Query Processing in Distributed Database System
IEEE Transactions on Software Engineering, 1979Query processing in a distributed system requires the transmission f data between computers in a network. The arrangement of data transmissions and local data processing is known as a distribution strategy for a query. Two cost measures, response time and total time are used to judge the quality of a distribution strategy.

An adaptable distributed query processing architecture
Data and Knowledge Engineering, 2005Traditionally, distributed query optimization techniques generate static query plans at compile time. However, the optimality of these plans depends on many parameters (such as the selectivities of operations, the transmission speeds and workloads of servers) that are not only difficult to estimate but are also often unpredictable and fluctuant at ...

The state of the art in distributed query processing
ACM Computing Surveys, 2000Distributed data processing is becoming a reality. Businesses want to do it for many reasons, and they often must do it in order to stay competitive. While much of the infrastructure for distributed data processing is already there (e.g., modern network technology), a number of issues make distributed data processing still a complex undertaking: (1 ...

ACM Computing Surveys, 1984
In this paper, various techniques for optimizing queries in distributed databases are presented. Although no attempt is made to cover all proposed algorithms on this topic, quite a few ideas extracted from existing algorithms are outlined. It is hoped that large-scale experiments will be conducted to verify the usefulness of these ideas and that they ...

Distributed Query Processing on the Grid
The International Journal of High Performance Computing Applications, 2002Distributed query processing (DQP) has been widely used in data intensive applications where data of relevance to users are stored at multiple locations. This paper argues: (i) that DQP can be important in the Grid, as a means of providing high-level, declarative languages for integrating data access and analysis; and (ii) that the Grid provides ...

Experiences with distributed query processing
[1990] Proceedings. Sixth International Conference on Data Engineering, 2002Different implementations of an experimental distributed query processing system which is constructed on top of existing database management systems (DBMSs) are presented. A performance evaluation is carried out. It is shown that the response times of query execution are affected significantly by the degree of site autonomy, interferences among ...

Distributed query processing in Cronus
[1989] Proceedings. The 9th International Conference on Distributed Computing Systems, 2003Four distributed query processing strategies under consideration for incorporation into the Cronus object-oriented distributed computing environment are described. Under Cronus, object storage can be embedded inside applications, and facilities are provided to distribute and replicate automatically the data maintained by the application.

Query processing in Distributed PIOS
Proceedings of 7th International Conference and Workshop on Database and Expert Systems Applications: DEXA 96, 2002An approach to query processing in object oriented distributed database systems is proposed. Distributed PIOS is a server that supports an object-oriented data model, physical data independence (i.e. different strategies for storing class hierarchies, grouping, horizontal and vertical partitioning of objects), and fragmentation transparency (i.e ...

Query processing in distributed ORION
2005In this paper we describe query processing strategies we have developed and implemented in the distributed version of the ORION object-oriented database system. The ORION query model is based on the ORION object-oriented data model. Further, we have adopted the response time as the primary objective function for query optimization. The query-processing
