Chapter 3 Building Conceptual and Logical Diagrams
The data models in this chapter allow you to model the semantic and logical structure of your system.
PowerDesigner provides you with a highly flexible environment in which to model your data systems. You can begin with either a CDM (see Conceptual Diagram Basics) or an LDM (see Logical Diagram Basics) to analyze your system and then generate a PDM (see the Building Physical Diagrams chapter) to work out the details of your implementation. Full support for database reverse-engineering allows you to take existing data structures and analyze them at any level of abstraction.
For more information about intermodel generation, see "Generating Other Models from a Data Model" in the Working with Data Models chapter.
