With the network's development and the construction of enterprise information,the problem of information islands is increasingly prominent within the enterprise.In order to better share information,a multi-source data integration framework of virtual view based on SDO is proposed by analyzing the SDO architecture.The framework uses XSD to describe the multiple data source information,uses LAV mapping global view,and then uses DAS to realize the underlying access of the different data sources.Describe in detail the composition of the frame system and work flow,and give a concrete realization of the process.Examples show that the schema is effective in masking the underlying differences in multi-source data,and achieving the integration of multiple data sources to solve the information island problem.
