Research And Application Of Object Persistence Based On .NET

At present,in the enterprise application development environlnellI．111e development of object persistence approach has become mainstream Objects Call only exist in memory,and memory can not be the permanent preservation of data To save a permanent state ol'the object,the need for object persistence,object to the pemlanent storage ofdata storage devicesThe text offers a method of mapping between a NET object and Lucene．net Documents through the research of the full text of the Search engine tool Lucene．net working principle,and system and structnre ofthe index file stnlcture And it achi e,,es a persistent component n ith a Ltlcene．net storage deviccBy the demand analysis of persistence player,this paper designs and achieves aobject persistence framework EasyTask with the using of a flc system as a storagedevice The framcwork consists of two core components:Lucene net storage devicesas che target of persistent components and the XML fle storage devices as t11e objectof persistent COlnponents This papel'designs and achieves an electronic recordstnanagement system with Lucene net storage devices and a lasting layer by EasyTaskframework The development of this management systems and its stable oDcrationprove that to achieve object persistence by the Llse of search engi ne technologyin NET platlbnn is feasible．And,in the framework of EasyTask．Lucene．net isresponsible for tim objects storage and the fidl—text search function．T11e full textretrieval of infomlation and target infoiTnation aI。preset,ved together to avoidredundancy...
