Project Challenges
Team faced the following challenges:
• Developing an online & Desktop Dealer Management POS System that has the routing
mechanism so that dealers can fill it and route it to Bridge Stone. Generating complex
reports which involved extensive querying of database without slowing down the site.
• Implementing POS Screen that pull information from CRM backend and manage data
online and offline both.
• Providing and maintaining the database of a range of interactive features like mail
service, sales & expenses, events announcement and reminders.
• Incorporating web usability principles in the website design so as to ensure easy
navigation for all types of users.
• The most important of all was to ensure data security.

Technologies Used
Manpower
Planning
• The design approach was built around JSP using JSTL, Servlets and MYSQL Server due to the
performance, security, scalability and the nature of the website. In addition to this, the
development structure was specifically implemented to facilitate the 'Faster to Market'
transition of such concepts.
• 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
the data from multiple tables and were entirely avoided with conditional syntax to ensure the
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.
Operating System Linux Cent OS, POS Desktop for Windows, Multi-Server Architecture with
Staging & Production environment through Version controlling releases

performance tuning at regular intervals, software firewall configuration
and maintenance, email server configuration etc.
Development Environment Java, Swing, J2EE, JSTL & Servlets, Spring XML Web Services, Java
Script, AJAX, Tomcat Apache 6.0.28

Architecture
Keeping in mind the enormous structure of the website and the challenges involved n-tier
architecture was adopted with all the layers loosely coupled with each other as follows:
• Presentation Specific Layer: This will include the page level layer which will be accessing
the other layers beneath to present the data.
• Business Specific Layer: This will be the bridge between the presentation layer and the data
base layer. This will contain all the business logic for the different components involved in the
project.
• Database Specific Layer: This will be a bridge between the physical database and the
business logic accessing the data.
• Physical Database Layer: MYSQL5 with the tables, views, stored procedures etc.
