•

The Interface layer and Database Abstraction layer for converting data between incompatible type systems in databases and accessing data from the database respectively.

•

The Business Logic layer consisting of all the business logic procedures for modules like User Profiles, Invitations, Forums, Blogs etc.

Customizable viewing options were designed to enhance user experience and allow personalization. Considering the enormous structure of application the development and deployment part was divided into four phases. Best techniques and hierarchical development approach was adopted to build a fully-functional system according to the latest standards.

For effective performance WCF web services were used. SAP integration was performed to connect with the existing data source and fetch the data and make it compatible with the developed web application. Web usability guidelines were strictly followed during development and the interface was made easily navigable through judicious use of AJAX, CSS3 and HTML5 controls. The site was developed and fully functional within a span of 6 months.
