Analyzing Plan Diagrams of Database Query Optimizers
A “plan diagram” is a pictorial enumeration of the execution plan choices of a database query optimizer over the relational selectivity space. In this paper, we present and an...

Identifying robust plans through plan diagram reduction
Estimates of predicate selectivities by database query optimizers often differ significantly from those actually encountered during query execution, leading to poor plan choices a...

Design and Analysis of Parametric Query Optimization Algorithms
Query optimizers normally compile queries into one optimal plan by assuming complete knowledge of all cost parameters such asselectivity and resourceavailability. The execution of...
