List some of the similarities/ differences between a use case diagram and a context diagram?(basics)

Solution

The similarities between the two are as follows:

1) Both the models are responsible for designing what is inside gthe system and what is outside the system.

2)Both the models afre responsible for defining the system boundaries for the outside entities and and components of the system linked for the inside objects.

3)The feature of generalisation can be applied to the both diagrams for the outside entities.

4)Generalization cannot be applied on the inner components in both the diagram.

Differences:

1) Context diagram is something that transforms the data whereas Use case diagram defines the services and functions.

2)When we expand a context diagram it is expanded into a more detailed data-flow diagram asthey form same hierarchy of models . use-case model is expanded into a class model .
