摘要
从整体上描述了GIS空间数据模型的发展,简要介绍了Geodatabase数据模型的特点及优势,列举了创建Geodatabase数据库通用的3种方法,重点探讨了用CASE工具建立基于Geodata-base城市公共安全数据库的具体过程,为城市公共安全数据库的建立提供了1种有效可行的方法和途径。研究表明,用这种方法建立城市公共安全数据库可以将面向对象方法很好地应用于空间数据库的设计中,大大缩短了建库时间,提高了建库效率,使得在此基础上建立的城市公共安全信息系统能更有效地服务于社会。
The article describes the development of GIS spatial data model, introduces the characteristics and advantages of Geodatabase data model, enumerates three common methods for building Geodatabase, discusses how to build city's public safety database with case tools , then provides one kind of method and approach. The study proved that object-oriented method can be properly applied to designing spatial database using this method, greatly reduced the time and improved the efficiency of building a database, and make city's public safety information system more better serve to society.
