Sixth package DiagramKey concepts:1. package Diagram (Diagram)Consists of a number of packages and the relationships between the packages. A packet is a grouping mechanism that sets up some related classes as a package, forming a high cohesion , low-coupling class collection, which can be said to be a package equivalent to a subsystem.2. Brief introduction:Package diagrams is an important modeling

Introduction to the basic concepts of UML:
UML:UML (Unified Modeling Language) provides a unified, standard, and visual modeling language for object-oriented software design. It is suitable for describing the whole process of software design which is driven by use case and is architecture-centric.

A use case diagram must include a description of the function, a role, and a role and function correspondence.Role (actor):A role in a software system is the idealization of an external person, process, or thing that interacts with a system, subsystem, or class.

that the sender passes a message to the recipient of the message, and then resumes its activity without waiting for the recipient to return the message or control. The recipient and sender of an asynchronous message are working concurrently. The return message means that the message is returned from the procedure call.Self-correlating messagesRepresents the method's own invocation and one method within an object that invokes another method, such as:C
page-oriented server-side call, usually a form is submitted, and these event parameters represent fields in the form.
Page Variables)The page variable definition method is similar to the event parameter. The difference is that the page variable is defined in the input stream of the client action status. These page variables can be used on the generated JSP page ..
Decision Point (demo-points)In some cases, it is not enough to have an action or a stream. For example, if the user logs on successf
Most of the models in UML describe the logic and design information:

UML Modeling Detailed: Basic Concepts use case diagram Class
UML defines the following 5 categories, 10 model diagrams.
The first class is the use case diagram, the use case diagram describes the function of the system from the user's point of view, and points out the operator of each function.
The second category is static diagrams, including class diagrams, Object diagrams, and package diagrams. The class
A class Diagram shows a set of classes, interfaces, and collaborations and their relationships. These diagrams is the most common diagram found in modeling object-oriented systems. Class diagrams address the static Design view of a system. Class diagrams that include active classes address the static process view of a system. Component diagrams is variants of class diagrams.The class
First, the concept of a state diagramA state diagram, also called a state machine diagram, represents the state of a model element during its life. From the start state of the model element, respond to events, perform certain actions, cause the state to move to a new state, respond to an event in a new state, execute an action, cause to move to another state, so continuous, until the state is finalized.In a

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 class diagram as an efficient communication tool, the de
