How CA Ideal Stores Application Components

Entries in the dictionary facility and VLS members for CA Ideal components are created at various times during the application development process.

The first CA Ideal entity-occurrences are stored in the dictionary facility when CA Ideal is installed. At that time, the first CA Ideal system and user are created, the appropriate entity-occurrences are added to the dictionary facility, the VLS source library, object library, and panel libraries are specified, and the appropriate relationships are created in the dictionary facility.

When additional users and systems are defined, CA Ideal adds other entries to the dictionary facility.

The database administrator defines modeled dataviews in the dictionary. In CA Ideal, the CATALOG DVW command reads the dictionary tables and creates an object module in the IDDVW VLS library.

Unmodeled dataviews

These are created in CA Ideal adding a source member to IDDVW and data to the dictionary facility. The CATALOG DVW command accesses the source member and the dictionary tables, and creates an object module in the IDDVW VLS library. Unmodeled dataviews can be created for sequential files and VSAM files.

CA Ideal data members are stored in the VLS library IDDAT. They are not modeled in the dictionary facility.

Panels and reports

Panels and reports are modeled in the dictionary facility and stored as VLS members. A dictionary entity-occurrence is created when the panel or report identification is entered. A single VLS member is added to the source library when the report parameter, header, detail, and column sections are created. This member contains all of these report components. A VLS member is added to the panel library for the panel layout, summary data, extended field definitions, input edit and validation rules, output edit rules, and facsimile. This member contains all of these panel components.

Programs

Programs are also modeled in the dictionary facility. An entity-occurrence is created in the dictionary when you enter the program identification. Relationship occurrences are added when you enter the program resource table. Separate VLS members are added to the source library for each program component. That is, members are added for the program parameter data, working data, and procedure. Each member is added when the corresponding component is first edited.
