PowerDesigner UML Introduction (Part II) Author: Sybase, Inc. powerdesigner product manager David Dichmann In the BluePrint #4 (an electronic version of access to Http://www.sybase.com/blueprint for previous issues), we explored 5 UML diagrams: Use case diagrams, Sequence diagrams, activity diagrams, class diagrams, and component diagrams to help you master the requirements of your system, Design its physi

Green is a plug-in for Eclipse, an advanced and simple UML Class diagram tool that major students develop and use. It is the live round-tripping editor, so it's easy to generate Java code from a UML class diagram. It has a good scalability. Green is the live round-tripping editor, which means it supports both software engineering and reverse engineering technology. You can use it to create a

Preface In Ooa and Ood, UML has been widely used in system analysis and design. In UML's 9 kinds of graphs, the class diagram is one of the most important and most commonly used graphs. However, in the chat with some friends, especially beginners, I found that many friends have some misunderstandings and puzzles about the function and the method of using the class diagram. So I wrote this article, I hope this article to some extent to help these frien

UML is used to model the system, it can be applied to a wide range, can describe many types of systems. The goal of UML is to describe any type of system in an object-oriented way, most directly using UML to create a model for a software system. But UML can also be used to describe other systems that are not computer s

first, the basic concept UML as a unified Modeling language, is a model of language, then the model is mainly used to represent, this time naturally generated UML diagram. UML mainly consists of basic building blocks, rules and public mechanisms, in which the basic building blocks consist of things, relationships and graphs. II. Basic Structure Diagram is an imp

· UML goals The development of UML has multiple goals. First, the most important goal is to make UML a general modeling language available for all modelers. It is not someone's proprietary, and is based on the general consent of the computer industry, that is, it includes a variety of major methods and can be used as their modeling language. At least, we wan
