CAREER: Research and Development of Database Technologies for Modern Applications

该项目的目标是开发数据库技术，以满足数据密集型应用程序的需求，这些应用程序处理分布式、空间和多媒体数据源。研究工作主要集中在：(1)开发新的空间查询处理算法，在查询执行期间可以动态和灵活地重新排序和调整，以解决响应时间的波动和来自各种基于Web的空间数据源的意外延迟；(2)开发索引技术和技术，以促进将非传统的空间和高维索引结构嵌入数据库系统；以及(3)开发可扩展的磁盘调度算法，以实现多媒体应用的多种服务质量要求。这些研究任务产生的技术将有助于在数据库系统中有效地支持现代应用程序，并将使数据库系统能够匹配这些应用程序动态变化的需求。教育工作的重点是：(1)本科生和研究生都参与实践研究活动和实验；(2)开发若干课程要素，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)开发一个多媒体数据库和信息系统实验室，以促进研究成果与教育的整合；以及(4)促进学生的产业互动。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--将被公开传播，并与数据库系统领域的同事、学生和行业合作者分享。

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.
