Most software developers know UML, but how can UML play a major role in software project development? The following describes the special features of different phases of the project. The special requirements of the situation refer to the use of UML. Application of

on the layer Provides a layout grid to help developers quickly locate and place symbols Provides a property editor for selecting nodes Supports serialization and loading and saving files in binary and SOAP formats Support for undo and redo operations Controls provide a variety of editing tools: alignment, layout, move, rotate, selection, text formatting, panning tools, stacking order Control provides a script editor that users use to define complex behaviors or actions Node labels

Today, we continue to learn about the static and dynamic modeling of UML, we hope that you will learn more about UML modeling over the past two days and apply it in future project development. Core UML chart Classification: ---> "Solitary nine swords"Static Modeling: [use case diagram], [class

The 13th chapter to the C # Programmer's UML overviewUML contains 3 main types of illustrations. Static diagram describes classes, objects, data structures, and their relationships, thus showing the unchanging logical structure between software elements. Dynamic diagram shows how a

UML is generally used in case-driven, architecture-centric, iterative, and incremental development. UML uses the following five views to describe the architecture of the software system: User Model View-use case diagram to describe system functions from the outside Structure Model View-class charts and object gr

A powerful UML auxiliary toolQuick sequence dimo-editorIt is specially used to draw sequence graphs. The key is free of charge. Advantages: The sequence digoal can be generated instantly by writing simple scripts. With the image export function (PNG, GIF, BMP, JPG, PDF, and other formats), and can adjust the image size, the image is also very clear. Can draw asynchronous operations and mark

what the customer needs is a ladder. What the system analyst understands is a stool. What the developer makes is a table. The tester thinks it is a chair, requirement analysis is a very difficult task! Although the demand analysis work is so challenging, it is also one of the charm of our software work! This course will be creatively used with you UML class diagra
