PrefaceUML Modeling, its importance is self-evident, although I have known its name during the university, but because of various factors are always picked up and put down, failed to continue to study, after several intermittent, has not continued to read a book in depth. Recently more and more feel that the reverse engineering (generated by the code UML) in the daily finishing of the importance and convenience, then picked up books, think should take
UML-united modeling language, unified modeling language-is an object-oriented visual modeling language. UML uses a set of visualized graphical symbols (such as class diagrams) as the modeling language. These symbols can be used to visually describe all aspects of the system. UML describes a model by establishing various relationships between graphs (such as the r

The UML class drawing method is the basis for learning design patterns. Through UML class diagrams, you can better communicate with everyone and easily express your own design ideas. It is like Mandarin, is a standard language.
This section introduces the UML class drawing method, which mainly includes

The three "allies" James Rumbaugh, Grady booch, and Ivar Jacobson created UML in 1995 and integrated their respective methods (OMT, booch development method, and OOSE) into a whole. In 1997, OMG used UML as an actual public standard.
To a large extent, UML is a graphical language used to describe, record, design, and construct a solution. The powerful role of
In the process of learning UML class diagram, UML class diagram relation is a problem that must be mastered, and there are six kinds of relationships in UML definition: dependency, genus, association, implementation, aggregation and combination. The definitions and representations of the methods are described below.Introduction to
The 14th chapter uses UMLBefore exploring the details of UML, we should first talk about when and why to use it. The misuse and misuse of UML has caused too much harm to the software project.14.1 Why ModelingModeling is to figure out whether something is feasible. When models are much cheaper than real entities to build, we use models to study designs.14.1.1 Why build a software modelUML is used when we hav

Unified Modeling Language (UML), also known as the Unified Modeling language or standard modeling language, was an OMG standard that began in 1997 as a graphical language that supports modeling and software development, providing modeling and visualization support for all phases of software development, Includes requirements analysis to specifications, to construction and configuration. The development of object-oriented analysis and Design (ooad,ooad
In UML, nine kinds of graphs are especially important. After understanding nine kinds of graphs, what is the relationship between the nine diagrams, who first who, who leads who will become the next big problem to consider.
