Powerdesigner supports all uml1.3 charts, including use case charts, sequence charts and class charts, activity charts, and component charts, and fully supports uml2.0. Improved Object-Oriented Analysis and Design (OOAD) analysis methods and enhanced integration with the development p

Why modeling? One basic reason is that modeling aims to better understand the system being developed.
Through modeling, we need to achieve four goals:
(1) The model helps to visualize the system based on the actual situation or the

Enterprise Architect (EA) is an OMG UML-based visual model and design tool that provides support for the design and construction of software systems, business process modeling, and domain-based modeling, and is not only used by enterprises and organizations to model systems, It is also used for propulsion models to be implemented throughout the application develo
Today, we continue to learn about the static and dynamic modeling of UML, we hope that you will learn more about UML modeling over the past two days and apply it in future project development.

There are several important concepts that must be understood before you begin to describe UML. These are very important concepts hidden in UML. However, these concepts are hard to understand. The reason for not using UML is that they do not know where to use and how to use them. In essence, they are not understood. The following describes these concepts one by on

(5) Identify all entry or exit actions.
(6) If necessary, you can use sub-States to expand these states. Organize and simplify a complex state machine using concepts such as hyperstate, substate, branch, and historical state
(7) check whether all events involved in the state machine match the expected events in the object interface.
(8) check whether all the actions involved in the state machine are supported
(i) UML Overview1, object-oriented software development process:(1) OOA (object-oriented analysis): Establish an analytical model and document it. (2) OOD (object oriented design): The result of OOA is refined by object-oriented thought, and the design model is obtained. (3) OOP (object-oriented programming)2, UML is the results of OOA and ood with a unified symbol to describe and record. 3,

The UML use case diagram contains three relationships: (include), (extend), and (generalization ).
Overview
The Use Case attempts to summarize the relationship between roles and systems in the use case, and describes the functional requirements of the system, the interaction between roles and systems, and the system response.
Official definition: Use Cases define a set of use cases, each of which is a series of operations perfo

Modeling principles;(1), choose what model to create, have a profound impact on how to solve the problem and how to form a solution(2), each model can be represented at different levels of accuracyIn any case, th

These and many other features can be expressed in UML, but they belong to a deeper concept.Dependencies, generalizations, and associations is all static things defined at the level of classes. In the UML, these relationships is usually v

Today I borrowed a concise tutorial on the Standard Object Modeling Language (UML Distilled: a brief guide to the standard Object Modeling Language ). Translated by Mr. Xu Jiafu. In general, I feel that a good book is ruined. Those in the beginning of this article are not in the same order. For example, "If someone accidentally falls into my trap and the Controll
