Recently, the book "Elephant" has been read, from last November to the present, for a full five months. On the one hand, because of the work of this period of time, life things are more, very little time to read the whole block; On the other hand is also reading this book, while reading the side of the expansion, the last recorded 13 notes. Elephant Thinking in UML learning Note (a)-why UML is required. "

This articleArticleNice http://technoboy.iteye.com/blog/998458 too ======================================================= In fact, I have always thought that UML is a very useless thing and never learned much. It is enough to look at the UML diagram drawn by others occasionally. Dramatically, I have seen the most UML companies (actually the only one) and the

First, as a modeling language, the definition of UML includes two parts of UML semantics and UML notation. UML semantics: Describes the definition of exact meta-model based on UML. UML notation: Defines the representation of

there is no loop in the instance diagram. In other words, it can only be a one-way relationship. Figure F Synthesis (composition) Synthesis ( fig. G) is a special form of aggregation, implying "local" within the "whole" life-cycle responsibility. Synthesis is also not shared. Therefore, while the part does not necessarily have to be destroyed with the destruction of the whole, the whole is either responsible for maintaining a partial survival state or for destroying it. Local cannot be shared w

is, object a relies on object B to complete an operation, so is this relationship also an "association"? Personally, this does not belong to an "association relationship". Because of the three relationships we mentioned above, each of these relationships, in addition to being a fixed relationship, has an important characteristic that these relationships need to be "persisted, preserved". A dependency is just a reference (or invocation) relationship between an object and an object, which occur

Component diagram, English name Yue: Component diagrams is used to describe the organization and dependencies between a set of artifacts, for the static implementation view of a modeling system, which can be executable programs, libraries, tables, files, and documents, and includes implementation information for logical classes or logical classes. Therefore, there is a mapping relationship between the structure model view and the implementation. Component diagrams can also include or subsystem,

Package diagrams is a combination of model elements that are represented in UML in a notation similar to a folder, each element in the system can be owned by only one package, one package can be nested in another, and a package diagram can be used to classify the related elements into a system that contains a package, chart, or individual element. In simple terms, we can directly understand the package as a namespace, a folder, is used to organize the

the relationships between classes Inheritance Relationship An inheritance relationship is the most understandable relationship. The picture is like this. The object-oriented argument is the is-a relationship. That is to say Class2 is a Class1. In C + + we say that Class2 is a derived class of Class1, or that Class1 is the base class for Class2. Aggregation and Composition Start with a relationship that is easy to understand. There is often a case where a class is a data member of another class.

In the nine diagrams of UML, the class and object graph are static graphs, and the reaction is the static process of the system. The class diagram is described earlier, and the following is the object graph. One, the object graph summary Two: Object Graph example The object graph is concrete, and the class diagram is abstract. such as the admin class in the class diagram. The straight line object belongs to the shape class and consi

The drink remodeling series has been completed by about 1/3, and in these articles I used a few simple class diagrams to describe refactoring strategies. In a later article, I might use a slightly more complex UML class diagram to introduce. But before I do, I think it's necessary to introduce the 6 major relationships in UML class diagrams first. The 6 major relationships are inheritance (inheritance), imp
