1. Power Designer
Sybase

2. Introduction
SAP Sybase PowerDesigner is the industry-leading business process / data modeling software and metadata management solution for data architecture, information architecture and enterprise architecture.
It is a CASE tool used for designing different models
It stores data about data

3. Four D’s of data The meta data is used for:
Discover – What is known about data
Document – define data models
Design/describe – may use for data movements and data descriptions
Do – finally creates the real artifacts from the model

4. Useful for Data Modeling Information Architecture
Enterprise Architecture

5. Structured as
A global generator

6. Why not use any drawing tool
Drawing tools communicate ideas visually and may also capture some additional information about some of the objects represented
Each diagram stands alone: If any process appears at various places, there is no connection between those symbols and there is no linkages or connection with the actual existence of these processes
i.e. there is no way of managing metadata

7. Power Designer Components
There are various components:
Models
Diagrams
Objects
Sub-Objects
Links
Examples etc.

8. Symbols The symbols are actually the objects
The links between the objects are also the symbols
For some things, there are no symbols, may not be used

9. Used For Create and manage artifacts like XML and DB Refactoring
Linkings
Collaborations
Communications
Documentations etc.

10. Data Modelling Sybase is used for defining CDM (Conceptual Data Model)
The CDM is independent of any underlined database
All the design issues of the data are defined here
Through the simple procedures, the CDM may be transformed into PDM (Physical Data Model)

11. Power Designer
Tools

12. Create CDM Steps are: DO NOT DEFINE THE FOREIGN KEYS IN THE TABLES
Start PowerDesigner
Use the tools from the tool palette
Define entities and relationships
Save it as .CDM
DO NOT DEFINE THE FOREIGN KEYS IN THE TABLES
From CDM, logical data model may be created
