When a database is set up initially its structure is designed to match the expected pattern of usage. With time, changes to the database and to its pattern of usage may cause the structure to be less than ideal for the pattern of usage, and the database may need to be reorganized. A set of tools is described which will assist the database administrator in the tasks associated with reorganization. The tools have been implemented in Prolog and incorporated into a database accessed via the database language Query‐by‐Example.
