Research On Data Integration Techniques In The Context Of The Tools Integration

In the context of data integration, in order to realize the interaction and data sharing among system design tools, all data of involved tools is required to be collected together unifiedly for storage and access management, and data format transformation and unified data accessing is necessary to increase the efficiency of design and development.In this paper, a general data transformation component, RCTRANS, is designed based on DFTL and Boost Spirit framework. The component uses XML Schema to describe the logical structure of source data, and then defines the parsing pattern of source data and maps source data model to target XML model by adding annotations. Furthermore, it can be used to transform various kinds of data into the XML format and implemented the requirements. This component provides a unified XML view to access data with heterogeneous formats, which meets the requirement of data sharing. Moreover, a unified data access component, RCSDO, is designed based on the SDO technology which unifies data programming among various types of different data sources and eliminates the differences among different data sources.Experimental results show that it is able to solve the problem of data format transformation and unified data accessing, and achieve the purpose of data integration.
