【摘要】 以城市地震应急指挥技术系统(UEECTS)数据管理为研究背景,将空间地理信息系统技术引入数据管理领域,为UEECTS系统设计并开发了数据管理子软件系统,在实现对UEECTS系统数据空间可视化展示的基础上,实现了对系统数据的查询、添加、删除及修改数据管理操作,为城市UEECTS系统建设提供了良好的数据支持。针对UEECTS系统的数据规划以及数据管理子软件系统的开发与实现做了详细讨论与阐述,以期为全国范围内UEECTS系统数据库的建设以及数据管理子软件系统的开发应用提供通用性模型。更多还原

【Abstract】 Based on the research on data management of urban earthquake emergency command technology system(UEECTS),in the paper geographic information system(GIS) is applied to the field of data management,and database management subsystem(DBMS) is further designed and developed for UEECTS.The spatial distribution of UEECTS’ system data is realized by the DBMS,and moreover management functions of the data query,addition,deletion and modification are achieved.The establishment of DBMS provides strong data support for UEECTS.In this work,the UEECTS’ system database planning and DBMS’ development are discussed and illustrated in detail,a general model is provided for UEECTS’ system database establishment and DBMS’ realization.更多还原
