What are Tools for Business Logic?

Visual design tools for the development of business objects– Business objects represent the data

elements and business logic code that provide application functionality

Included in the new OpenEdge™ IDE Supports the OpenEdge Reference

Architecture Support for custom Application Models

Code/Model Development

Visual/Graphically OrientedText/Code Oriented

Code-centric Model-centric

Code written by hand can easily be transformed into visual model components

Model components can be visually edited and the code

elements will reflect the change

Code/Model Development

Accommodate a wide range of development styles

Code can be created or edited at any time

Code is not dependent on a model

Code elements can be transformed into model elements at any time

Models can be disassociated from code at any time

Models create structure and code that can be edited

Catalog-Oriented

Store and index application metadata eg – Code annotations

– Cross-reference data

– Define your own! Simplifies management and organization of

components Some components will be cataloged automatically

by the IDE Can be created and managed independent of the IDE Rebuild on demand – therefore not a repository

Catalog

Annotation-Oriented

Annotations describe code elements

Used by tools for business logic designers to implement Code/Model approach

Stored and organized in the Catalog Define your own annotations

– Bug tracking, packaging etc.

Tools for Business Logic – Visual Designers

Outline View for Code and Schemas

Text Editors: (4GL, WebSpeed, XML, SQL)

Visual Editors: (Model, Schemas)

XML Designer

The Schema Designer

The centerpiece of the tools for business logic– Most data-oriented

objects have schema that needs to be created and manipulated

Data Set Designer

Graph Tree Code

Operates like an ERD tool and is used to create Application Data Schemas (ADS)

Data Source Mapping

Data Source Mapping (DSM) is used for connecting PDS to ADS– Table/Field pairs are loosely linked

– Attributes such as keys need an affordance

– Code could be entered for derived data

The DSM operates in a simple grid format– More complicated “wiring” mode to be added later

22 DEV-07: Increasing Productivity with Tools for Business Logic© 2005 Progress Software Corporation

Data Source Mapping

Design-time output is XML– Field pairs in an XML document

Runtime implementation is:– Code - DataSource (4GL)

– A procedure who’s output is of type DataSource

23 DEV-07: Increasing Productivity with Tools for Business Logic© 2005 Progress Software Corporation

Data Access Object Designer

The Data Access Object Designer (DAO) is used for designing specific fill and update functionality for the source it’s attached to

The design-time output is code The runtime implementation is code

24 DEV-07: Increasing Productivity with Tools for Business Logic© 2005 Progress Software Corporation

Business Entity Designer

Add business related processing to data elements

Coordinate the interaction between DAO & Data Schema elements through code

Visual canvas similar to modeling tools
