Universal algorithm of processing of requests with use of parallel technology

Abstract

Processing and storage of a large amount of information is one of the difficult and interesting tasks at the moment. The performance of the system as a whole depends on how well the performance and reliability of the database are implemented. One of the most difficult aspects of this issue is the handling of a database query and its efficient execution. In this paper we consider modern methods and models of query processing in databases. We offer an algorithm to service the request of users, which involves the use of parallel technologies in the exchange of information with the nodes of a distributed database and a dictionary, and also allows to increase the query execution time, which in turn will increase the speed of the system as a whole. We bring the current at the moment the technology of storing large amounts of data: distributed and parallel databases, MapReduce.
