Method and system for generating indexes in an XML database management system

摘要

The invention concerns a method for generating at least one index (10) over XML documents (30) in an XML database (40); the method comprising the steps of: a. executing at least one indexing function (20) defined in the XQuery language; each indexing function (20) accepting an XML document (30) as input and returning at least one computed result; and b. storing each of the at least one computed results from the at least one indexing function (20) as a key (11) of the corresponding index (10) and a reference to the input XML document (30) as a value (12) of the index (10).
