Elements of the Analysis Model

Requirements Engineering - Elaboration

An analysis modeling task

* Use cases are developed 

* Domain classes are identified along with their attributes and relationships

* State machine diagrams are used to capture the life on an object

The end result is an analysis model that defines the functional, informational, and behavioral domains of the problem  

Elements of the Analysis Model

• Scenario-based Elements

• Class-based Elements

• Behavioural Elements

• Flow Elements

Scenario-based elements

Describe the system from the user's point of view using scenarios that are depicted in use cases and activity diagrams

Class-based Elements

Identify the domain classes for the objects manipulated by the actors, the attributes of these classes, and how they interact with one another; they utilize class diagrams to do this

Behavioural Elements

Use state diagrams to represent the state of the system, the events that cause the system to change state, and the actions that are taken as a result of a particular event; can also be applied to each class in the system

Flow Elements

Use data flow diagrams to show the input data that comes into a system, what functions are applied to that data to do transformations, and what resulting output data are produced
