Embodiment Construction

[0028] The present invention will now be described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It is evident, however, that the invention may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate descriptions thereof.

[0029] As used in this patent application, the terms "component" and "system" refer to a computer-related entity, which may be hardware, a combination of hardware and software, software, or software in execution. For example, a component may be, but is not limited to being, a process running on a processor, a processor, a hard drive, multiple storage drives (optical and / or magnetic storage media), an object, executable code, a th...

Abstract

Translation architecture that facilitates translation between schema data and relational structures. The architecture includes a translation component that consumes schema data ( e . g ., an XML schema) that includes a schema structure, validates the schema structure, and persists in memory a representation of the schema as a relational format. Since schemas are shredded into tables, instance validation loads only the necessary components to perform validation. During validation, only parts of the schema that are used are loaded and cached. A schema cache stores the in-memory representation of schema optimized for instance validation. Schema components are loaded from metadata into main memory as read-only objects such that multiple users can use the in-memory objects for validation, query processing, query optimization and storage optimization of XML instance data .

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 60 / 619,043, filed October 15, 2004, entitled "MAPPING OF XML SCHEMA DATA INTO RELATIONAL DATABASE STRUCTURES" ”, which patent application is hereby incorporated by reference in its entirety. Background technique [0003] XML (Extensible Markup Language) provides a standard way of marking data so that the data can be read and interpreted by various web browsers. Given the massive proliferation of web hosts and applications on global communication networks such as the Internet, XML documents are widely used in everyday transactions. [0004] A Document Type Definition (DTD) is a technique for defining the document structure of an XML document in terms of a list of legal elements or building blocks. From a DTD perspective, all XML documents (and HTML documents) are made up of the following simple building blocks: elements, tags (for marking elemen...
