PowerDesigner object-oriented model (OOM) Description

1. OOM Introduction

Object-OrientedModel (OOM) object-oriented model. An OOM contains a series of packages, classes, interfaces, and their relationships. These objects form a class structure of all (or part) the logic of a software system design view. An OOM is essentially a static conceptual model of a software system.

(1) use UML to describe the system structure

(2) generate source files (such as Java, C #, and PowerBuilder) in different languages using class diagrams, or convert source files of different types into corresponding class diagrams using reverse engineering.

1.1 create OOM

(1) Select File> New Model Menu item

(2) Select "Object-Oriented Model" (object-oriented Model) in "Model type" on the left)

(3) enter the model name on the right and select the language.

(4) Select a type

1.2 design example Diagram

(1) define Use Cases

(2) Define roles

(3) define Association

1.3 design sequence diagram

(1) Define roles

(2) define an object

(3) define a message

(4) define the activation period

1.4 design class diagram

(1) define a class

(2) define attributes

(3) define the identifier

(4) define operations

(5) define interfaces

(6) create a contact

1) join

2) Dependency

3) Generalization

4) Implementation

1.5 generate code

(1) Select Language → Generate Java Code

(2) Select a class

(3) set generation options

(4) generate code

(5) view the generated code

Ii. Example 2.1 create OOM

File --> new model

 

Here we select the OOM type to use the default Class digoal, and the language is Java.

 

2.2 OOM generates Java code

Create a class through the tool Panel, such:

 

Double-click a class to edit related attributes.

 

Add variables to the class:

 

 

If we want to add a method to the class:

 

 

First, write the method name and return type of the method, and then click the second step to modify the corresponding attributes of the method:

 

Content of the modification method:

The method name cannot be modified. In this step, we can only modify the code corresponding to the method.

 

To add parameters to a method:

 

After the configuration is complete:
