XU Rong-sheng · Jisuanji gongcheng · 2011
For the requirements of multi-source heterogeneous data query in information security development and research work,a multi-source heterogeneous data query middleware system is designed and implemented based on the analysis of network security data structure.This system applies and extends Language Integrated Query(LINQ) technology,achieves transparent query through query parsing,name mapping,specific expression tree generation and result set processing steps,and supports a variety of data sources,including popular databases,XML and JSON formats,etc.It is also easy for expansion and redevelopment.
