给出了空间数据和属性数据的数据结构,在此基础上采用面向对象数据库(OODB)技术中的对象组织和管理思想,采用数据模板和方法模板技术建立面向对象的数据访问模型,并在此基础上建立了一种面向对象的空间查询和空间分析模型。首次采用方法元库的设计思想来解决面向对象数据库中各对象方法的定义问题,方法元库中具有丰富的方法元,能够满足各对象复杂方法的构造需要。
Give the data structure of spatial data and categorical data, on which introduced object organizing and managing theory in OODB and template technology including data template and method template, mode OO data access model and spatial query and spatial analysis model. In this paper, adopt the meta-method library to resolve the method defining of object in OODBs for the first time, in which there is abundant meta-method that can meet with demand of construction of complicated object method.
