<P>隨著XML逐漸受到越來越多的重視，Informix公司也發(fā)布了其XML策略：快速、簡便地構(gòu)造高性能、可縮放、基于XML數(shù)據(jù)驅(qū)動(dòng)的Internet應(yīng)用，支持和加速開放標(biāo)準(zhǔn)。</P>
<P>首先，Informix公司在其數(shù)據(jù)庫產(chǎn)品Informix中加入XML支持。作為Informix Internet Foundation
2000的一部分的Informix Web DataBlade模塊，可以通過一個(gè)簡單的SQL接口產(chǎn)生動(dòng)態(tài)的XML數(shù)據(jù)和文檔。</P>
<P>另外，Informix還開發(fā)了一種稱作XML
Mapper的應(yīng)用，它使得開發(fā)者可以在Informix數(shù)據(jù)庫中存儲和檢索XML數(shù)據(jù)。利用一組SQL表格和一個(gè)XML文檔模板，XML
Mapper能夠自動(dòng)生成文檔對象代碼。例如，假定有兩個(gè)數(shù)據(jù)表（作者和圖書）以及一個(gè)包含作者信息的XML模板，那么，就可以產(chǎn)生一個(gè)內(nèi)置存儲和檢索XML功能的Java類。一般情況下，在該Java代碼中會(huì)有兩個(gè)關(guān)鍵的方法實(shí)現(xiàn)：getXML和setXML。在前面我們所做的假定條件下，getXML方法可以返回一個(gè)包含作者數(shù)據(jù)的字符串，而setXML則可借助XML模板進(jìn)行數(shù)據(jù)庫中數(shù)據(jù)的插入和修改。Informix
XML Mapper 還可以生成一個(gè)servlet，它能夠從數(shù)據(jù)庫中取得數(shù)據(jù)，然后在Web瀏覽器中顯示。<BR><BR>相關(guān)網(wǎng)址：<A
