Part 1: Introduction to OOAD 2 Objectives What we will learn: Introduce oo concepts. Compare and contrast analysis and design. Define object-oriented analysis and design (OOA/d ). Revoke strate a brief example. 3 What is object technology? A set of principles (Billing action, Encapsulation, Polymorphism) Guiding Software Construction, Together Ages, databases, And other tools that Support those Principles.

Pattern (analysis pattern, Architecture Pattern and design pattern) is a topic that we discuss extensively. It is researched to improve software reuse (CodeReuse and design reuse. Model development andOoLanguage development,OOADDevelopment of methodology andUMLDevelopment is closely related.

I am in charge of OOAD courses during blog training. As there are many content involved, I have compiled a Summary of the course summary, and hope you can give us valuable comments and guidance.

Following this principle leads to flexibility, reusability, and maintainability. Other design principles (the Richter replacement principle, the dependency reversal principle, the combination/aggregation multiplexing principle, the Dimitri rule, the Interface isolation principle) are the means and tools to realize the open and closed principle.The knowledge of

each module can be used independently of other places. The larger the size of a system, the more important it is to conceal information, and the greater the importance of information hiding.The main purpose of the Dimitri Law is to control the overload of information :In the division of classes, we should try to create loosely-coupled classes, the lower the coupling between classes, the more conducive to reuse, a loosely coupled class once modified, will not cause too much impact on the associa

ways:The class behavior pattern: The behavior pattern of a class uses an inheritance relationship to distribute behavior among several classes, and the class behavior pattern allocates the responsibilities of the parent class and the subclass primarily through polymorphism.The object behavior pattern: The object's behavioral pattern uses the object's aggregate affinity to assign the behavior, and the object's behavioral pattern is to assign the responsibilities of two or more classes by means o

OMT Method The OMT method was proposed by James Rumbaugh and other five people in 1991. Its classic book is "Object-Oriented Modeling and design ". This method is a new object-oriented development method. The basis of the development work is to model objects in the real world, and then use a

If you want to write only a few hundred linesCodeOfProgramYou can write it out quickly without designing it. But what do you do if you want to write a code program with several million lines and tens of thousands of lines? The level of programmers may only pass the big problem and the test of big projects can be seen. The following is an analysis of how to solve big problems (large projects) from an object-oriented perspective) 1. fully communicate with customers and analyze what systems t

Users' Requirements are usually incomplete and inaccurate. Sometimes, some important details have not been written into the requirements. Maybe users have forgotten them, but more often they think that those things are natural and take for granted. however, developers are not clear about these "natural events. No matter how many requirements documents are written, it is necessary for us to repeatedly communicate with users to refine the requirements and clarify the details. Often, "Details det
