US Classification:

7071041, 707101, 707102, 717117, 715513, 715523

Abstract:

A method and system are provided for extracting a valid, self-contained fragment for a node in a XML document stored in a database management system. An XML index is used to identify a location in which XML fragment data corresponding to the node is located. Ancestors of the node are identified and examined for any information needed for the proper interpretation of the fragment. If an ancestor node contains such needed information, this information is patched into the XML fragment to ensure that the fragment is a valid, self-contained XML fragment.

US Classification:

707101, 707E17124, 715234

Abstract:

A method and system are provided for flexibly sectioning XML documents stored in a relational database system. The method includes obtaining a set of sectioning rules; receiving an XML document that is to be stored in the relational database system; and identifying a storage location for each node in the XML document based on the set of sectioning rules. The sectioning rules can also be used to determine which tables in the relational database should be queried when a query is received, and to determine which tables in the relational database should be updated when a command to update stored XML data is received.

US Classification:

707 2, 707E17041, 707101

Abstract:

A method and system are provided for determining whether a given path is an indexed path of XML documents stored in a database management system. A finite state machine is built using the path subsetting rules specified by a user. The finite state machine is traversed using the given path. If any accepting states are reached during the traversal of the finite state machine, the given path is determined to matching the path subsetting rules.

US Classification:

707 3, 707E17012, 707E17083

Abstract:

Techniques are provided for indexing XML documents. According to one embodiment, a PATH table created for storing one row for each indexed node of the XML documents. The PATH table row for a node includes (1) information for locating the XML document that contains the node, (2) information that identifies the path of the node, and (3) information that identifies the position of the node within the hierarchical structure of the XML document that contains the node. If the node is associated with the value, then the PATH table row for the node may also include the value. Use of the PATH table to answer XPath queries is facilitated by secondary indexes.

Abstract:

A search result is modified to include a predetermined number of channels within a predetermined number of a plurality of entries in the search result. The search result is generated in response to a search query. The search result is modified to comprise a predetermined number of channels within a predetermined number of the plurality of entries. The modified search result is updated based on the plurality of entries and a subset of the updated modified search result is selected to be presented in response to the search query. The subset of the updated modified search result comprises the channel and at least one selection of data content.
