An analysis, association, storage and access method and device for data in a city information model

The invention discloses an analysis, association, storage and access method and device for data in a city information model, and the method comprises the steps of achieving the data analysis among objects in the city information model through employing a relation type definition, an association relation instance definition, an object type definition, a global dimension type definition, an attribute type definition, an attribute set definition, an operation set and an attribute set definition data type; the invention can support complex object type expression and internal data attribute definition, can perform complex multi-dimensional association, can integrate various types of external data sources seamlessly and transparently, and support the urban scale-level mass data storage capacity. 一种城市信息模型中数据的分析、关联、存储和访问方法和装置，使用关系类型定义、关联关系实例定义、对象类型定义、全局维度类型定义、属性类型定义、属性集定义、操作集和属性集定义数据的类型，实现城市信息模型中对象间的数据分析，支持复杂的对象类型表达和内部数据属性定义，能够进行复杂的多重维度关联，能够无缝透明的集成各种类型的外部数据源，并支持城市尺度级别的海量数据存储能力。
