Object-oriented software development methods include: A, object-oriented analysis (OOA) B, object-oriented design (OOD) C, object-oriented implementation (00i) d, the main steps of object-oriented testing (OOT), E, and object-oriented maintenance (OOM) are as follows. Next we will learn the related diagrams of UML from the object-oriented perspective. This section describes the use case diagram and Activity
Through the static diagram and behavior diagram introduced in previous blogs, we can use UML to describe the static structure and dynamic behavior of a system. At this time, we have alreadyGraphical representation of the entire structure of a typical Surface-to-face object system.
At this point, the software development stage has reached the implementation s

The basis of software requirement analysis: the model analysis method.
The structured analysis method is applicable to the demand analysis of data processing software. It provides the following modeling tools: data flow diagram, data dictionary, machine learning English language, decision table, and decision tree.

2. role: it is easy to understand complex systems and control the connections between various parts of the system structure. Logically, you can modularize a complex diagram
Use case diagram is used in the requirement Analysis stage, describes the functional requirements of a system to be developed, the use Case view emphasizes the function of the system, and is the first design view of the software development design process. It describes the user's snowball from the user's point of view, describing the function of the system, and pointing out the performer of each function an
PLC uses a ladder chart language that is extremely similar to the circuit diagram of the relay. If PLC is used to transform the relay control system, it is a shortcut to design a ladder chart based on the relay circuit diagram. This is because the original relay control system has been used and tested for a long time and has been proved to be able to complete the control functions required by the system. Th
Various diagrams in UML are an important part of the UML model. In recent articles, I will introduce nine important diagrams in UML. The general content is shown in the following directory.
1. use case diagram, class diagram, and object Diagram
2. Sequence diagram and collaboration

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

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
