CAREER: Peer-Based Data Integration and Sharing of Heterogeneous Sources

本研究项目的目标是研究如何在分布式环境中支持高效的数据集成和共享的研究挑战。该方法包括(1)如何描述各种源内容并允许用户轻松地制定查询；(2)如何有效地管理源元数据；(3)如何处理数据异构性(例如，链接来自不同源的重复记录)；(4)如何优化涉及多个源的分布式查询。这项研究提供了很好的机会，教育学生了解现有的数据库管理技术，并启动他们的研究。有关该项目的更多信息可在网站上找到(http://www-db.ics.uci.edu/pages/raccoon/).研究成果将在电子商务信息管理、科学数据管理、数字政府、国土安全等领域产生广泛影响。结果将以出版物、公开提供的数据集、软件和演示的形式传播。该项目的工作人员将在会议和座谈会上发表演讲。

The goal of this research project is to study research challenges to support efficient, effective data integration and sharing in distributed environments. The approach consists of (1) how to describe various source contents and allow users to formulate queries easily; (2) how to manage source metadata effectively; (3) how to deal with data heterogeneity (e.g., link duplicate records from different sources); and (4) how to optimize distributed queries that involve multiple sources. The research provides great opportunities to educate students about existing database-management techniques as well as initiating them into research. Further information about the project can be found on the web site (http://www-db.ics.uci.edu/pages/raccoon/). The research results will have broad impacts in information management in e-commerce, scientific data management, digital government, and homeland security. The results will be disseminated in the form of publications, publicly available data sets, software, and demos. The personnel of the project will give presentations in conferences and colloquia.
