When Processing is Required

The data dictionary’s input processes track modifications that, when they occur, require the dictionary (or selected portions of it) to be processed. By tracking situations that require processing, APPX can eliminate errors by removing the possibility that other components within APPX will access obsolete data specifications.

The following paragraphs describe conditions for which processing is required:

· Domains require processing after they are added to the dictionary and whenever their specifications have been modified. Processing of domains is automatic in APPX. If a domain requires processing, all fields that reference the domain also require it. If a domain is deleted from the dictionary, any remaining fields that reference the domain must be modified and processed.

· Files require processing after they are added to the dictionary and whenever their specifications are modified. Processing of files is automatic in APPX. In addition, a record/file must be processed whenever fields are added or deleted, or a field specification is modified. If a record/file is deleted from the dictionary, its associated fields are automatically deleted. The dictionary does not have to be processed.

· Work fields must be processed whenever a work field is added or deleted, and whenever a specification for any work field is modified. Processing of work fields is automatic in APPX. If any work field requires processing, all work fields are processed.
