complete. Significant progress has been made in serialization logic modeling due to changes in the symbol set of the sequence diagram in UML 2 ). Note the text I mentioned above: "The uml2.0 draft Specification has been adopted ." Indeed, the specifications are still in the draft State, but the key is that the draft specifications have been adopted by OMG, which is an organization that uses them until the

. Unified Modeling Language (UML) Just like building a tall building, we need to draw a building diagram to build a model. During the system analysis and design phase of software system development, we usually use modeling technology to build a model for the system. Many modeling technologies have emerged during the development of

ObjectiveMost of the UML describes the logic and design of the information. The implementation diagram is used to describe the realization of the narrative information. The implementation diagram contains a deployment diagram and a component diagram.Component diagram1. ConceptComponent

discussed below. Internal Structure One of the more useful functions of the UML 2 structure diagram is the new internal structure mark. It allows you to show how a class or another classifier is made up internally. This is not possible in UML 1.x, because the mark limits you to display only the aggregation relationships of a class. Now, in

. Constraints Specifies one or more rules to satisfy for some classes and interfaces, using free-text identifiers enclosed in curly braces in UML. Package Packages in UML correspond directly to packages in Java to represent hierarchies and organizational content. Relationship of Class

connection. The constraint is represented as {}.4. Typically in UML, the name of the specific instance is underlined, and the class, not the instance, is represented if there is no underscore. Note that the rule has an exception for instances in the interaction diagram, and the instance is represented by a lifeline diagram, with no underscore in its name.Typical

device or a software system running on a hardware device. -UML Representation　　　　　　　　　-node instance: the instance form of the node. The format is instance Name:node, similar to the class instance format, preceded by a colon with an instance name or without an instance name　　　　　　　　　　　　　　-node type : Depending on whether the node is capable of-Processor: A node with the ability to perform

In the previous article "UML System Analysis and Design 02-use case diagram and activity diagram (I)", we mainly explained the use case analysis and drawing methods and techniques in requirement analysis, however, the use case diagram only tells us what the system wants to do. As for how to do it, there is no intuitive

Uml-unified Model Language Unified Modeling Language, also known as standard modeling language. is a language used to visualize modeling software-intensive systems.There are three main models in UML system development:Functional Model: Display the function of the system from the user's point of view, including use case diagram.Object model: Using the concepts of

software components that will run on their systems. Although the system administrator will not be able to identify physical devices or things from the graphBut they still welcome the component diagram because it provided earlier information about the component and its relationship (which promised the system administrator to easily plan the subsequent work ).SymbolCurrently, the component

Significant progress has been made in serialization logic modeling due to changes in the symbol set of the sequence diagram in UML 2 ).Note the text I mentioned above: "The uml2.0 draft Specification has been adopted ."

Administrators can find component diagrams useful because they can get an early view of logical software components that will run on their systems. Although the system administrator will not be able to identify physical devices or physical executable programs from the graph, they still welcome the component diagram, because it provides information about components and their relationships earlier (this allo

Through the previous blog: the use case diagram of UML diagrams, we have completed the division of a software system use case and function module. Now we need to know how to further improve the static structure of the system. With the UML tool, we can obtain the static diagram
