Why Modeling? PowerDesigner History PowerDesigner Features Summary

Why Modeling? – An analogy

The Architect validatesthe concept with the clientFrom 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

Would you build a house without a blueprint ?

The Application Development Process

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

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

Problem Statement

Most of PowerBuilder developers don’t do design. Many PowerBuilder applications don’t have a good

architecture and there is no documentation. It is difficult to maintain and evolve when the developers are

gone.

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.

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

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.

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.

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.

Defining Inheritances

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

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_*).

Overriding Properties

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

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

Verifying the Model

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

Generating PowerBuilder Applications

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

Extending PowerDesigner Features

You could use various extensibility features of PowerDesigner to extend PowerDesigner’s PowerBuilder generation and reverse engineering capabilities:

Profile GTL (template based code generator) VBScript, OLE automation (PowerBuilder, .NET, Java, C++, …) Plugins

The profile concept

PowerDesigner uses the profile concept to extend/cutomize the definition of its metamodel

Profiles are used for Creating categories of objects (stereotypes and criteria) Customizing the graphics of objects Adding additional metadata to objects (extended attributes) Defining new or modified generation capabilities (templates) Defining custom checks, menue-items, events, etc..

Profiles appear in all DBMS, object languages and extended model definitions

Profiles appear in all DBMS, object languages and extended model definitions

GTL – Generation Template Language

Easy to use template language Mixes generated text with object properties enclosed in %

characters Provides macros for

Specifying conditional logic Iterating on object collections Manipulating text

VB Scripts may be embedded in GTL templates for complex logic

Supports inheritance and polymorphism

GTL – Generation Template Language

Sample:

Class %code% {%attributes%

}

.foreach_item(Attributes).if (%visibility% == +)

public %DataType% %Code%;.elseif (%visibility% == -)

.//....endif

.next(\n)

MacroCollection

Variable

VBScript

Manipulate PowerDesigner objects in memory and perform any action on them

Browse object collections from the model down to any object using PowerDesigner`s metamodel

You can Load and save models Gain access to object definitions Perform checks Change object property values Create or delete objects with the wanted characteristics

OLE automation

VBScript allows you to write a VBScript and execute it inside PowerDesigner to manipulate PowerDesigner objects

OLE automation allows you to write a program to manipulate PowerDesigner objects from outside

You can use any programming language that supports COM to access PowerDesigner objects, create user-interfaces, integrate PowerDesigner functions in your program, etc...

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)

PowerDesigner Roadmap

PowerDesigner Athena (V10, December 2003) Integration with PowerBuilder Integration with Eclipse (Q1 2004) Major BPM improvements XML model Fully support MDA

PowerDesigner Minerva (end of 2004) Enterprise features (requirements, impact analysis, …) XML and Web Services in database UML 2.0 Design patterns

Business Process Modeling Improvements

Add targets (Analysis, BPEL4WS , ebXML, Integration Orchestrator, MessageBroker, …)

Support simulation (use Simul8 engine) Support Service-Oriented modeling Model, generate & reverse BPEL4WS Better integration with Integration Orchestrator (round-trip) Better support ebXML BPSS
