Development Highlights
PHP 5 and MySQL 5 was used for the development of this site to accommodate the social networking nature of the website. Advertisers, Publishers, Banner Management and Payment facilities modules were developed using PHP so that they can be directly executed using the UI. An interface translating the object logic to relational logic was used to communicate with the relational databases in an object oriented manner. This enabled effective access to the database. The intermediary abstraction layer ensured ease of access of data from database. Triggers, stored procedures and custom MySQL functions used for complex calculation of data from multiple tables. Conditional syntax was used to ensure smooth functioning of the website. The UI layer was isolated from business logic and images, apps and data was called from their respective servers. Web usability guidelines were strictly followed and AJAX, CSS3 and HTML5 controls were used to make the site’s navigation more intuitive and user friendly. The site was developed and fully functional within a span of 6 months.
