13. 13© 2005 Progress Software Corporation DEV-07: Increasing Productivity with Tools for Business Logic How the Designers Work Overview of Designer Elements Model Definition Visual Designer Code Catalog Data Schema Code Generation Abstract Syntax Tree (AST) 1 N N

14. 14© 2005 Progress Software Corporation DEV-07: Increasing Productivity with Tools for Business Logic Catalog-Oriented n Store and index application metadata eg –Code annotations –Cross-reference data –Define your own! n Simplifies management and organization of components n Some components will be cataloged automatically by the IDE n Can be created and managed independent of the IDE n Rebuild on demand – therefore not a repository Catalog

16. 16© 2005 Progress Software Corporation DEV-07: Increasing Productivity with Tools for Business Logic Annotation-Oriented n Annotations describe code elements n Used by tools for business logic designers to implement Code/Model approach n Stored and organized in the Catalog n Define your own annotations –Bug tracking, packaging etc. @module(name=“AR”) @ads-link(type=“dataset”,name=“order”) @

18. 18© 2005 Progress Software Corporation DEV-07: Increasing Productivity with Tools for Business Logic Tools for Business Logic – Visual Designers Outline View for Code and Schemas Text Editors: (4GL, WebSpeed, XML, SQL) Visual Editors: (Model, Schemas) Create components from templates Resource, Catalog & Component Explorers

19. 19© 2005 Progress Software Corporation DEV-07: Increasing Productivity with Tools for Business Logic XML Designer The Schema Designer n The centerpiece of the tools for business logic –Most data-oriented objects have schema that needs to be created and manipulated Data Set Designer GraphTreeCode n Operates like an ERD tool and is used to create Application Data Schemas (ADS)

21. 21© 2005 Progress Software Corporation DEV-07: Increasing Productivity with Tools for Business Logic Data Source Mapping n 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 n The DSM operates in a simple grid format –More complicated “wiring” mode to be added later Logical Table Logical Field Physical Table Physical Field L_CustomerCustomerNumCustomerCustNum L_CustomerCustomerName … L_CustomerCustomerCityCustomerCity

22. 22© 2005 Progress Software Corporation DEV-07: Increasing Productivity with Tools for Business Logic Data Source Mapping n Design-time output is XML –Field pairs in an XML document n Runtime implementation is: –Code - DataSource (4GL) –A procedure who’s output is of type DataSource

23. 23© 2005 Progress Software Corporation DEV-07: Increasing Productivity with Tools for Business Logic Data Access Object Designer n The Data Access Object Designer (DAO) is used for designing specific fill and update functionality for the source it’s attached to n The design-time output is code n The runtime implementation is code

24. 24© 2005 Progress Software Corporation DEV-07: Increasing Productivity with Tools for Business Logic Business Entity Designer n Add business related processing to data elements n Coordinate the interaction between DAO & Data Schema elements through code n Visual canvas similar to modeling tools
