中文摘要: 随着传感网、物联网的快速发展与广泛应用,感知数据的规模呈现了急速增长的趋势,我们已经走进了感知大数据的时代。感知大数据兼具大数据和感知数据的典型特征,传统的感知数据管理技术和大数据管理技术均无法有效地管理感知大数据。查询处理是感知大数据管理研究的核心内容,而查询优化是影响查询处理性能的关键因素。本项目考虑感知大数据的实时流、时空相关和不确定等特点,紧紧地围绕面向感知大数据的不确定查询处理与优化问题,将重点针对感知大数据获取、感知大数据存储、感知大数据索引和不确定查询处理与优化算法等关键技术展开深入的研究工作,并设计开发一个面向感知大数据的不确定查询处理与优化的原型系统来验证相关研究成果的正确性和有效性。该项目的研究工作对于推动感知大数据管理技术与应用,以及发展我国新型数据库产业,具有非常重要的理论研究意义和实际应用价值。

英文摘要: With the rapid development and wide usage of the sensor network and Internet of Things (IOT), the scale of the sensed data increases sharply, and it is hence the epoch of Big Sensed Data (BSD) nowadays. BSD mixes the typical features of both big data and sensed data. However, the traditional data management technology on neither sensed data nor big data can effectively support BSD management. Query processing is the core of BSD management, while query optimization is the key factor impacting on the query processing performance. In this proposal, considering the characteristics of the realtime streaming, spatio-temporal correlations and uncertainty of BSD, we concentrate on the key techniques of BSD acquisition, storage, indexing, and uncertain query processing and optimization algorithms based on the problems on uncertain query processing and optimization for BSD. The prototype system on uncertain query processing and optimization for BSD will be designed and implemented in order to verify the correctness and effectiveness of the related research results. The study on this project has very important theoretical and practical impact on pushing forward the BSD management technologies and applications, as well as the national new type database industry.
