The function of a C/S-based Real-time chat system logon module is described as follows:
The user enters the account and password through the loginform interface.

Abstract: this is an article about the unified modeling language, that is, the basic diagram used in UML. In this article, I will discuss the structure diagram, which is a new graph type that has been proposed in UML 2. Since the purpose of this series of articles is to help people understand the mark elements and their meanings, this article mainly involves
The approximate steps to get the requirements using class diagrams are as follows:1. Identify the class2. Identify the main properties of a class3. Describe the relationship between classes and classes4. Analysis, abstraction and collation of all types

In object-oriented processing. The core of the class diagram, which provides the primary rules for defining and using objects.It is the descriptive description of the class, the interface and the relationship between them, which shows each class in the static structure of the system, the model. First,
Drawing a picture for a while, it becomes increasingly felt that the EA is a powerful software, not just a drawing tool so simple. With the extension of learning time, now the code is not as arbitrary as before, think of what to knock on what, but to first draw (that is, the process of demand and thinking), but for now we, there will always be considered not comprehensive place, then hit the code when there are a lot of changes, and will be more and more, And the project acceptance of the code a

For Java virtual machine implementations that support the class file format version number 51.0 or higher, the Bootstrapmethods attribute in the attributes table must be correctly recognized and read. The Java 7 specification requires that any Java Virtual machine implementation can automatically omit several (or even all) of its unrecognized property entries in the Attributes tab
1. PrefaceA lot of knowledge about UML, the deep grasp of some software modeling ideas, need a certain accumulation of practice.before summing up the study of the design pattern , it is necessary to understand the design of the class diagram so that it is easy to understand the static structure diagram of the design pattern. 2.
A class chart is a type of static view. A class chart describes a static relationship. In my opinion, a class chart is a process of finding and drawing relationships. It is so difficult to find a class in this process.
The following figure shows the elements in the class
Class diagramThe class diagram shows the construction module of the object-oriented system. Depicts a static view of a model or part of a model, showing the properties and behaviors it contains, rather than describing the function or refinement of the operation in detail. Class diagrams are most commonly used to expres
Class diagrams are the most common UML diagrams used to describe the structural design of a system. These include class relationships and the properties and behaviors associated with each class. Class diagrams can represent an excellent representation of inheritance and composition relationships. To use the
