First install StarUML (baidu can find many)

Just open the software and select the Default Approach

1. Draw domain model (static structure of business domain/business body)

Major relationships

The main process

  • Add the class
  • Add attributes to a class (right-click class -> Add ->Attribute)
  • Mark the relationships between the questions

  • Point relationship line
  • Click on two solid blocks to select multiplicity (some relationships do not have this option)

Multiple use of “..” To express, 0.. N means zero to infinitely many, 0.. 1 means zero or one, 3 means three, 0.. 5 indicates 0 to 5

Note: All yellow backgrounds can be changed directly to white (for clarity when printing documents).

Select all (Ctrl+A), copy (Ctrl+C), and paste (Ctrl+ V) into Word as an image

2. Business flow chart

  • Right-click Untitled to add Package

  • Right-click Package1->Add Diagram ->Add Activity Diagram

The interface is not too difficult, so I won’t introduce it

Note: The activity diagram must contain the starting point (InintalState) and the ending state (FinalState).

3. Activity diagrams

A project can hold multiple images, and the key content of the toolbar is similar to that of the domain model

Simple example:
