基于需求驱动的数字化校园数据架构研究与设计

Research and design of digital campus data architecture driven by demand

近年来,在数字化校园建设中,以数据服务为核心,为不同角色提供人性化信息服务,以及为学校发展提供决策支持的需求应运而生。而单一的统一数据库在应用系统和业务规模扩大时其应用查询效率较低,为此设计出一种新的数字化校园数据架构,将数据交换库与共享数据库分离,使数据存放更为有效,从而提高查询效率。从理论上和技术上对新的数据架构进行了可行性分析。新的数据架构能够较好地满足数字化校园建设中的新需求。

In recent years, during the construction of the digital campus, it takes data services as the core, provides personalized information service for different roles and demands for decision supports. However, a single unified database has lower query efficiency when the scale of the system becomes large. In this paper, a new data architecture for the digital campus is presented. It separates the data-exchange database and the data sharing database and makes the data storage more effective. Moreover, the query efficiency is improved. From the feasible analysis on theory and technology, the new data architecture can satisfy the demand during the construction of the digital campus.
