  • A three tier development approach was used for this project taking into account the enoromous nature of the project.
  • Proper planning was required to enable synchronization and connectivity of the web server and database server where images were stored.
  • To be able to get actual level of output from different verticles and business logic, research and analysis had to be scheduled.
  • Data access layer: contained the libraries that are used to access the data from the database.
  • Business logic layer: contained all the business logic procedures for modules used for profiles, registrations, groups info etc.
  • User Interface Layer: this is the Graphical User Interface that forms the front end for users.

The project was carried out successfully with the use of technologies like PHP and MySQL. Access to the database was effectively implemented with the help of an interface translating the object logic to relational logic so that relational databases could communicate in an object-oriented manner. An intemediary abstraction layer was created to enable smooth database access. Stored procedures were used to retrieve complex data from multiple tables and conditional syntax was implemented to ensure the seamless performance of the website. The UI layer was isolated from the business logic by placing images and applications that could be called from their respective servers. Sub-domains were implemented for various areas of the site. This ensured scalability. Customizing the ecommerce integration with 3rd party was effectively implemented using CodeIgniter.

Development Highlights
Coupons and offers kind of websites require an achitecture that ensures quick marketing capabilities. Hence this project used all major complex queries and yet maintained an easy to use interface for the user. Search and browse options were optimized using complex query features. Strict adherence to the usability guidelines were followed and the interface was easily navigable through the judicious use of AJAX, CSS and HTML controls. SEO (Search Engine Optimization) activities on a regular basis ensured that the site gets visibility and traffic quickly. The application was complete and fully functional within a span of 3 months.
