The invention relates to a multi-source heterogeneous data integration processing method for urban rail transit engineering. The method comprises the steps that data sources are created, and data are classified and stored in source end databases; creating a metadatabase according to each source end database; extracting data of the heterogeneous data source to a transitional database; performing data conversion on the transitional database under the constraint of the rule and the metadatabase; performing data integration and fusion on the converted data to realize unification of a data model and a data format; based on the metadatabase, a metadata manager in the metadatabase defines a target data model structure to obtain a defined data association rule and a target mapping relation; according to a defined data association rule and a target mapping relation, loading the integrated and fused data from the data transition area to a data warehouse physical storage area; and rendering the data of the physical storage area of the data warehouse and publishing the data to a corresponding WebGIS server, and performing multi-source heterogeneous data integrated display of system configuration and service in a specified system.

    本发明涉及一种城市轨道交通工程的多源异构数据集成处理方法,创建数据源并将数据进行分类并存储至各源端数据库;根据各源端数据库创建元数据库;将异构数据源的数据抽取到过渡性数据库;在规则和元数据库的约束下对过渡性数据库进行数据转换;对转换后的数据进行数据集成和融合,实现数据模型和数据格式的统一;基于元数据库,其内部的元数据管理器定义目标数据模型结构,得到定义数据关联规则和目标映射关系;根据定义数据关联规则和目标映射关系,将已经集成和融合成功的数据从数据过渡区加载到数据仓库物理存储区域;将数据仓库物理存储区域的数据进行渲染并发布到相应的WebGIS服务器上,在指定系统中进行系统配置和服务的多源异构数据集成显示。
