A data management system and method. The system is adapted to analyze a plurality of data queries and provide a metric with respect thereto. The system then orders the queries based on the metric to improve a performance parameter of the system or estimate an execution time with respect to the query. In a more specific implementation, the system includes code for analyzing a signature of each of the queries, comparing the signature to a calibrated signature and providing a signature score in response thereto. The system further includes code for estimating an execution time of at least one of the queries. The signature may be a cluster of statements in an appropriate language such as SQL (standard query language). As an alternative, the signature may be a set of features extracted from a plurality of statements.
