A query optimization model for object relational databases.
Zhang, Xu.

A query optimization model for object relational databases. - 159 p.

Source: Dissertation Abstracts International, Volume: 67-03, Section: B, page: 1538.

Thesis (Ph.D.)--University of California, Irvine, 2006.

This dissertation addresses the query optimization problem for object relational databases. A novel query optimization model, including an object relational algebra, equivalence rules, heuristics and cost estimation, is introduced. We believe this is the first query optimization model based on an object relational algebra. We also propose an optimizer architecture based on this model for SemanticObjects, an object relational application development platform. Two applications, namely a biological image database and a chemical structure database, have been developed to test our query optimization model.

520 $a An object relational database is powerful in modeling real world applications by adding the concept of object to a relational database. It has a broad application in areas that involve complex structures. However, query optimization is extremely important and critical, since users cannot wait for hours to get their results.
