It uses the "lifeline" of objects and the messages passed between them to show how objects participate in interaction. A sequence

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 to show the structure and foundation of the system, including class

COM program code run Agent execution map Brief introduction Component diagrams, also known as building diagrams, are used to display physical views of the system's components and the relationship of each component. Component diagrams typically include components, interfaces, relationships, ports, and connectors to display dependencies and generalization relationships between corresponding modules, source files, or collections of source files in program code.

Introduction of Timing Diagram (Brief introduction) time series diagrams (Sequence Diagram) are graphs that display the interaction between objects, which are arranged chronologically. The sequence diagram shows the sequence of message interactions between the objects participating in the interaction and their objects. The modeling elements included in the time s

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 description. To better illustrate how our sy

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.

PrefaceIn the summary of the UML state diagram, the activity diagram and the state diagram are closely related. It also has a lot in common with flowcharts.definitionAn activity diagram is a special form of a state diagram. All or most of these states are active, and all or

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 of the static structure of the software system. The static diagram includes the class

1. What is a sequence diagram is an interaction diagram that emphasizes the time order of messages. A sequence diagram describes the interaction between classes and classes in a class system, and it models these interactions as message exchanges. A sequence diagram is a model that describes how objects collaborate over

First, time series diagramThe time series diagram is an interaction diagram that emphasizes the chronological order, in which the objects participating in the interaction are first placed above the graph and arranged along the x-axis. Usually the object that initiates the interaction is placed on the left, the lower object is placed on the right, and then the messages sent and received by these objects are

Example: (1) There is a DFD diagram below, where the interval between the vertical dotted line input, transformation, and output, Please convert it into a SC diagram: Solution: we can see from the figure that the left side of the first vertical dotted line is the input part, the center is the transformation part, and the edge is the output part. As a result, we can know that the level-1 SC

The state diagram is one of the diagrams of modeling the dynamic aspects of the system in UML, which describes the dynamic behavior of object state over time by establishing the life cycle model of the object. The state of an object in the system is easiest to discover and understand, so the first thing to consider is the flow of control based on the state. Specifically, a state diagram is used to describe
