The Framework

We can design a framework using Profile, Stage, Action and MessageContext.

1. A Profile executes a list of Stage in sequence
2. A Stage executes a list of Action in sequence
3. An Action executes the actual logic
4. A MessageContext is an object instance that is passed from action to action during runtime. It stores details and states of the profile flow.

Profile

Attributes:

1. Profile Id
2. Default Profile Id
3. Description

Consider Profile Id as a product name derived from unique combination of product attributes.

For example, a product can be uniquely identified using :

### Stage Attributes: 1. Stage Id 1. Stage Name 1. Stage Description 1. Stage Order 1. Flow Id I ### Action Attributes: 1. Task Id 1. Task Name 1. Task Description 1. Task Order 1. Stage Id
