  • In order to most effectively access the database in an object-oriented context an interface translating the object logic to the relational logic was used to communicate with the relational databases in an object-oriented manner. An intermediary abstraction layer was created for accessing data from the database. Stored procedures were used only for complex retrieval of the data from multiple tables and were entirely avoided with conditional syntax to ensure the smooth performance of the website. The UI layer was kept free of any business logic with images, applications and data being called from their respective servers.
  • The design approach was built around JSP using JSTL , Servlets and MYSQL Server due to the performance, security, scalability and the nature of the website. In addition to this, the development structure was specifically implemented to facilitate the ‘Faster to Market’transition of such concepts.


Keeping in mind the enormous structure of the website and the challenges involved n-tier architecture was adopted with all the layers loosely coupled with each other as follows:
  • Presentation Specific Layer: This will include the page level layer which will be accessing the other layers beneath to present the data.
  • Database Specific Layer: This will be a bridge between the physical database and the business logic accessing the data.
  • Business Specific Layer: This will be the bridge between the presentation layer and the database layer. This will contain all the business logic for the different components involved in the project.
  • Physical Database Layer: MYSQL5 with the tables, views, stored procedures etc.
