What is the relationship between the use case model and static model (class diagram) for developing an object-oriented software system?
The class diagram actually shows the structure of the proposed system.It includes classes, attributes, operations and also the relationship between classes.
Use case diagram is actually the one designed from end user perspective.It consists of several usecases.Usecases specify the expected behaviour of the system.
Both of these models are coming under UML(Unified Modelling Language).Class diagram coming under structural diagram and usecases coming under behavioural diagram.
Both of these models are important in the development of object oriented software system.Class diagram helps the developers and team members to understand the static structure of the system.Use case digram helps to communicate the system requirements in terms of user perspective.
