In order to resolve the problems of the existing solutions of heterogeneous data integration,including no uniform standard for the treatment of heterogeneous data,too much hard-coded and poor extendibility,propose a solution based on SDO for heterogeneous data integration.It designs and achieves a unified data access interface;Data access service encapsulates multiple data resources and returns results using the same format,which unifies the methods of data access and data manipulation;A query decomposition method based on configuration files of data sources is given in query decomposition respect.By the configuration files,the integration system can obtain connections with the corresponding data sources.And as long as the configuration file is modified,the system can implement the flexible modification of data sources.Finally,the integrated solution is applied to the PLM system based on WEB project,and its feasibility is verified.The experimental result illustrates that this solution can reduce the ease of development,and has good extendibility and high efficiency. It can very well meet the needs of heterogeneous data integration.
