One, the distinction of the concept Some people confuse object-oriented database design (i.e. database schema) with object-oriented database management system (OODBMS) theory. In fact,

involves the overall organization of software systems, global control, data access, and communication protocols between subsystems. In the MVC structure, the subsystems are divided into three types: model, view and controller.System design mainly describes the identification of design elements, data storage strategy, deployment subsystem and system design review. 1. Identifying design elements corresponds to the design elements of the analysis class

1, the Essence of software: Program + data + documentation. 2. Three-dimensional view of software engineering: Process + method + tool.3, object-oriented approach to the meaning of software engineering: From software engineering t

Object What is the software? This is a difficult question to explain. Simply put, it's some logical computer code. But from another point of view, it also has many kinds of meanings and many kinds of puzzles. For example, is software a tool? What is the relationship between it and the human mind? Should he have a personality or even a life? What is the future of

The term "Object-Oriented Software Design" and its related topics have become familiar to many developers and even get tired of hearing it. However, to attract attention and attract the attention of the "opposite sex", this topic is still a topic to choose this hot topic as the topic of this blog. Please forgive me. I also hope you can put down the shelf and skip

Ten principles of Object Oriented Software development (turn one) It is useful for developers to look back at the application. Consider whether the application has achieved the intended purpose? Did you follow the best scenario? Is there a better way to achieve the goal? Knowing new, you may find new ideas in retrospect. This paper presents 10 state-of-the-art

Object-oriented design is mainly about the concept of design, software architecture, system design, detailed design, application design mode, user interface design and design documents, object-oriented design is a more important stage in
