I decided to study UML in March to prepare for the subsequent group training.

"To do well, you must first sharpen your tools "! UML is a "nuclear weapon" in the hands of analysis designers and must be well studied.

 

I bought a book, but it hasn't arrived yet. It should be this week.

Now I am reading the UML tutorial of <Shang xuexiang>, and I feel like I am doing well.

Key components:

1. Use Case, especially include, extends, and Generalization

2. Dependency and association in class digoal should be further understood.

3. Activity digoal, which seems to be a type of Flowchart

4. Sequence digoal, not very skilled.

5. Deployment digoal. I don't know what it is.
