PowerDesigner Overview

• Why Modeling?
• PowerDesigner History
• PowerDesigner Features Summary

4
Why Modeling? An analogy
Would you build a house without a blueprint ?
The Architect validatesthe concept with the
client From these drawings, a technical diagram
will be derived
The Contractors will take this blueprint and
optimise it based on technical considerations
linked to the Architectural View
5
The Application Development Process
A Business Process Model describing the Software
Development Lifecycle

• Starts with Understanding Business Needs
• IT Manager then
• Matches business needs with Technological
  Requirements
• Manages the IT development team a
  multi-discipline team
• Most IT shops separate DB development from
  Application development
• Specific tools needed for each population/role

PowerDesigner 9.5.2 for PowerBuilder

• PowerDesigner for PowerBuilder Features Summary
• PowerBuilder Applications Design and Development
• Reverse Engineering PowerBuilder Applications
• Designing PowerBuilder Applications
• Generating PowerBuilder Applications
• Extending PowerDesigner Features
• Future Direction

13
PowerDesigner for PowerBuilder Features Summary

• PowerDesigner 9.5.2 introduces complete support
  for all PowerBuilder objects reverse engineering
  and generation
• Support libraries (.pbl) and source files (.sr)
• Support PowerBuilder 6, 7, 8 and 9
• PowerBuilder tool palette for creating new
  objects
• Model verification
• Generate reverse PowerBuilder extended
  attributes in PDM

14
Problem Statement

• Most of PowerBuilder developers dont do design.
• Many PowerBuilder applications dont have a good
  architecture and there is no documentation.
• It is difficult to maintain and evolve when the
  developers are gone.

15
PowerDesigner Value Proposition

• Help users to understand how the application was
  developed.
• Help users to visually see the relationship
  between objects.
• Help users to improve existing code, refactor the
  code.
• Regenerate PowerBuilder application.
• Generate documentation (report) in HTML and RTF
  format.

16
Reverse Engineering PowerBuilder Applications

• Application, User Object, Structure, Function,
  Window, Proxy are represented by class structure
• For the other objects (DataWindow, Query,
  Pipeline, ), the source code is preserved and
  can be regenerated
• Both libraries (.pbl) and source files (.sr) can
  be reverse engineered

17
Reverse Engineering PowerBuilder Applications

• You could select reverse engineering options.
• You could use PowerBuilder System Classes and PFC
  library models to represent parent classes that
  give you the complete definition of the System
  Classes.

18
Displaying PowerBuilder Objects in Class Diagram

• A class diagram shows packages, inheritances,
  associations, dependencies, attributes,
  operations.
• Each library is represented by a package.
• A stereotype and a mini icon shows the type of
  object.
• The dependencies show which menu or data window
  is used by which window.
• Window, user object, application, structure,
  function and proxy are represented as classes and
  the code is regenerated from the class
  definition.
• Other objects are represented as classes by the
  source code is kept and are not regenerated from
  the class definition.
• Controls are represented by inner classes.

19
Example of a Class Diagram
20
Designing PowerBuilder Applications

• You can create, modify or delete objects or
  links.
• You can use the PowerBuilder tool palette to
  create objects.
• You could define interfaces and implement
  interfaces but the interfaces will not be
  generated.
• You can preview the PowerBuilder code.
• You can modify the PowerBuilder code in the code
  preview window.
• You can write specification in RTF format. You
  could use Word to edit the description or
  annotation.
• You can generate reports in HTML or RTF formats
  for documentation.

21
Defining Inheritances

• A parent class could be a shortcut representing a
  class defined in another model for example for
  system classes.

22
Defining Events

• Events are represented as operations.
• An Event could be an operation with the event
  stereotype, with a language event or with an
  extended attribute EventID (pbm_).

23
Overriding Properties

• In the Attributes tab of the class property
  sheet, the Inherited button allows you to select
  the properties to override.

24
Previewing PowerBuilder Code

• Open the properties of an object. Select the
  Preview tab.
• For Window, User Object, Application, Structure,
  Function and Proxy, the code is generated from
  the class definition. You could change the code
  in the Preview window (add attributes, modify
  operations, ), the model will be updated to
  reflect the changes.
• For DataWindow, Menu, Query, , you could change
  the code in the Script tab

25
Verifying the Model

• You could use the Check Model function to verify
  if the model is well defined.
• There are PowerBuilder specific checks.

26
Generating PowerBuilder Applications

• You can generate PowerBuilder objects into
  libraries or source files.
• You can select the objects you want to generate.

27
Extending PowerDesigner Features

• You could use various extensibility features of
  PowerDesigner to extend PowerDesigners
  PowerBuilder generation and reverse engineering
  capabilities
• Profile
• GTL (template based code generator)
• VBScript, OLE automation (PowerBuilder, .NET,
  Java, C, )
• Plugins

28
Future Direction

• PowerDesigner 10.0 will support tight integration
  with PowerBuilder 10
• PowerBuilder 10 will be able to embed
  PowerDesigner views inside PowerBuilder
• PowerBuilder will be able to control
  PowerDesigner
• PowerDesigner will generate complete PowerBuilder
  application code (post 10.0)

29
PowerDesigner Roadmap

  Target Context Menu
• Select PBLs and Objects to Reverse Engineer

37
PowerDesigner and PowerBuilder Together
Design and Generate PowerBuilder Code Using
PowerDesigner

• Create a New PowerBuilder OOM (Object Oriented
  Model)
• OOM name maps to PowerBuilder target name
• Package name maps to PowerBuilder pbl name

38
PowerDesigner and PowerBuilder Together
Design and Generate PowerBuilder Code Using
PowerDesigner

• Add Classes and Do Design
• Although PowerBuilder doesnt support interface
  yet, user can define interface in PowerDesigner,
  then implement interface in a PowerBuilder user
  object.

39
PowerDesigner and PowerBuilder Together
Design and Generate PowerBuilder Code Using
PowerDesigner

• Check Model
• Check model is customized for PowerBuilder, for
  example, it will check whether a object name is
  valid PowerBuilder name, a pbl can only have one
  application object
• Check model results are printed in output window

40
PowerDesigner and PowerBuilder Together
Design and Generate PowerBuilder Code Using
PowerDesigner

• Generate PowerBuilder Code
• Select packages and classes from OOM to generate
  PowerBuilder code
• If it is the first time to generate PowerBuilder
  code, a new PowerBuilder target will be created

41
PowerDesigner and PowerBuilder Together
Navigation Between PowerDesigner and PowerBuilder

• From PowerBuilder to PowerDesigner
• Select Open Class Diagram from pbl context menu
  to open class diagram for this pbl
• Select Find in Class Diagram from PB object
  context menu to find the corresponding class in
  class diagram
• From PowerDesigner to PowerBuilder
• Double click a class in class diagram to launch
  PowerBuilder painter to open corresponding PB
  object
• Select Find in PowerBuilder Workspace from
  class context menu to find the corresponding
  PowerBuilder object in PowerBuilder workspace
