What units of the software does the various diagrams of UML correspond to?

xiaoyu2032

The question that has been confused: What kind of software corresponds to the various UML diagrams, such as what diagrams correspond to the results after the outline design, what diagrams correspond to the detailed design structure of a module, and what diagrams can correspond to a certain module Design results for each unit. Let's also suppose that I now want to be able to write unit test cases for the units described by the UML diagram by seeing a UML diagram. What kind of diagram should this UML diagram be?

UML uses 4+1 views, the so-called 4 refers to (1) logical view, (2) process view, (3) implementation view, (4) deployment view
, 1 refers to the use case view. In the specific tools, Rose uses View (view) and PowerDesigner uses Model (model). Corresponding to the software development process, in the requirements acquisition phase, the general use case diagram captures user requirements. At this stage, the use case process must be refined and drawn Sequence diagram, so use case diagram is the basis for subsequent stages. In the analysis phase, class diagrams are drawn based on the discovered classes such as use case diagrams and sequence diagrams. Therefore, to write unit test cases, you must refer to the use case diagram, use case specification document, and sequence diagram.

你就从了吧

The class diagram corresponds to the class in the program,
The sequence diagram corresponds to the main code of each method of the program

I generally use 5 pictures
1. Use case diagram: describe the needs of the customer. But the focus of use cases is not the diagram, but the use case description
2. Activity diagram: used to describe the system processing method for the current use case. That is, the use case will be described from the back
3. Timing diagram: used to analyze the execution steps of the use case
4. Class diagram: obtained from the sequence diagram
5. Component diagram: This is less used, but it will be used when doing system analysis. I am not sure about the details, this is done by a system analyst

There is an uml model of the library management system, you can download it for reference, from requirements, analysis and design to final deployment, all kinds of uml diagrams are available, download address: http://www.5iuml.com/read.php?tid =252
