Abstract
The software tool of this invention estimates the costs of an application program accessing a database. These costs may be execution costs of the application or of a transaction, SQL statement, and/or a utility. Execution costs include CPU time, I/O time and minimum elapsed time. For estimating the execution costs, the tool receives simplified and partial definitions of tables, utilities, SQL statements, transactions, and applications. The estimator tool requires only a minimal amount of information to calculate the various execution costs.
