Area Change Modeling Utility

The Area Change Modeling Utility can be used to evaluate potential benefits or effects of changes to an existing DEDB before implementation.

This utility provides a comprehensive DEDB modeling and prototyping facility. Information derived from using this utility can be used to help you better meet your application performance or space utilization requirements.

The Area Change Modeling Utility helps you to:

determine database attribute and parameter value selection
identify and select the physical database attributes that meet the desired performance and space utilization requirements (optimal values for the ROOT and UOW parameters)
eliminate database maintenance required when a database does not meet performance and/or space utilization expectations after reorganization
simplify the evaluation and selection of suitable randomizing routines
evaluate the potential benefits or effect of database reorganization
easily perform multiple iterations of the database modeling process, letting you select physical database attributes that meet the desired performance and space utilization requirements
model the potential space utilization and performance effects of converting a full-function IMS database to the DEDB format

With the Area Change Modeling Utility, you can change and model any or all of the following database specifications:

randomizing module (change in type of randomizer used)
UOW parameter values
ROOT parameter values
number of database areas
CI sizes
changes to hierarchical database structure

The Area Change Modeling Utility produces a series of reports that provide detailed information about the performance space utilization effects of the modeled database changes.
