    摘要: Provided are techniques for processing structured content within Large Object (LOB) data that is stored in a column of a database table. Structural metadata describing structures that each define a different format of the structured content is stored. A request for data in the database table is received. The structural metadata is used to create an empty result set with columns defined by at least two of the structures. For each row of data in the database table that includes LOB data, control data is used to identify one of the structures to be applied to the structured content within the LOB data stored in that row of data, and the structured content within the LOB data in that row of data is mapped to the columns in the result set based on the identified one of the structures. The result set is returned.

    摘要: The capturing of rich database metadata includes: capturing partitioned column metadata of a database as mappings defined by a plurality of constraint statements; defining non-standard user-defined types of the database according to a schema; defining physical representations of columns of the database according to the schema; and storing the defined mappings, the defined user-defined types, and the defined physical representations of columns to a catalog of the database. Application enumerated data values in the database may also be defined according to the XML schema and stored to the catalog of the database. In this manner, the database management system may manage application constraints, user-defined types, and physical representations of data for applications referencing the same database using the metadata information stored in the catalog of the database.

    摘要: An apparatus, system, and method are provided for defining a metadata schema to facilitate passing data between an XML document and a hierarchical database. The invention includes a database accessor, a document accessor, and an association module. The database accessor accesses a database schema indicative of database field names and a hierarchical structure for a hierarchical database. The document accessor accesses a document schema that defines the hierarchical structure, content data syntax, and semantics of valid, well-formed, XML documents that can be passed into and out of the hierarchical database. The document schema also includes at least one XML element name that maps to a corresponding database field name in the database schema. The association module associates the database schema and the document schema to provide a metadata schema that enables data to be passed between an XML document and the hierarchical database.

    摘要: An apparatus, system, and method are provided for passing data between an XML document and a hierarchical database. The apparatus, system, and method include a hierarchical database, a metadata schema, and a mapping module. The hierarchical database comprises a conventional hierarchical database, such as IMS. The metadata schema is derived from the hierarchical database. The metadata schema includes a first representation representative of the hierarchical structure of the hierarchical database, a second representation representative of the hierarchical structure of XML documents valid for passing into and out of the hierarchical database, one or more database field names, and one or more XML element names that map to the one or more database field names. The mapping module passes data between the XML document and the hierarchical database using the metadata schema.
