Functional overview Functional overview PowerDesigner Object-Oriented Model is a powerful design tool for object- oriented modeling. It gives you all the advantages of a graphical object design implementation. With this product, you can: ♦ Build an Object-Oriented Model (OOM) ♦ Generate Java class source files (.java) ♦ Generate PowerBuilder objects ♦ Reverse engineer Java files (.class, .java, or .jar) ♦ Reverse engineer PowerBuilder objects ♦ Import a Conceptual Data Model (CDM) ♦ Import a Phy

Chapter 1 Object-Oriented Model Basics UML and object-oriented modeling What is UML? UML (The Unified Modeling Language) is a modeling language aimed at defining standards for object-oriented modeling. UML has become a standardized language largely through the work of the OMG (Object Management Group), a group composed of individuals and representatives of companies involved in object-oriented projects. However, its original conception drew much of its inspiration from the work of G. Booch, J

What is an OOM? What is an OOM? An OOM contains a set of packages, classes, interfaces, and their relationships. These objects together form a class structure that is the logical design view of all (or part of) a software system. An OOM is essentially a static conceptual model of a software system. You use PowerDesigner Object-Oriented Model to build object-oriented models (OOM). You can build an OOM for purely object-oriented modeling purposes, to generate Java files or for PowerBuilder, or you

Chapter 1 Object-Oriented Model Basics Objects in an OOM An OOM represents the interaction of the following objects: Selection Object Tool Description Package General purpose sub-set used to organize objects into groups Class Set of objects that share the same attributes, operations, methods, and relationships Interface Collection of operations used to specify the externally visible behavior of a class, object, or other entity Attribute — Named property of a class Operation — Service that can

Creating a new OOM Creating a new OOM Creating an OOM requires that you do the following: ♦ Open a new file ♦ Give the OOM a name and a code After you create an OOM, you can enrich its definition by entering properties and associating objects. To create an OOM: 1 Select File➤ New. or Click the New button in the toolbar. The New window appears. 2 Select Object-Oriented Model and click OK. The Choose Object Language window appears. Every OOM is attached by default to one set of object language p

Chapter 1 Object-Oriented Model Basics Defining OOM model options You can set model options and naming conventions that apply to all objects in the model. You can also set naming conventions for each type of object in your model. You define OOM model options from the model options dialog box. You can set options that apply to the following OOM objects: ♦ Classes ♦ Default data types ♦ Domain/Attribute Classes You can set the following option for classes in an OOM: Option Description Show clas

Defining OOM model options Your choice of whether or not to enforce domain and attribute non- divergence has the following results: Non-divergence Result Not enforced Attributes that are divergent from the domain definition can remain attached to the domain Enforced Attributes that are divergent from the domain (for certain attribute properties) must be detached from the domain If you modify domain non-divergence options, these changes apply only to the current OOM.
