1. emergence of standard modeling language UML The accepted object-oriented modeling language appeared in the middle of 1970s. From 1989 to 1994, the number has increased from 10 to more than 50. Among the many modeling languages, language creators strive to promote their own products and improve them in practice. How

The development of Object-Oriented Analysis and Design (OOA D) methods has seen a climax from the end of 1980s to the end of 1990s. UML is the product of this climax. It not only unifies the Expression Methods of booch, Rumbaugh, and Jacob, but also makes further development on it, and finally unified it into the standard modeling language accepted by the masses. 1. emergence of standard

a thing in the UML Some of the basic graphic symbols that make up the model diagram, which represent some basic object-oriented concepts.There are four kinds of things in UML structural things (structural things), behavioral things (behavioral things), group things (grouping things),Annotational Things (note things). Two four types of things in UML (things) (1)

UML Modeling Tools Comparison of Visio, Rational Rose, powerdesignThe most widely used by two of various 1. Rational Rose, it's IBM's. Microsoft Office visio®2003 3.Enterprise Architect for 2.Microsoft. There are other tools such as PowerDesigner, etc.1.Rational Rose is a UML-based modeling

provides the standard for system modeling. These graphical symbols and literals express the application-level model, which is semantically an instance of the UML Metamodel. uml precise meta-model definitions and simple and uniform symbolic representations have also become a reason for their widespread adoption. The main content of UML:It shows the classification

status ﹑ even the creation and modification date of each subsystem. Because this is the information for the process, it is not a basic part of UML, although you can keep this information by adding tag values. In addition, this information is not a property of a class. The version number of a subsystem is part of its metadata, not part of the model. Figure 6-10 shows three subsystems, each of the which have been extended with the ? versioned ? stereot

This article mainly sorts out the UML modeling tool Visual Paradigm (VP-UML) official FAQ, hope to be helpful to visual paradigm users. Can the persistent layer generated in the VP-UML be redistributed? Does VP-UML support g

Since the formal release of UML in 1997, a large number of commercial UML modeling CASE tools have appeared. This provides us with a lot of options and requires us to select the correct UML modeling tool to better adapt to our bus

Comparison of UML modeling tools Visio, Rational Rose, and powerdesignRose is a design tool born directly from the Development of UML. It was designed to support UML modeling. Rose did not support database

just a tool for understanding and analyzing the system structure. It was difficult to establish a simple and correct model to consider the coding problem too early. The UML model can also be used as a basis for testing. Systems usually need to undergo unit testing, integration testing, system testing, and acceptance testing. Different test teams use different UML
