Bookshelf: About the DAC Subject Areas Tab

A subject area is a logical grouping of table groups that is related to a particular subject or application context.

The Subject Areas tab displays a list of subject areas in the top pane. This list includes the subject area name and an Inactive column, which indicates whether the subject area is active or inactive. Inactive subject areas do not participate in the ETL process.

Actions Available

The following actions are available in the top pane toolbar and in the right-click menu when the Subject Areas tab is active.

Preview Command

This command generates a preview of all tasks and their dependencies by reviewing the table groups, tables, and tasks. Information provided includes the approximate order in which tasks are executed, a list of source tables, target tables, and tables for which an image will be built. The preview will include all tasks regardless of the source or target. Unlike the preview generated from the Execution Plans tab, this preview includes all the tasks, regardless of the source or target.

Copy Record

This command creates a copy of the selected subject area and also copies the references to table groups.
