The Research of Multi-source Heterogeneous Data Integration Based on LINQ
Yunxiao Wang, Xuecheng Zhang · 2012
In allusion to the situation that software systems often need to access the heterogeneous multi-source data, this paper presents a kind of data integration technology based on LINQ. The software systems applying this technology are designed into three-layer structure, with the business logic layer decomposing the query logics and integrating the query results, and with the data access layer accessing all kinds of data sources and getting the necessary data of unified format with LINQ provider assemblies to facilitate data integration. The application of LINQ in data integration can simplify the software development process, improve the software development efficiency, as well as improve the effect of data integration. This technology achieves a more efficient integration of multi-source heterogeneous data and is conducive to expanding system functionality.
