Domain model design

 The main objective of domain design is to understand the exact domain problems and then draft a model that can be written in any set of language/technologies. For example, in our Flix One bookstore application, we need to understand Order Management and Stock Management.

Here are a few characteristics of the domain-driven model:

• A domain model should focus on a specific business model and not across multiple business models
• It should be reusable
• It should be designed in a way that it should be called in the loosely coupled way, unlike the rest of the system
• It should be designed independently of persistence implementations.
• It should be pulled out from a project to another location, so it should not be based on any infrastructure framework.
