ITR/IM: Handling Uncertainty in Spatial Databases

这个研究项目的目标是开发新的技术来处理面向对象的动态数据库中的不确定性。该方法包括开发新的数据模型和相关的代数；开发针对不精确查询的查询优化技术；以及开发索引方法以支持动态数据库中的概率不确定性。这项研究工作开发了新的理论、工具和技术来支持面向对象的动态数据库中的各种类型的概率不确定性。实验研究与空间数据库相联系，在地理信息系统领域中的应用。通过在数据库管理系统中增加对不确定性的支持，该研究项目将大大提高在测量和使用不确定性的商业、社会、科学和工程工作的广泛类别中数据库管理的能力和灵活性。Http://www.vislab.ucr.edu/intro.html

The goal of this research project is to develop new techniques to handle uncertainty in object-oriented dynamic databases. The approach consists of developing a new data model and associated algebra; developing query optimization techniques for inexact queries; and development of indexing methods to support probabilistic uncertainty in dynamic databases. This research effort develops new theory, tools and technology to support various types of probabilistic uncertainty in object-oriented dynamic databases. The experimental research is linked to spatial databases with applications in the field of Geographic Information Systems. By adding support for uncertainty in database management systems, this research project will substantially increase the power and flexibility of database management in a broad class of business, social, scientific and engineering endeavors where uncertainty is measured and used. http://www.vislab.ucr.edu/intro.html
