Calibrating the Query Optimizer Cost Model of IRO-DB, an Object-Oriented Federated Database System
Summary: Calibrating the query optimizer cost model of IRO-DB, an object-oriented federated DB. It tunes per-site cost coefficients using a calibration object-oriented database of linked objects and a local tuning app, validating accuracy on OO7 path traversals over ObjectStore.
