Patent number: 7885980Abstract: Techniques are provided for indexing XML documents using path subsetting. According to one embodiment, a PATH table created for storing one row for each indexed node of the XML documents using user-defined criteria. The user-defined criteria are used to determine which nodes of XML documents to included in The PATH TABLE. 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. Use of the user defined criteria is transparent to any query improves DML indexes overhead costs.Type: GrantFiled: April 10, 2006Date of Patent: February 8, 2011Assignee: Oracle International CorporationInventors: Asha Tarachandani, Sivasankaran Chandrasekar, Nipun Agarwal, Eric Sedlar, Ravi Murthy, Anh-Tuan Tran

Patent number: 7680764Abstract: Populating an XML index is parallelized, providing both inter-document and intra-document parallelism, by using multiple pull-type parser processes to parse respective XML documents in parallel and to call respective ‘instances’ of the function that generates the index entries based on parsed XML node information. The function is configured to operate according to a cursor-type interface model, whereby each function instance can operate on one node at a time in a controlled pull manner rather than in an uncontrolled streaming manner. Hence, the index load procedure flow can be in the control of an application or routine, via the pull parsers, rather than in the control of a serial stream-based parser.Type: GrantFiled: June 21, 2006Date of Patent: March 16, 2010Assignee: Oracle International CorporationInventors: Sivansankaran Chandrasekar, Anh-Tuan Tran, Ravi Murthy, Nipun Agarwal

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.Type: GrantFiled: July 2, 2004Date of Patent: March 3, 2009Assignee: Oracle International CorporationInventors: Sivasankaran Chandrasekar, Ravi Murthy, Ashish Thusoo, Anh-Tuan Tran, Sreedhar Mukkamalla, Eric Sedlar, Nipun Agarwal

Patent number: 6859808Abstract: A mapping mechanism for a primary B+tree in a database management system. The primary B+tree includes a plurality of rows. The mapping mechanism includes introducing a mapping table that includes a plurality of rows, including a row for each row of the primary B+tree, and that stores the logical identifier of the corresponding primary B+tree row. In addition, reverse mapping is provided by augmenting a primary B+tree to include in each primary B+tree row a physical row identifier of the corresponding mapping table row. An auxiliary structure created on a primary B+tree can make use of the proposed mapping mechanism. Specifically, the auxiliary structures refers to primary B+tree rows indirectly by storing the physical row identifier of the corresponding mapping table row.Type: GrantFiled: May 31, 2001Date of Patent: February 22, 2005Assignee: Oracle International CorporationInventors: Eugene I.
