Planning Keeping in mind the enormous structure of the website and the challenges involved a four-tier development approach was adopted consisting of: • The Database layer containing MSSQL Server Database, Tables, Stored Procedures and so on.

• The Data Access layer containing the libraries responsible for accessing data from the database.

• The Business Logic layer consisting of all the business logic procedures for modules like user profiles, groups, registration info etc.

• The User Interface layer which forms the Graphical User Interface of the website.

Architecture We used 4-tier architecture which consists of Presentation layer (PL), Business Access layer (BAL), Data Access layer (DAL), Database layer (DL).

DL: Database layer contains MSSQL Server Database, Tables, Stored Procedures and so on.

BAL: Business Access layer contains business logics and validations related to the data.

DAL: Data Access layer contains methods which help the Business layer to connect the data and perform the required action such as returning data or manipulating data (insert, delete, update).

PL: Presentation layer contains .asp or html where data is presented to the user as well as the inputs is taken from the user.

Deployment Architecture For deployment, we are using Windows Server 2008 with IIS7. Also, we are using MVC architecture. The benefits of MVC are: 1.
