CAREER: New Technologies for Approximate Query Processing

点击翻译按钮获取中文摘要

One of the two goals of the project is to advance the state-of-the art in approximate query processing (AQP), a critical component of analytical processing -- a 3.5 billion dollar segment of the software industry. The need for approximate query processing arises from the growing discrepancy between the volume of information that has to be processed and the computational resources or communication capabilities available. Using two computational models, data-streaming and distributed computation, the project addresses fundamental problems in AQP such as development of new approximation techniques for data-stream computation, extensions of data-stream algorithms to distributed algorithms that can efficiently query sensor and peer-to-peer networks, and theoretical aspects of AQP that allow the design of AQP techniques to be accelerated and better understood. Part of the project's research goal is the design and implementation of a approximate query processing engine that uses the developed AQP techniques and the rigorous benchmarking of the software produced. The second goal of the project is educational and consists in, on one hand, motivating students to study and pursue carers in databases through bonus points for extra activities and integration of the database curricula and other CS disciplines, and, on the other hand, integration of approximate query processing into both undergraduate and graduate curricula. The project will have broad impact by developing techniques for efficient processing of large volumes of data -- crucial for scientific data processing and home-land security -- and by increasing the quality of database education with a direct impact on nation's technological leadership.http://www.cise.ufl.edu/~adobra/AQP
