Analysis class diagram
Description
A class diagram is a diagram used in unified modelling language (UML) to show the static view of the
system being modelled (Felici, 2011). It provides a visual description of the operations and attributes of
the classes making up the system. It also shows the relationships existing between different classes.
A class diagram is used throughout the development life cycle of the system. In the early stages of the
development, the analysis class diagram is used to give a visual representation of the system and a
description necessary in understanding the implementation of the system. During the actual
implementation, the class diagram can be used to generate code by using CASE tools like enterprise
architect while also documenting the system.
