2SYSTEM DESIGN
Introduction:
The system design is done for visualizing the static and structural properties of the
system. The UML diagrams are the main tool for developing the dynamic and static patterns of
an object oriented system. The UML diagrams are often used in the design phase of other object
based systems.
The system has been developed based on the information of IT Solutions and their need
for new system. The organization requires a new system that can hold the information of the
service requests and progress status of the request.
