Feasibility Analysis:
Technical: NodeJS and MongoDB will be used to develop the system of Sunshine Motor
Vehicle Service and for the front end system angular, html and CSS will be used. The used
technologies are very strong and free to use. Real time data flow integration will be done by
socket IOs.
Financial: The use of NodeJS and MongoDB will help to make the system more robust
and the system will be developed in a cloud environment and these technologies are open source.
Although the overall cost for this system will be higher than traditional ASP and PHP
applications.
Organizational Feasibility: For the system to handle the entire business processes
efficiently the system needs to be sturdy, reliable and should be able to process queries and
handle the huge load of data flow. Manual system of the Sunshine Motors will be converted to
automatic with the help of this proposed system.
Requirement Specifications:
Functional Requirements:
Authentication: Authentication is the process of checking is a customer is valid or not to
access the system with the help of the customer Id and password. There are other methods for
authentication process also but, as per the scenario, using an id and password is the best way to
implement this in the organizational system.
Authorization: Authorization is the process of granting a user to access the requested
data. There are different levels of authorization for different users and this will be done using the
customer id and password.
