CA IDMS/DB Analyzer is a parameter-driven batch utility that examines the physical structure of a database, creates an iterative statistical data file based on this examination and then produces a series of user-requested analytical reports.
CA IDMS/DB Analyzer examines a database and collects data on important physical characteristics within areas, within record and set types, and within the index or indexes associated with the database.
This data is stored in the statistical data file. Since the statistical file is iterative, storing several generations of historical data, CA IDMS/DB Analyzer can compare current statistics with historical statistics or two different sets of historical statistics with each other. This capability allows you to detect trends in the database over a period of time or to assess the effects of reorganization.
CA IDMS/DB Analyzer creates reports by using information either taken directly from the database or computed from the contents of the statistical file.
