摘要

An intermediate layer for abstracting a database meta-description layer with a coupling unit and an access interface configured to be object-oriented. A connection with the database meta-description layer is implementable by the coupling unit. The database meta-description layer refers to a first database field and/or other database fields of a first database and/or other databases via a meta-description of the first database and/or other databases, via a first reference and/or other references, so that the first database and/or other databases are at least one of accessible and manipulable. The access interface comprises an object-oriented configuration so that the first database and/or other databases is/are at least one of accessible and manipulable via object-oriented calls of the access interface by using at least one of the meta-description, the first reference, and the other references.
