A modular user-oriented decision support for physical database design

摘要

A decision support package for the design of indexes in a relational database environment is presented. It originates from the theoretical results collected inside the DATAID methodology. Its main features are a high level language user interface, an incremental description of the design environment, a forecasting of the execution I/O costs if the proposed solution is adopted and also a guidance for the access paths to be selected in the various operations.
