who do not have Javascript enabled in their browser.
Videos: Include descriptive text about the video in HTML. You might also consider providing transcripts.
< src = "puppy.jpg" alt= "">
Better:
< img src="puppy.jpg" alt="puppy">
Best:
< src="puppy.jpg" alt="Dalmatian puppy playing fetch">

Best:
< src="puppy.jpg" alt="Dalmatian puppy playing fetch">
Tip:
The alt attribute is meant to be used as an alternative text if the image is not available, not as a mouse-over text. To show a mouse-over text on images or image-maps, use the title attribute, like this:
< img src="angry.gif" alt="Angry face" title="Angry face" />
To be avoided
< src="puppy.jpg" alt="puppy dog baby dog pup pups puppies doggies pups litter puppies dog retriever labrador wolfhound setter pointer puppy jack russell terrier puppies dog food cheap dogfood puppy food">

The .NET Framework
Microsoft introduced the .NET Framework in 2000 as a new approach to software development. The .NET Framework borrowed ideas from the best practices in the software industry as well as brought new ideas to the table in an effort to meet developer needs and requests.
Virtually all programming languages manage data at some point. The primary reason that communication between applications created using C++, Visual Basic, Visual FoxPro, and other languages was difficult was because each language stored data being managed in a unique set of data types. For example, an integer in one language may not represent an integer in another language. Data needed to be converted to common data types to communicate between languages.
The .NET Framework introduced a common set of data types (the Common Type System) that is used by all .NET-compliant languages (C++, Visual Basic, C#, etc). Thus all languages can easily intercommunicate. Furthermore, all .NET-compliant languages render a common result when compiling code, Microsoft Intermediate Language (MSIL). (see footnote) MSIL can be deployed to any platform running the Common Language Runtime (CLR). Currently, the CLR is only available for Microsoft Windows although an open source version of the CLR was created for Linux (called the Mono Project). Code written by using the .NET Framework is compiled instead of interpreted resulting in much better performance than Java and competing technologies.
Microsoft took the Web development industry by storm with their .NET upgrade to ASP. ASP.NET put a new face on Web development through a compiled code architecture and improved state management and it provides access to the full functionality of the .NET Framework. ASP.NET is built around XML, supports the latest Web development standards, and allows for the creation of advanced Web Services.
The .NET Framework also provides improved data access and database integration through ADO.NET. For more information, see MSDN.
There are many more features and benefits of the .NET Framework than those mentioned here. The .NET Framework has become the leading software development environment available.

ASP.NET AJAX
ASP.NET AJAX was developed to improve performance in the browser by making post backs and calls between the browser and server asynchronously. ASP.NET AJAX uses new built-in types and controls and JavaScript.
Both ASP.NET and ASP.NET AJAX are heavily dependent upon the ASP.NET page event life cycle, are tightly coupled to the server, and have a tough time competing with advanced, media-rich plug-in solutions such as Adobe Flash. Additionally, it is difficult to create Web applications that offer a consistent experience across all supported browsers and platforms by using ASP.NET and AJAX. In 2006, Microsoft began developing a solution to extend into the browser and offer media experiences more robust than competing plug-in solutions.
In 2007, Microsoft introduced Silverlight. (see footnote) Silverlight is a free plug-in that encompasses a subset of functionality from the .NET Framework and WPF. In a manner similar to the JVM (see footnote), Silverlight runs in the browser as a "sandbox" - a secure zone installed into the browser that accommodates Silverlight functionality while completely protecting the host platform from any possibly adverse actions performed by Silverlight.

The .NET Framework can also be fully extended by developers to create custom classes and types. The functionality of the .NET Framework spans the server, the workstation, and the Web. The four primary additions to the .NET Framework as of version 3.0 are:
Windows Communication Foundation (WCF)
Windows Workflow Foundation (WF)
CardSpace
Windows Presentation Foundation (WPF)
WPF is used to develop elaborate user interfaces like those that adorn Windows Vista and managed advanced media streaming and integration. WPF is the a complete revamp of Windows Forms so that user interface, graphic, and media development is now designed around the .NET Framework.Windows Communication Foundation (WCF)
WCF encompasses the ASP.NET Web Services and .NET remoting functionality that was contained in the .NET Framework 2.0 as well as new communication technologies.Windows Workflow Foundation (WF)
WF is used to model complex workflow processes.CardSpace
CardSpace is the embodiment of new security and user authorization functionality.
I Just Died In Your Arms Tonight
Oh I, I just died in your arms tonight
It must have been something you said
I just died in your arms tonight
I keep looking for something I can't get
Broken hearts lie all around me
And I don't see an easy way to get out of this
Her diary it sits on the bedside table
The curtains are closed, the cats in the cradle
Who would've thought that a boy like me could come to this
Oh I, I just died in your arms tonight
It must've been something you said
I just died in your arms tonight
Oh I, I just died in your arms tonight
It must've been some kind of kiss
I should've walked away, I should've walked away
Is there any just cause for feeling like this?
On the surface I'm a name on a list
I try to be discreet, but then blow it again
I've lost and found, it's my final mistake
She's loving by proxy, no give and all take
'cos I've been thrilled to fantasy one too many times
Oh I, I just died in your arms tonight
It must've been something you said
I just died in your arms tonight
Oh I, I just died in your arms tonight
It must've been some kind of kiss
I should've walked away, I should've walked away
It was a long hot night
And she made it easy, she made it feel right
But now it's over, the moment has gone
I followed my hands not my head, I know I was wrong
Oh I, I just died in your arms tonight,
It must've been something you said,
I just died in your arms tonight

It must've been some kind of kiss
I should've walked away, I should've walked away

Unicode
Unicode provides a unique number for every character,
no matter what the platform,
no matter what the program,
no matter what the language.
Fundamentally, computers just deal with numbers. They store letters and other characters by assigning a number for each one. Before Unicode was invented, there were hundreds of different encoding systems for assigning these numbers. No single encoding could contain enough characters: for example, the European Union alone requires several different encodings to cover all its languages. Even for a single language like English no single encoding was adequate for all the letters, punctuation, and technical symbols in common use.
These encoding systems also conflict with one another. That is, two encodings can use the same number for two different characters, or use different numbers for the same character. Any given computer (especially servers) needs to support many different encodings; yet whenever data is passed between different encodings or platforms, that data always runs the risk of corruption.
Unicode is changing all that!
Unicode provides a unique number for every character, no matter what the platform, no matter what the program, no matter what the language. The Unicode Standard has been adopted by such industry leaders as Apple, HP, IBM, JustSystems, Microsoft, Oracle, SAP, Sun, Sybase, Unisys and many others. Unicode is required by modern standards such as XML, Java, ECMAScript (JavaScript), LDAP, CORBA 3.0, WML, etc., and is the official way to implement ISO/IEC 10646. It is supported in many operating systems, all modern browsers, and many other products. The emergence of the Unicode Standard, and the availability of tools supporting it, are among the most significant recent global software technology trends.
Incorporating Unicode into client-server or multi-tiered applications and websites offers significant cost savings over the use of legacy character sets. Unicode enables a single software product or a single website to be targeted across multiple platforms, languages and countries without re-engineering. It allows data to be transported through many different systems without corruption.

Test Strategy 2
What is Test Strategy?
In simple words – Test strategy means “How you are going to test the application?” You need to mention the exact process/strategy that you are going to follow when you will get the application for testing.
I see many companies follow test strategy template very strictly. Even without any standard template you can keep this test strategy document simple but still effective.
Simple Tips to Write Test Strategy Document:
1) Include product background in test strategy document. In first paragraph of your test strategy document answer – Why stakeholders want to develop this project? This will help to understand and prioritize things quickly.
2) List all important features you are going to test. If you think some features are not part of this release then mention those features under “Features not to be tested” label.
3) Write down the test approach for your project. Clearly mention what types of testing you are going to conduct?
I.e. Functional testing, UI testing, Integration testing, Load/Stress testing, Security testing etc.
4) Answer questions like: How you are going to perform functional testing? Manual or automation testing? Are you going to execute all test cases from your test management tool?
5) Which bug tracking tool you are going to use? What will be the process when you will find a new bug?
6) What are your test entry and exit criteria?
7) How you will track your testing progress? What metrics are you going to use for tracking test completion?
8 ) Task distribution – Define roles and responsibilities of each team member.
9) What documents you will produce during and after testing phase?
10) What all risk you see in test completion?
Test Strategy 1
How do you create a test strategy?
The test strategy is a formal description of how a software product will be tested. A test strategy is developed for all levels of testing, as required. The test team analyzes the requirements, writes the test strategy and reviews the plan with the project team. The test plan may include test cases, conditions, the test environment, a list of related tasks, pass/fail criteria and risk assessment.
Inputs for this process:
- A description of the required hardware and software components, including test tools. This information comes from the test environment, including test tool data.
- A description of roles and responsibilities of the resources required for the test and schedule constraints. This information comes from man-hours and schedules.
- Testing methodology. This is based on known standards.
- Functional and technical requirements of the application. This information comes from requirements, change request, technical and functional design documents.
- Requirements that the system can not provide, e.g. system limitations.
Outputs for this process:
- An approved and signed off test strategy document, test plan, including test cases.
- Testing issues requiring resolution. Usually this requires additional negotiation at the project management level.
What Test plan and what it consists?
What Test plan and what it consists for Software Testing Projects ?
Test plan: It contains item to test & it is a statagic document. It consists of
objectives ,scope ,approach and focus in software testing effort
Test Consist :
1)Revision history
2)Introduction
3)Objective
4)Process
5)Test Strategy
6)Entry/Exit Criteria
7)Schedule
8)Milestone
9)Deliverable
10)Commands
Types of Software Testing 2
The development process involves various types of testing. Each test type addresses a specific testing requirement. The most common types of testing involved in the development process are:
• Unit Test.
• System Test
• Integration Test
• Functional Test
• Performance Test
• Beta Test
• Acceptance Test.
• Unit Test.
• System Test
• Integration Test
• Functional Test
• Performance Test
• Beta Test
• Acceptance Test.
Unit Test
The first test in the development process is the unit test. The source code is normally divided into modules, which in turn are divided into smaller units called units. These units have specific behavior. The test done on these units of code is called unit test. Unit test depends upon the language on which the project is developed. Unit tests ensure that each unique path of the project performs accurately to the documented specifications and contains clearly defined inputs and expected results.
System Test
Several modules constitute a project. If the project is long-term project, several developers write the modules. Once all the modules are integrated, several errors may arise. The testing done at this stage is called system test.
System testing ensures that the entire integrated software system meets requirements. It tests a configuration to ensure known and predictable results. System testing is based on process descriptions and flows, emphasizing pre-driven process links and integration points.
Testing a specific hardware/software installation. This is typically performed on a COTS (commercial off the shelf) system or any other system comprised of disparent parts where custom configurations and/or unique installations are the norm.
Functional Test
Functional test can be defined as testing two or more modules together with the intent of finding defects, demonstrating that defects are not present, verifying that the module performs its intended functions as stated in the specification and establishing confidence that a program does what it is supposed to do.
Acceptance Testing
Testing the system with the intent of confirming readiness of the product and customer acceptance.
Ad Hoc Testing
Testing without a formal test plan or outside of a test plan. With some projects this type of testing is carried out as an adjunct to formal testing. If carried out by a skilled tester, it can often find problems that are not caught in regular testing. Sometimes, if testing occurs very late in the development cycle, this will be the only kind of testing that can be performed. Sometimes ad hoc testing is referred to as exploratory testing.
Alpha Testing
Testing after code is mostly complete or contains most of the functionality and prior to users being involved. Sometimes a select group of users are involved. More often this testing will be performed in-house or by an outside testing firm in close cooperation with the software engineering department.
Automated Testing
Software testing that utilizes a variety of tools to automate the testing process and when the importance of having a person manually testing is diminished. Automated testing still requires a skilled quality assurance professional with knowledge of the automation tool and the software being tested to set up the tests.
Beta Testing
Testing after the product is code complete. Betas are often widely distributed or even distributed to the public at large in hopes that they will buy the final product when it is released.
Black Box Testing
Testing software without any knowledge of the inner workings, structure or language of the module being tested. Black box tests, as most other kinds of tests, must be written from a definitive source document, such as a specification or requirements document.
Compatibility Testing
Testing used to determine whether other system software components such as browsers, utilities, and competing software will conflict with the software being tested.
Configuration Testing
Testing to determine how well the product works with a broad range of hardware/peripheral equipment configurations as well as on different operating systems and software.
Independent Verification & Validation
The process of exercising software with the intent of ensuring that the software system meets its requirements and user expectations and doesn't fail in an unacceptable manner. The individual or group doing this work is not part of the group or organization that developed the software. A term often applied to government work or where the government regulates the products, as in medical devices.
Installation Testing
Testing with the intent of determining if the product will install on a variety of platforms and how easily it installs.
Integration Testing
Testing two or more modules or functions together with the intent of finding interface defects between the modules or functions. Testing completed at as a part of unit or functional testing, and sometimes, becomes its own standalone test phase. On a larger level, integration testing can involve a putting together of groups of modules and functions with the goal of completing and verifying that the system meets the system requirements. (see system testing)
Load Testing
Testing with the intent of determining how well the product handles competition for system resources. The competition may come in the form of network traffic, CPU utilization or memory allocation.
Performance Testing
Testing with the intent of determining how quickly a product handles a variety of events. Automated test tools geared specifically to test and fine-tune performance are used most often for this type of testing.
Pilot Testing
Testing that involves the users just before actual release to ensure that users become familiar with the release contents and ultimately accept it. Often is considered a Move-to-Production activity for ERP releases or a beta test for commercial products. Typically involves many users, is conducted over a short period of time and is tightly controlled. (see beta testing).
Regression Testing
Testing with the intent of determining if bug fixes have been successful and have not created any new problems. Also, this type of testing is done to ensure that no degradation of baseline functionality has occurred.
Security Testing
Testing of database and network software in order to keep company data and resources secure from mistaken/accidental users, hackers, and other malevolent attackers.
Software Testing
The process of exercising software with the intent of ensuring that the software system meets its requirements and user expectations and doesn't fail in an unacceptable manner. The organization and management of individuals or groups doing this work is not relevant. This term is often applied to commercial products such as internet applications. (contrast with independent verification and validation)
Stress Testing
Testing with the intent of determining how well a product performs when a load is placed on the system resources that nears and then exceeds capacity.
User Acceptance Testing
See Acceptance Testing.
White Box Testing
Testing in which the software tester has knowledge of the inner workings, structure and language of the software, or at least its purpose.
Types of software Testing 1
There are several Software Testing Types are describe below:
Black box testing – Internal system design is not considered in this type of testing. Tests are based on requirements and functionality.
White box testing – This testing is based on knowledge of the internal logic of an application’s code. Also known as Glass box Testing. Internal software and code working should be known for this type of testing. Tests are based on coverage of code statements, branches, paths, conditions.
Unit testing – Testing of individual software components or modules. Typically done by the programmer and not by testers, as it requires detailed knowledge of the internal program design and code. may require developing test driver modules or test harnesses.
Incremental integration testing – Bottom up approach for testing i.e continuous testing of an application as new functionality is added; Application functionality and modules should be independent enough to test separately. done by programmers or by testers.
Integration testing – Testing of integrated modules to verify combined functionality after integration. Modules are typically code modules, individual applications, client and server applications on a network, etc. This type of testing is especially relevant to client/server and distributed systems.
Functional testing – This type of testing ignores the internal parts and focus on the output is as per requirement or not. Black-box type testing geared to functional requirements of an application.
System testing – Entire system is tested as per the requirements. Black-box type testing that is based on overall requirements specifications, covers all combined parts of a system.
End-to-end testing – Similar to system testing, involves testing of a complete application environment in a situation that mimics real-world use, such as interacting with a database, using network communications, or interacting with other hardware, applications, or systems if appropriate.
Sanity testing - Testing to determine if a new software version is performing well enough to accept it for a major testing effort. If application is crashing for initial use then system is not stable enough for further testing and build or application is assigned to fix.
Regression testing – Testing the application as a whole for the modification in any module or functionality. Difficult to cover all the system in regression testing so typically automation tools are used for these testing types.
Acceptance testing -Normally this type of testing is done to verify if system meets the customer specified requirements. User or customer do this testing to determine whether to accept application.
Load testing – Its a performance testing to check system behavior under load. Testing an application under heavy loads, such as testing of a web site under a range of loads to determine at what point the system’s response time degrades or fails.
Stress testing – System is stressed beyond its specifications to check how and when it fails. Performed under heavy load like putting large number beyond storage capacity, complex database queries, continuous input to system or database load.
Performance testing – Term often used interchangeably with ’stress’ and ‘load’ testing. To check whether system meets performance requirements. Used different performance and load tools to do this.
Usability testing – User-friendliness check. Application flow is tested, Can new user understand the application easily, Proper help documented whenever user stuck at any point. Basically system navigation is checked in this testing.
Install/uninstall testing - Tested for full, partial, or upgrade install/uninstall processes on different operating systems under different hardware, software environment.
Recovery testing – Testing how well a system recovers from crashes, hardware failures, or other catastrophic problems.
Security testing – Can system be penetrated by any hacking way. Testing how well the system protects against unauthorized internal or external access. Checked if system, database is safe from external attacks.
Compatibility testing – Testing how well software performs in a particular hardware/software/operating system/network environment and different combination s of above.
Comparison testing – Comparison of product strengths and weaknesses with previous versions or other similar products.
Alpha testing – In house virtual user environment can be created for this type of testing. Testing is done at the end of development. Still minor design changes may be made as a result of such testing.
Beta testing – Testing typically done by end-users or others. Final testing before releasing application for commercial purpose.

SDLC and STLC
SDLC is software development life cycle which has the following stages.
2. Analysis
3. Design
4. Coding/implementation
5. Testing
6. Installation
7. Release and maintenance
Whereas STLC is software testing life cycle which is a part of SDLC and has the following stages:
1. Requirement
2. Prepare test plan
3. Review
4. Prepare test cases
5. Execute the test
6. report analysis
7. Bug analysis(log the bugs)
8. Bug report
9. Close testing
System testing and Functional testing
Functional testing -> is the technique utilized in the system tesing.Its a black box testing type... Functional testing is noting but testing or check whether a sytem functions properly as per the req..
System testing -> is the phase after integration testing phase.After all modules get integrated and tested for integration, the system is tested as a whole.

Why we are Useing Stored Procedures ?
There are several advantages of using stored procedures instead of standard SQL.
1. Stored procedures allow a lot more flexibility offering capabilities such as conditional logic.
2. Because stored procedures are stored within the DBMS, bandwidth and execution time are reduced. This is because a single stored procedure can execute a complex set of SQL statements.
3. SQL Server pre-compiles stored procedures such that they execute optimally.
4. Client developers are abstracted from complex designs. They would simply need to know the stored procedure's name and the type of data it returns.
