System Analysis & Design
Analysis Class Diagram
Analysis class diagram is a static structure diagram that graphically represents the system
structure and interaction by showcasing the system classes and associated attributes,
relationships, and dependencies. These diagrams are significant in system analysis and design
process as they provide a sense of orientation. The details of the system and the components
are provided through these diagrams. Also, a quick overview of the dependencies and
interaction between the different components in the system is provided by these diagrams.
The diagram assists the system design and development teams to execute the system
accordingly to incorporate the functional aspects and system qualities.
Decisions made during analysis class diagram
There are two types of staff which are involved in the “Record New Tour” use case but have
