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:
A method and apparatus for compensating for deficiencies existing in programs to assist a user through installing a program. Polling the status of jobs requested by the user of a workstation is done so that the user may eventually be provided with status reports regarding the jobs being executed. The user can set parameters during loading of SMPE libraries, install, migrate, fallback, remigrate and update procedures for the program. An indication is provided to a user of a workstation as steps of a task have been completed by the user. The health of catalog and directory databases may be verified before a migrate procedure is performed. The user of the program can be informed regarding parameters whose default values have changed, which parameters are of particular concern to the specific user.
