Extension of xquery in a high performance xml/xquery database

摘要

A system for extension of XQuery in a binary object XML repository includes XQuery interpreter (110) capabilities for implementing the XQuery language in the binary object XML repository. A function dispatcher module (120) implements an XQuery call mechanism, with the function being defined by the name of the function, the number of arguments taken by the function, and the datatypes of the arguments. A plug-in function library manager (130) implements the client side of the binary object XML repository plug-in function application program interface, and a dynamically-linked plug-in function library (140,150) module for implements the server side of the binary object XML repository plug-in function application program interface.
