2
Compare and Merge Models
• The model merge window is used when generating model,
generating database, reverse engineer database, consolidate
model in repository, …

Model-Driven Architecture (MDA)
 Model-Driven Architecture (MDA) is defined by OMG
 Main ideas:
 Separating specification with implementation
 Specifying a system that is independent of a platform
 Transforming a platform independent system specification into
a specific platform
 Code generation

Report Generation
• Generate complete report in HTML, RTF formats
• Support English, French, Chinese, …
6
Repository
• PowerDesigner has an enterprise repository for model
sharing and versioning
– Consolidation/Extraction of Models and other nonPowerDesigner files
– Object level versioning
– Branching, Configuration
– Security
– Comparing versions
– Use relational database
7
Profile (Extended Model Definition)
•
•
•
•
•
Similar to UML Profile; applies to all models
Can be used to extend an existing model type
Stereotype and criteria
Extended attributes, objects and collections
Code generation templates
– Generation Template Language (templates & macros)
•
•
•
•
Custom symbols
Custom tool palette
Custom checks
Custpom popup menus
8
Code Generation
• Code generation templates
– Generation Template Language (templates & macros)
• All PowerDesigner code generators are defined as templates (Java, C#, VB
.NET, PB, ebXML, BPEL4WS, SQL, XML, …)
• You could modify existing code generation or define your own code
generation
9
VBScript
• You can use VBScript to control PowerDesigner (query
objects attributes and collections, create objects,
import/export models, generate code, generate reports,
…)
• You can define menu items to launch VBScripts
• You can use VBScripts to define model transformation
• You can use VBScripts to define Design Patterns
• There is a VB Script samples directory
10
OLE Automation
• OLE automation can be used by a program outside of
PowerDesigner
• You can use any language (VB, VBA, VB .NET, C#, PB,
C++, JavaScript, Java, …) that supports COM to work
with PowerDesigner
• You can create your own user-interface
• There is an OLE automation samples directory
