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

The knowledge of UML has been learned for a while, and the understanding of the nine types of diagrams has changed a lot since I did not understand it before. The viewpoint on pure theoretical knowledge of software engineering has also changed, it tastes a little bit better. In my opinion, the nine diagrams of UML are different understandings of a system at different stages or from different angles. In fac

The three "allies" James Rumbaugh, Grady booch, and Ivar Jacobson created UML in 1995 and integrated their respective methods (OMT, booch development method, and OOSE) into a whole. In 1997, OMG used UML as an actual public standard. To a large extent, UML is a graphical language used to describe, record, design, and construct a solution. The powerful role of

In the process of learning UML class diagram, UML class diagram relation is a problem that must be mastered, and there are six kinds of relationships in UML definition: dependency, genus, association, implementation, aggregation and combination. The definitions and representations of the methods are described below.Introduction to

Introduction Some time ago and a friend on MSN Chat to UML, he sighed: "Know that UML is a good thing but not use it." Have tried, the results of leadership requirements in the document to fully use UML, everything is UML, the results of a simple design document added a bunch of diagrams. At the time of the review, th

In this article, I will discuss the structure diagram, which is a new graph type that has been proposed in UML 2. Since the purpose of this series of articles is to help people understand the mark elements and their meanings, this article mainly involves class diagrams. You wil

all. beyond this, the tool has some promise. the only other complaint I really have is the install experience. there are some odd dependencies that aren't encoded in the installer, so you have to go hunt them down and install them separately.
