Abstract (en)
[origin: WO0045304A1] A transactional store of XML documents maintains an index that can be queried at a fine grain level. The documents may be any type of XML documents (300), which encompasses a broad range of data types. A document object interface that enables an index to be built by breaking down a received document into its component parts. The index is a decomposed form of each document with pointers into the documents. The XML grammar enables the invention to maintain relationships inside documents and across documents so that the querying can be done more quickly than if documents had to be parsed with each query (310). The index also allows documents to be queried in a consistent maner. An update language integrates a new document into the existing index (320), as well as removes documents to be deleted and updates the database when a change is made.
