摘　　要：提出了数据库设计二阶分析模式 ,将二者分别应用于空间数据建模和数据库结构设计中 ,并以国土资源与房地产管理综合管理系统数据库设计中房地关联部分为例对二阶分析模式的应用进行了说明 ,对模式的可行性进行了论证。Building the spatial data model and designing the structure of the database are the two relatively important parts in GIS database design.Object_oriented integrity data model and object_oriented semantic data model are two new models usually used in database design.They are focused on two different aspects of GIS database design but share the same principle in abstracting the object of the basic spatial entity. Based on this character of these two models,an analysis mode for GIS database design called two_order analysis mode is introduced in this paper.The two_order analysis mode can be used for the whole process of the GIS database design, including building data model and designing the structure of database. A practical design in the land use and real estate management system is analyzed as an example to testify the feasibility of the mode.
