XQuery API for Java (XQJ) refers to the common Java API for the W3C XQuery 1.0 specification. The XQJ API enables Java programmers to execute XQuery against an XML data source (e.g. an XML database) while reducing or eliminating vendor lock in. The XQJ API provides Java developers with an interface to the XQuery Data Model.〔(XQuery 1.0 and XPath 2.0 Data Model (XDM) )〕 Its design is similar to the JDBC API which has a client/server feel and as such lends itself well to Server based XML Databases and less well to client-side XQuery processors, although the "connection" part is a very minor part of the entire API. Users of the XQJ API can bind Java values to XQuery expressions, preventing code injection attacks.〔(Binding Java Variables )〕 Also, multiple XQuery expressions can be executed as part of an atomic transaction. ==History and implementation== The XQuery API for Java was developed at the Java Community Process as JSR 225. It had some big technology backers such as Oracle,〔Querying XML: XQuery, XPath, and SQL/XML in context - Jim Melton and Stephen Buxton.

The XQJ classes are contained in the Java package (javax.xml.xquery ) There is no (visible) activity to create a version of XQJ that provides support for XQuery 3.0 or 3.1, for example by providing Java bindings for additions to the data model such as functions, arrays, or maps. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「XQuery API for Java」の詳細全文を読む スポンサード リンク
