Process Modeling - Process based model (Entity based)


A process-based model is a model that takes an object-oriented perspective, identifying:

  • the relevant entities (included properties)
  • their state
  • and their behaviors.

A process-based model is focused on the actual state of an entity whereas a event-based model is focused on the state changes.

All activities owned by an entity are grouped into a process, which can then be viewed as that entity's lifecycle. Lifecyles are described from the entities perspectives. This includes all relevant activities, the sequence in which they occur, and their relationship to other entities in the model. (UML activity diagrams).

Same as Procedural_programming.


Identify entities

The first step in designing a process oriented model is to identify the relevant active entities. If the entities have the same “behaviour”, they can all be classed as one type of entity.

Describe the behavior / lifecycle

The second step in designing a model is to describe the behavior of every type of entity.

This phase aims to get a clear idea of:

  • what these entities do
  • and how they interact.

They describe the sequence of activities

You can describe the lifecycle of each entity with the help of:
