The goal of this project is to develop database technologies that address the demands of data-intensive applications, which handle distributed, spatial and multimedia data sources. The research effort focuses on: (1) the development of new spatial query processing algorithms that can be dynamically and flexibly reordered and adapted during query execution to address the fluctuation in response time and the unexpected delays from the various input web-based spatial data sources; (2) the development of indexing techniques and technologies to facilitate the embedding of non-traditional spatial and high-dimensional indexing structures into database systems; and (3) the development of disk scheduling algorithms that scale up towards achieving multiple quality of service requirements for multimedia applications. The techniques generated by these research tasks will facilitate the efficient support of modern applications in database systems and will allow database systems to match the dynamically changing demands of these applications. The education effort focuses on: (1) the involvement of both undergraduate and graduate students in hands-on research activities and experimentation; (2) the development of several curriculum elements including two courses and three educational tools, and the introduction of these tools into the existing and newly developed courses; (3) the development of a multimedia database and information systems laboratory to facilitate the integration of research results and education; and (4) facilitating industrial interaction for students. The outcomes of this project -- including newly developed database technologies, research tools, and curriculum elements -- will be publicly disseminated and shared with colleagues, students, and industrial collaborators in the database systems area.

该项目的目标是开发数据库技术，以满足处理分布式、空间和多媒体数据源的数据密集型应用程序的需求。研究工作集中在：（1）开发新的空间查询处理算法，该算法可以在查询执行过程中动态灵活地重新排序和调整，以解决响应时间的波动和各种基于Web的空间数据源的意外延迟;（2）开发索引技术和技术，以促进嵌入非传统空间和高分辨率数据，数据库系统的多维索引结构;以及（3）磁盘调度算法的开发，该算法可按比例增加以实现多媒体应用的多种服务质量要求。这些研究任务所产生的技术将促进现代应用程序在数据库系统中的有效支持，并允许数据库系统，以满足这些应用程序的动态变化的需求。教育工作的重点是：（1）本科生和研究生都参与实际研究活动和实验;（2）开发若干课程内容，包括两门课程和三种教育工具，并将这些工具引入现有和新开发的课程;（3）发展多媒体资料库及资讯系统实验室，以促进研究成果与教育的结合;及（4）促进学生与工业界的互动。该项目的成果-包括新开发的数据库技术，研究工具和课程要素-将公开传播，并与同事，学生和数据库系统领域的工业合作者共享。
