This paper extends a theory of risk-based test planning that was outlined in a previous paper, introduces techniques to facilitate it, explains their practical application, and highlights opportunities for research to enquire into their feasibility and efficacy.

Query optimization is a computationally intensive process, especially for complex queries. We present here a tool, called PLASTIC, that can be used by query optimizers to amortize the optimization cost. Our scheme groups similar queries into clusters and uses the optimizer-generated plan for the cluster representative to execute all future queries assigned to the cluster. Query similarity is ev...
