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 MySQL Server Database, Tables, Stored Procedures and so on.
• 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.
• The User Interface layer which forms the Graphical User Interface of the website.

Architecture
The online networking characteristic of the website called for the design approach to be built around
PHP and MySQL Server. Modules like User Profiles, Invitations, Forums and Blogs were developed in
PHP such that they can be executed directly from the UI layer. These PHP files consisted of all the
business logics used for respective modules like Save (Add/Update), Delete, Get Single Object, Get
Multiple Objects for Listing and were designed to be capable of handling many more logics which
were not related to the database. 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 data from multiple tables and were entirely
avoided with conditional syntax to ensure 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. Sub-domains were used for the different areas of the website to guarantee scalability. Third
party package (iLance) was integrated to provide a crowd-sourcing platform.
Development Highlights
The site was equipped with robust architecture to offer centralized access handling two different
roles. Extensive pre-development research was carried out in order to integrate the third-party chat
tool and build a fully-functional system according to the latest standards. SEO activities performed
ensured high visibility for the site over the internet. Web usability guidelines were strictly followed
during development and the interface was made easily navigable through judicious use of AJAX, CSS
and HTML controls. The site was developed and fully functional within a span of 8 months.
