ABSTRACT:
A method, apparatus, and article of manufacture for managing access to an abstract database are provided. The abstract database may include a data abstraction model comprising a plurality of logical field definitions, each of the definitions comprising a logical field name, and an access method maps the logical field to a physical data field. Collectively, the physical data fields provide an indirection layer logically disposed between the data abstraction model and the underlying physical database. By providing this layer of indirection using the physical data fields, a number of enhancements to the data abstraction model may be provided. This includes providing enhancements to the security, administration, and usability of an abstract database.
