The polymerization is included, but it doesn't matter, it doesn't matter. For example, there are students in the flight. It is also a polymerization of a student flight. It is a "HAS A" associated combination is an object being integrated by many things, missing However, such as the pencil is composed of a pen, it is not a combination of a large number of objects integrated with a lot of particles, many of which belong to high-polymer coupling, chain loose, becoming a loosely coupled, reverse, tight coupling abstract is for certain affairs Summary, find a regular package is to hide some attributes, there is a divided point of view, the largest shortcomings in the inner view waterfall is to change the user's demand, and the entire framework requires all USDP is a hierarchical application for Waterpool, each layer. Inside, a Waterpool prototype is to create a foreseeable solution. Use an example to use an ellipse, you need to use priority training. The generalization of each project is inheritance. The association corresponds to the C language is a call relationship. Relationships of associations, a class, a class that implements another class, method, etc., can use the Delegate aggregation and combination to illustrate diamond (filling / filler black), such as A, B, A, A-contained Class B, a method of calling A, actually executing a method of B is executed in the functional sequence diagram of A. It is the line sequence diagram when not executed, is the line sequence diagram, which is the order of execution of the function. , Call collaboration map between objects, the change in the state
