Distributed DBMS Query Optimization in Distributed Systems

Specifically, we describe how the storage manager, the query execution engine, and the query optimizer of a database system can be extended to deal with compressed data.

We next analyze the query optimization problem and reduce it to a join ordering problem.

We introduced a new class of portable query plans for executingJava extensions together with relational database operations, and we extendedthe Cornell Predator object-relational system with a lightweight queryexecution engine capable of evaluating these portable query execution plans.

Query Optimization Concepts in Distributed Database

I would like to thank my supervisor Dr Dan Olteanu for his incredible level of enthusiasm and encouragement throughout the project. I am also very grateful for the continuous level of feedback and organisation as well as the amount of time he has devoted to answering my queries. I feel that I now approach complex and unknown problems with enthusiasm instead of apprehension as I used to. I couldn’t The query optimizer is widely considered to be the most important component of a database management system. It is responsible for taking a user query and searching through the entire space of equivalent execution plans for a given user query and returning the execution plan with the lowest cost. This plan can then be passed to the executer, which can carry out the query. Plans can vary significantly in cost therefore it is important for the optimizer to avoid very bad plans. In this thesis we consider queries in positive relational algrebra form involving the conjunction of projections, selections and joins. The query optimization problem faced by everyday query optimizers gets more and

...n time. Given a query to process, one of the strategies present in an optimizer is chosen to optimize lhal query. The Epoq approach to query optimization is related to the knowledge-baaed approach of =-=[22]-=-. Epoq regions form a knowledge base of information about query processing ntrategies. The control presented here contains knowledge about ways to combine these strategies to process a query. The Epoq...

Query optimization in fragmented distributed database systems

data modeling, Object-oriented databases, Query optimization, Semantic Integrity.

We devised a new framework for database compression and newquery processing and query optimization strategies to integrate compressioninto a modern query processor.

Our models and solution methods can be the starting point for eventual resolution of these complex problems in large scale distributed database systems.

While this algorithm produces good optimization results (i.e., good plans), its high complexity can be prohibitive if complex queries need to be processed, new query execution techniques need to be integrated, or in certain programming environments (e.g., distributed database systems).
