Temporal 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 کاملAdvance Database Aggregation Query Processing
The aggregation query is an important but costly operation in database management systems. In the worst case, to compute an aggregate, all tuples in a database needs to be examined. However, in many applications (on-line analysis, etc.), we need to compute the aggregates very fast. In the Ph.D. research, we focus on devising specialized indices for the box-aggregation query and its relatives. O...
متن کاملUsing Graphic Cards for Accelerating Raster Database Query Processing
Advances in satellite and drone imagery and sensors allow researchers to capture vivid, comprehensive and detailed snapshots of the surrounding environment, be it from a satellite looking down on earth, from a unmanned underwater vehicle or from a medical fMRI scanner. All these devices generate large amounts of data that ends up as a N-dimensional table of numbers stored on a computer. Capturi...
متن کاملIntegrating Encrypted Cloud Database Services using Query Processing
In today’s environment the various vital information should need to be stored in more secured manner. In the cloud computing, original plain data must be accessible only by trusted parties that do not include internet and cloud providers or intermediaries. Storing this confidential information in cloud must provide guarantee of availability of data and security. there are too many solutions are...
