Abstract: The present invention provides “XML Schema Collections” and methods and systems for using the same. XML data is typically stored as an XML instance, each of which should conform to a “schema” according to a desired goal. An XML schema provides identification and organization for the data supplied by an XML instance. XML Schema Collections are collections of one or more XML schema namespaces. An storage location designated for storage of XML data, such as an XML column in a relational database, can be “typed” with an XML Schema Collection object, allowing that storage location to store XML instances that conform to more than one XML schema. XML Schema Collections provide increased data storage versatility, and facilitation of data searches.

Abstract: A computerized system and method for transforming the results of a query into a hierarchical information stream, such as an eXtensible Markup Language (XML) data stream is disclosed. A database server receives a query and generates a rowset. A rowset processor, using the mode specified in the query, processes the rowset and query to generate the XML data stream. For the “auto 1” mode, the rowset processor transforms a rowset into an XML data stream using primary-foreign key information specified in the query to determine nesting. For the “auto2” mode, the rowset processor transforms a rowset into an XML data stream using table ordering information included in the query to determine nesting. For the “explicit” mode, the rowset processor transforms a rowset into an XML data stream using the explicit organizational information specified in the query.

Abstract: A method and apparatus is disclosed for transforming hierarchical information into a rowset and for transforming a rowset into hierarchical information. In transforming hierarchical information, such as an XML data file, into a rowset, a parser parses the XML data file to form an active store. A query processor, after receiving a query including a number of metaproperties, processes data from the XML active store to form a rowset. The rowset can be processed further using a query language, such as the Structured Query Language (SQL). After processing, the rowset can be converted back into an XML data file using an XML formatter. An overflow feature facilitates the addition of text data to the rowset. A fusion feature facilitates defining a relationship between different data items in the rowset such that they can be merged into a single data element as the rowset is converted into an XML data file.

Abstract: Users and programmers can load semi-structured hierarchical data, such as XML data, of arbitrary size and structure into relational database tables using an schema such as an SQL-annotated XML schema. The schema describes how XML data maps into base tables and fields, including complex one-to-many and many-to-many relationships. The hierarchical data is streamed into the relational database tables in a single operation.
