Abstract
A method and system are provided for handling within a database system data items that are associated with data types that are not supported by the database language used to the database system. The data types are registered with the database system by storing, in the database, metadata that indicates the structure, physical layout, and constraints that apply to the data types. The database system uses the structure and physical layout information to access individual elements of data items. The database system validates data items using the constraint information, which includes constraints that dictate what values are valid for certain elements based on what values are supplied for other elements. Data items associated with many different data types may be stored in the same table. Applications can access the data items through a transformation view that transforms the data items from their native format to a format expected by the applications.
