best visio diagrams

How Visio can reverse-connect a database to generate an ER diagram (that is, automatically generate ER diagrams from a database) In the use of the author, there is an automatic generation of ER graph requirements. After a while, there are ready-made tools to do it. Now share with you: This article takes IBM DB2 as an example to generate ER diagrams. All other d

the participant, it can be considered a generalization relationship. The generalization relation is the inheritance relation between the general class and the special class. Cars and ships, for example, have a generalized relationship with transportation. They belong to the same means of transport, with their own characteristics.Use cases and use cases: there are generally generalizations, inclusions (uses), and extensions.Use case generalization: a use case can be specifically enumerated as on

brand is not the same, we can only use the following method to establish a network topology diagram, that is, hand-drawn. VISIO2003 is the best in hand-drawn tools, and he is a professional drawing tool produced by Microsoft, through which he can draw dozens of charts, including network topology, network structure, architectural drawings, mechanical engineering diagrams, maps, The simple and easy-to-use features of the Office family are also inheri

The key to the processing of object-oriented problem is the modeling problem. Modeling can abstract many important details in a complex world. Many modeling tools encapsulate UML (that is, unified modeling language™), a course designed to showcase the highlights of UML. UML has nine modeling icons, namely: Use case diagram Class Diagram object graph order diagram Collaboration diagram state diagram activity diagram Component Diagram configuration diagram Some sections of this course contain a pa

Machine Room reconstruction Drawing is a very important stage, the machine room is reconstructed before also painted UML diagram, but this time and the last time, this time have layered thinking inside.Package DiagramBefore the three layers of the time between the transmission is clear, package diagrams is also easy to draw out, first look at the previous three layers of package diagram. The input information is passed from the U layer to the B layer

management of databases and database iteration are not very good. Powerdesigner was originally a database modeling tool developed for database modeling. It was not until version 7.0 that it began to support object-oriented development, and later introduced support for UML. However, because powerdesigner focuses on different aspects, it supports database modeling well and supports about 90% of the databases that can be seen. The support for various diagrams
