Description: 应用分类列举的方法，研究了基于B／S结构的空间关系数据库的集成两类模式— — 以服务器为主空间数据库集成模式和以客户端为主空间数据库集成模式。列举了这两种模式的各种方案：CGI模式、Sever API模式、Java Servlet和Applet模式、插件(plug-in)模式、Active X控件模式。以Mapobjects IMS的CGI为例，给出空间关系数据库集成方案的应用模式，表明了这种方案的可实践性。最后，指出了基于B／S结构空间数据库集成方案的研究方向。-Application of classification method cited study based on B/S structure of the integration of two types of spatial relational database model-- to the server-based spatial database integration model and to client-based spatial database integration model. Both models listed programs: CGI mode, Sever API mode, Java Servlet and Applet mode, plug (plug-in) mode, Active X control mode. To Mapobjects IMS of CGI, for example, relational database integration solutions are given space application mode, that this scheme can be practical. Finally, pointed out that based on B/S structure with database integration research program. Platform: |

Description: 在认识的基础上进行逐步抽象，最后得到数字化的空间数据，这正是OpenGIS九层抽象模型前五层所描述的内容。最后是空间数据库模型，进一步强调了该抽象过程。
本章的内容有助于加深对空间数据和空间信息的理解。
-On the basis of the gradual understanding of the abstract, the resulting digital spatial data, which is nine OpenGIS abstract model described in the contents of the previous five. Finally, spatial database model, further emphasized the abstract process. This chapter will help to enhance spatial data and spatial information for understanding. Platform: |
