摘 要:全关系型数据存储模式将GIS数据的空间数据和属性数据统一存储于关系数据库中,分析Java应用程序通过JDBC和SQL语言访问关系数据库中存储的GIS数据的不足,提出基于。Hibernate的解决方案,并给出地理信息共享系统的开发实例。The total - relationship organization mode integrates the GIS spatial data and attribute data into the RDBMS, which becomes the main storage pattern. To access GIS data in RDBMS in the Java environment, the method of using JDBC API and SOL program language directly is adopted usually. However, it has some shortcoming in the development and execution efficiency. Referring to present situation and future development direction of GIS and Java program,accesslng GIS Database with Hibernate in the Java environment is suggested in this paper. It establishes a mapping between the objects and relational database,and accesses the GIS database by operating those objects and Hibernate API,which acts as a middleware between the Java application and GIS database. It gready increases the development efficiency and system execution speed. These two methods are comparatively discussed by an instance in the devdopment of Geographic Information Sharing System,and two sets of data present the gap.
