. 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 diagram There are four types of relat

can use class diagrams to model the business vision of the system. As we will see in this series of articles on the basics of UML, other diagrams-including activity diagrams, sequence diagrams, and state diagrams-reference class modeling and documentation in class diagrams.

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 object, attribute, operation and correlation

Summary :-- recommended reasons : Recently from the Windows operating system to the MAC, is looking at design patterns and refactoring, can not find good UML tools, so on the internet to find an online use of the UML tools, used to find it well, recommend to everyone;-- tool address : https://www.processon.com/;I. UML

the graph must follow the following format: Graph type graph name UML specifications provide specific text values for graph types. (For example, SD represents a sequence diagram, activity represents an activity diagram, and use case represents a use case

rectangle, and the actual UML diagram is defined inside a large closed rectangle. Figure 1: Empty UML 2 framework componentIn addition to providing a graphical border, framework components used in graphs also have important functions to describe interactions, such as sequence diagrams. In a sequence diagram, a sequenc

state again, it can go directly into the sub-state, rather than starting again from the initial state of the combined state.Concurrency ZoneA state diagram can be divided into regions, and regions include exits or sub-states that are currently executing. Indicates that the combined state can reach multiple sub-states at a time.State Machinedescribes the sequence of states that an object or an interaction undergoes in response to an event during its l

chronological and spatial order;(9) activity digraphs, which describe the activity of system elements; Based on their applications in different architecture views, nine types of graphs can be divided:(1) User Model View: use case diagram;(2) Structure Model View: class chart and object chart;(3) Behavior Model View: status chart, sequence chart, collaborati

. The state chart expresses the state machine, which is used to model the control flow from events to events. A state chart can indicate the history of an object, events that cause a state to be transferred to another State, and actions that result from state transfer.A state chart is suitable for describing the behavior of an object traversing multiple use cases, but a state chart is not suitable for describing the collaborative behavior of multiple objects.A state chart can be used to model an

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
