Embodiment Construction

[0075] The subject matter of the invention has been described with reference to specific features in order to satisfy statutory requirements. However, the description itself is not meant to limit the scope of this patent right. However, the inventors have contemplated that the claimed subject matter may also be implemented in other ways, to include steps or elements similar to those described in this document, in conjunction with other present or future technologies. Moreover, although the term "step" is used herein to refer to various aspects of the methods employed, the term should not be construed to imply any particular order among or between the various steps disclosed herein, unless the order of individual steps is explicitly described.

[0076] As noted above, the present invention relates to systems and methods for storing XML data in fields of user-defined types (UDTs). Fields of UDTs can be defined as XML data types; UDTs can also have other non-XML fields. Dat...

Abstract

A system and method are provided for modeling structured, semi-structured, and unstructured data all within a single instance of a user defined type (UDT) within a database store. In particular, the XML data model is extended to fields of a UDT. As a result, the properties of the XML data model-such as document order and document structure-can be preserved within instances of a UDT. Moreover, code representing object behavior (i.e., methods that can be invoked on an object in managed code) can be added to the UDT to operate on an XML field, as well as non-XML fields of the UDT. This enables a framework for adding business logic to XML data. The content model of the XML data can be optionally described using XML schema documents associated with the XML fields of the UDT.
