An interface system for accessing data stored in corresponding storage elements includes at least a zone (2) for storing data proper and a zone (3) for storing a data dictionary defining structurally the database, the data base being accessible through elements forming an access interface (4). The elements forming an access interface are associated with a dictionary (5) of interface defining descriptors, accessible through elements modifying its content to enable programming of the configuration of the elements forming an interface to be programmed by creating, suppressing or modifying descriptors in the dictionary (5) of interface defining descriptors and elements (6) are provided for automatically updating the dictionary (3) of data structurally defining the database to adapt the latter to the programmed configuration of the elements forming an interface.
