Software Engineering Process and object-oriented design summary

I always wanted to sum up the software engineering process and object-oriented design. If I had learned so much, I would not have learned it.

For software engineering, there are five major processes:

I. project conception. Generally, a system vision will be formed, including the overall goal and System feature documentation.

2. You need to obtain it. Obtain the functional and non-functional requirements of the system through various methods.

Iii. Architecture Decision-Making. The system features and non-functional requirements specification in the vision document generated in the previous two steps form an architecture decision document by extracting system quality attributes.

4. domain analysis. In this step, the concept layer class chart is formed by looking for important nouns and dynamic nouns in the requirement.

V. system design. This step is mainly based on the Concept layer class diagram and architecture decision document, design layer class diagram design.

The following describes the basic steps of object-oriented design:

1. design the Object Class Based on the Concept layer class diagram.

2. design the operation portal of the object class, such as the manager class and the container class.

3. Design the business logic class according to the nine principles of grasp. The activity diagram is involved.

4. Use Cases. It generally involves class diagrams and Collaborative Plotting.
