Technologies Used

Manpower

Planning

To equip the site with the numerous functionalities and features, a four tier development approach was adopted:

• Database Layer – Consists of MySQL database, tables and stored procedures
• Data Access Layer – consists of the Data Access DLL that accesses data from the database.
• Business Layer – contains the business logic procedures for the various modules like Offices,
  Properties, Maps etc.
• User Interface Layer – this forms the user facing Graphical User interface.

Architecture

The following layers of the n tier architecture were loosely coupled to efficiently meet the needs of this enormous site.

• User Interface Layer –This layer accesses the layers beneath it to present data. It is a
  page level layer.
• Business Specific Layer – acts as a bridge between UI layer and Database Layer.It contains the business logic for all the project components.
• Database Specific Layer – acts as a bridge between the physical database and the business logic.
• Physical Database Layer – This is the MySQL database with tables, views and stored procedures.

Development highlights

PHP 5 and MySQL 5 was used for the development of this site to accommodate the social networking nature of the website. User Profiles, Invitations, Forums and Blogs 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.
