Query Processing and Optimization in Modern Database Systems
Relational database management systems, which were designed decades ago, are still the dominant data processing platform. Large DRAM capacities and servers with many cores have fundamentally changed the hardware landscape. Traditional database systems were designed with very different hardware in mind and cannot exploit modern hardware effectively. This thesis focuses on the challenges posed by...
متن کاملTemporal Query Processing and Optimization in Multiprocessor Database Machines
In this paper, we discuss issues involving temporal data fragmentation, temporal query processing, and query optimization in multiprocessor database machines. We propose parallel processing strategies, which are based on partitioning of temporal relations on timestamp values, for multi-way joins (e.g., complex temporal pattern queries) and optimization alternatives. We analyze the proposed sche...
متن کاملQuery Processing and Optimization in Distributed Database Systems
Query processing is an important concern in the field of distributed databases. The main problem is: if a query can be decomposed into subqueries that require operations at geographically separated databases, determine the sequence and the sites for performing this set of operations such that the operating cost (communication cost and processing cost) for processing this query is minimized. The...
متن کاملCollaborative Caching for Distributed Mobile Database Query Processing
As mobile applications are becoming increasingly widespread, the need for developing schemes to improve the performance and reliability for mobile database management increase. In addition, caching data in a wireless mobile computer adds an advantage to mobile applications by reducing the bandwidth requirement due to battery power limitation when disconnection occurred. In this paper, we invest...
متن کاملService Mechanism Quality for Enhanced Mobile Multimedia Database Query Processing
Among the challenges of multimedia and mobile computing, providing a mechanism for data retrieval in multimedia databases under wireless mobile environments is one of the most difficult issues (Shih, 2001). Up to now, the fundamental technologies that are specialized for wireless mobile, multimedia environments are not mature in object-oriented, object-relational, as well as relational database...
