Arthur J.riel once said that you do not have to strictly abide by these principles and will not be sentenced to religious punishment for violating them. But you should think of these principles as alarms, and if you violate one of them, the alarm will ring. So, whatever we do, we have to have a principle. Programming is no exception, the following describes PHPThe principle of object-oriented
Design class---> Design class is the abstraction of one or more objects in a system implementation.---> Design classes have been mapped directly to the implementation code, so the design class relies on the implementation language. On the other hand, the design class origina
Good questions about object-oriented analysis and design. it may take some time for the younger brother to get in touch with object-oriented design. every time you

not change operations into classes. Question any class whose name is a verb or a derived Automatic Word, especially a class with only one meaningful action. Consider whether the meaningful behavior should be migrated to an existing or undiscovered class.(21) We often introduce a proxy class when creating an analysis model for an application. In the design phase, we often find that many agents are useless a

Consider whether the meaningful behavior should be migrated to a class that already exists or has not yet been discovered.(21) We often introduce proxy classes when creating an application's analysis model.

Reading directory: 1. Background 2. Ask yourself, does UML make sense to you? Does it help you analyze and model the system? 3. We have been separated by a gap for a long time, making OOAD inaccessible. 4. The four-color prototype fills this gap in history, so that we can see the hope of OOAD. 5. Use color Modeling on four-color prototype to enhance visual impact 6. Create a domain-independent model using four-color prototype 7. Conclusion: you can skip the specific implementation during

: Pinterest, silk Books, Thread, ebook, and so on, you will certainly classify these types as sub-types of books, which is refinement. You need to draw a shape that can be a rectangular, round, messy shape, so you just need to manipulate the shape type, such as adding a behavior to the shape type: painting. The type of refinement: rectangular round-shaped shapes each define their own picture behavior. You just need to get a shape-thinning
