ABSTRACT:
A database view generation system for viewing a result set of data extracted from a database by a query. The database view generation system includes selecting a viewpoint from among at least one field set record source of a database sub-schema and generating a view of the result set in at least one level from a perspective of the viewpoint. Generating a view from a viewpoint includes analyzing the sub-schema for connectedness, identifying the sub-schema type, assigning a level indicator value that is indicative of the hierarchical position of record sources in the sub-schema relative to the viewpoint, and displaying a view of the result set based on the level indicator value assigned to each record source containing data in the result set.
