The following sections describe the components of a CA Ideal™ for CA Datacom® application.
A dataview is a logical view of data that lets you make requests of the data independently of the storage structure.
Dataview definitions for accessing CA Datacom®/DB tables using native command access are created and maintained in the Datadictionary.
CA Ideal™ for CA Datacom® maintains dataview definitions for SQL access, both for CA Datacom®/DB objects and DB2 objects, in the dictionary facility. The CA Datacom®/DB tables, views, and synonyms are created and maintained in the Datadictionary. The DB2 tables and views are created and maintained in the DB2 catalog.
There are two types of dataview definitions for sequential files:
CA Ideal™ for CA Datacom® treats modeled and unmodeled dataview definitions for sequential files identically once they are cataloged.
Like dataview definitions for unmodeled sequential files, dataview definitions for VSAM files are created and maintained in the Virtual Library System (VLS) and the dictionary facility.
Several facilities are provided for defining a CA Ideal™ for CA Datacom® program:
Program definitions are maintained using the Program Definition Facility. For complete information on the program definition panels, see Creating Programs. For more information about descriptions of PDL statements and functions, Using Procedure Definition Language.
The CA Ideal™ for CA Datacom® Panel Definition Facility (PDF) provides the facilities for creating and maintaining panel definitions that transmit data between the user and the application program. After they are created, you can print, test, and edit panel layouts and definitions online for immediate use. For information about defining panels, see Creating Panel Definitions.
The CA Ideal™ for CA Datacom® Report Definition Facility (RDF) creates, maintains, and tests report definitions. RDF lets the CA Ideal™ for CA Datacom® user define online each report's layout, parameters, fields, column headings, and other options. For information about defining report layouts, see Generating Reports.
CA Ideal™ for CA Datacom® provides a mechanism for defining and generating XML and HTML documents, either in batch or online in response to an HTTP request. For more information about defining documents, see Generating Documents.
CA Ideal™ for CA Datacom® provides a means for creating, maintaining, and binding plans for DB2 applications. See Preparing DB2 Application Plans.
