房地产空间数据与非空间数据的关联──门牌号的研究

Study on doorplate which connecting real estate spatial data and non spatial data

在房地产及其相关的领域里涉及到大量的空间数据和非空间数据，如何有效地将它们连接起来，实现查询和定位是该领域的一个重要且亟需解决的问题。论述了门牌号的概念、特点、类型及特性，包括门牌号的“一对一”和“一对多”的特点和时间性。论证了其定位和查询的作用，并探讨了实现的途径。最后总结了门牌号在不同类型的房地产 MIS(Management Information System)和 DSS(Decision Support System)中的作用，从而为空间数据库和非空间数据库的连接提供了有效的手段。

In the fields of real estate there are plenty of spatial data and non spatial data. The way which connects spatial and non spatial data will be an important subject. Doorplate and its feature including“ one to one” and“ one to many” in GIS(general information system) are introduced in this paper, and its position in both GIS and GIS－ Based Real Estate MIS(management information system)＆ DSS(decision support system) is discussed, and at the end of this paper its function in several types of Property MIS＆ DSS is also discussed. Doorplate would be an effective way to connect spatial and non spatial data.
