Chapter 2 Introducing PowerDesigner
Data Analysts and Designers will map technical requirements to business requirements. Going deeper into the analysis, you can define Use Cases (using an OOM, see below), and map them to requirements. You can write functional specifications and define more precisely the nature and details of each process, the application and its data structure. You will use a BPM, and additionally a Conceptual Data Model (CDM), which is a platform-independent representation of a system, giving an abstract view of its static data structures. A PowerDesigner CDM permits real normalized data structures with many-to-many and super/sub-type relationships, and provides a clear view of business data across all systems, making system information accessible to business users, system architects, and business analysts.
