uml课后习题（UML after-school exercises） Modeling and analysis design of UML system Chapter 1 is the evolution of system modeling and analysis design 1, the three elements of system modeling: methods, tools, and processes 2. Classification of software: According to the functional division of software: system software, support software and application software According to the size of the software division: small software, medium-sized software, large and even super large software According to the way the software is divided into: real-time processing software, time-sharing processing software, interactive software and batch processing software According to the scope of the software service object division: one-time use of software and the use of higher frequency software According to the extent of the impact of software failure Division: general software and critical software 3, there are two reasons for the software crisis: one is related to the characteristics of the software itself; two, the method of software development and maintenance is not correct. 4, software development process model: waterfall model, incremental model, evolution model, spiral model, intelligent model 5, UML features: uniqueness, continuity, maintainability, reuse and gradual improvement 6, object oriented three important features: encapsulation, inheritance and polymorphism 7, the software development method is a gradual evolution process from the structured development method, the modular development method to the object-oriented development method 8, the software life cycle describes the whole process of defining, developing, using, maintaining, and taking a software 9. The basic concepts of object oriented are object, class, emergency, encapsulation, polymorphism, inheritance and message passing 10, the software development process consists of four four phases: client requirements analysis, system analysis, system design and system implementation, testing and maintenance 11, the object-orie
