Brief Information about Software Developement Lifecycle(SDLC) Models?

- There are various software development approaches define and design which are used during development process of software.

- Those approaches are also referred as software development process models.

- SDLC models are 2 types.They are:

           1.Sequential Model

           2.Incremental Model

1.Sequential model:

           - Those models are best suitable for small size projects,where all SDLC activities will be carried out one after another for the entire project.

           - These model consists of two models.They are

                                     1.Waterfall model

                                     2.V model

2.Incremental Model:

           - Those models are besst suitable for big-size projects.

           - This model consists of 5 models.They are

                                     1.RAD Model

                                     2.Fish Model

                                     3.Prototype Model

                                     4.Spiral Model

                                     5.Agile Model

Exaplining about Testing Levels and Methods?

• Testing is the processing to test an application with an intention of finding defects or errors.
• In Testing,Four levels are available.

         They are :     1.Unit Testing

                          2.Integration Testing

                          3.System Testing

                          4.User Acceptance Testing

Note: 

  A. Unit Testing and Integration Testing combination is called "White-box Testing" & White-box testing means test the program by programmer,not the application.

  B. Collection of System Testing and User Acceptance Testing is called " Block-box Testing" & Block-box Testing means test an application by Quality Analyst/Client,not the program.

• In Testing, 2 methods are available.They are

                  1.White-Box Testing

                  2.Block-Box Testing

Explaining about Software Development Life cycle(SDLC)?

Today Iam discuss about SDLC.

- SDLC stands for Software Development Life Cycle.

- Without SDLC,there is no Software Project.

- Project means which is developed for specific client requirement.

- In real-time process,

      - In the IT company,projects comes to the company by CEO from clients.CEO(Chief Executive Officer) communicate with the clients to get a projects.

      - Once Project is assigned/conformed to specific company ,CEO arrange the meeting with Project managers and discussing about the project and assign that project to one specific Project manager.

                                           Before starts SDLC process,above 2 steps are done to the every project.

                         

  1st Step:

        Initialize the project and prepare a project initial note by Project manager.

 2nd Step:

        Specific requirements gathering from Clients by Business Analyst(B.A) and B.A prepares 2 documents like Business Requirement Specification(BRS) and System Requirement Specification(SRS) for understanding the project easily.

Definition of Testing and Different Types of Testing?

Hai friends...Today I share the information about "Testing tools".

Now a days Everyone calls Name as "Testing Tools".but In IT sector,we should call "Software Testing" is the actual name of  Testing Tools.

Definition of Testing:

           It's a process of to test an application with an intention of finding defects.

-->Testing is dividing into 2 types.They are:

1.Manual Testing

2.Automation Testing

1.Manual Testing:

    It's a process to test an application by giving input's and by observing output's manually is called Manual Testing.

2.Automation Testing:

     - It's a process to test an application with the help of tolls and software's i.e called Automation testing.

     - In Automation testing,Different types of tools are available.

         They are :  A) Quick Test Professional(QTP)[ HP company licensed tool]

                        B) Selenium(Open Source)

                        C) Load Runner

                             

Real-Time 3-Tier architecture Application Example using ASP.NET

In 3-Tier programming architecture, the application development is broken into three main parts.
These are:
1.Application/Presentation layer
2.Business Acess Layer(BAL) and
3.Data Access Layer(DAL).
These separations ensure independent development of those layers such that a change in one does not affect the other layers. For instance a change in the logic of the DAL layer does not affect the the BAL nor the presentation layer. It also makes testing easier in that a whole layer can be replaced with a stub object.

For example instead of testing the whole application with an actual connection to database, the DAL can be replaced with a stub DAL for testing purposes. The DAL deals with actual database operations. These operations are inserting, updating, deleting and viewing. The BAL deals with the business logic for a particular operation. The PL has the user controls for interacting with the application.

3-Tier programming architecture also enables re-use of code and provides a better way for multiple developers to work on the same project simultaneously.

2.Design you page as shown below,
                           

3.Add sub-folders and class objects within the App_code folder as shown below,
