Read the Asg_RH documentation to build a domain model by use case
- According to the requirements of Task2, please use the tool UMLet, the screenshot format must be png and control the size.
- Note: Please do not be affected by the PCMEF hierarchy. You need to identify the entity (E) and the intermediary entity (M, also known as the state entity)
- In single-page applications (such as vue), E is generally related to database construction, and M is generally related to store mode
- In java web applications, E is generally related to database construction, and M is generally related to session

Similarities and Differences Between Database Logical Model and Domain Model
- different
- The domain model is mainly the product produced in the requirement phase, and is a conceptual product that is extracted from the analysis and summary of the requirement to describe the business requirement.
- The database logic model is more inclined to the development process, taking into account the tables that are really to be stored at the database level, etc., which is convenient for subsequent program design.
- same
- All conceptual classes of the software are represented graphically, and they all show the names, attributes and relationships of each conceptual class.
