I recently looked at "Head first design mode", and in the previous blog I also mentioned this book, this is a very classic, very easy to understand the book, written very well. Because this book is described in Java, so I used the myeclipse wrote a bit of code, has been using Vs,vs to build UML diagram function is very powerful, now found MyEclipse can also build UML diagram, and the function is very powerf

IntroductionPowerDesigner supports all UML1.3 diagrams including use case diagrams, Sequence diagrams, class diagrams, activity diagrams, and component diagrams, and fully supports UML2.0. The object-oriented analysis and Design (OOAD) analysis method is improved and the integration with the development process is enhanced.PowerDesigner can help you build traditional business and e-business systems adapted to modern IT development, using new technologies such as Java, Object-oriented languages,

relationships between classes in UML diagrams: dependencies, generalizations, associations, aggregations, combinations, implementations turn from: http://blog.csdn.net/hguisu/article/details/7609483 classes and class diagrams1 Class (Class) encapsulates data and behavior, which is an important part of object-oriented, and it is the collective name of objects with the same attributes, operations, and relationships. 2 in the system, each class has a c

In learning to use UML to model the process, encountered a problem, that is, in the expression of the UML meta-class, "::" What does the colon mean. For example, Extend UML::D ependencies::abstraction, what does that mean. Is the use of namespaces. There is a lot of information, no definite answer. However, there are specific instructions in the official document

1. Preface The Design of functional modules is required for projects recently. The customer shall refer to the UML diagram for design materials. However, after so many years of dealing with the Japanese, I have forgotten what a UML diagram is and I have no choice but to check the materials from the beginning. So I made such a piece of information and told you how to learn

· UML Introduction Unified Modeling Language (UML) is a common visual modeling language used to describe, visualize, construct, and create software system products. It records the decisions and understanding of a system that must be constructed and can be used to understand, design, browse, configure, maintain, and control the system. UML is applicable to var

Modeling can abstract many important details in the complex world. Many modeling tools encapsulate UML (that is, the Unified Modeling Langu

-UML class diagrams are often used to describe the static structure between classes when describing the design mode. The purpose of this article is to allow the readers to understand the UML class diagrams and to figure out several relationships in the UML class diagrams. -In the subsequent design model learning process, only these two points are adequate. More a

In the past, I felt that I could not use UML. I didn't know what I was doing, that is, I knew there was a use case diagram, a class diagram, and a sequence diagram. At most, I wanted to express my needs, express the design to reach consensus. I recently worked on a project to know that UML is actually quite useful. From requirement to analysis, from analysis to design, from design to coding,

First, the nature of object-oriented abstract , when the system reaches beyond its processing power, we can abstract the scope we can deal with to commission abstract level , which allows you to build larger, more complex systems. 1, A way to map the real world to the object world. 2, A method of describing the real world from the object world. 3, A way to verify that the world behavior of an object reflects the real world correctly

When learning UML, you often encounter UML class diagrams. Here we will introduce the meaning of UML arrows and lines, I believe that you have a clearer understanding of the meanings of arrows and lines in UML through the introduction in this article. AD: This section describes the meanings of

It is difficult for many experienced designers to express a reasonable derivation process.There is a gap between the real world and the object world-this gap is called abstraction, and abstraction is the essence of object-oriented. It is also difficult. The difference between OO design masters and cainiao lies in abstract capabilities.F
