A dynamic system for creating and managing a database (4) includes at least one server device (3, 6) in which a server software part (10) is installed and contains the database (4) and at least one client device (5, 7) in which a client software part (20) is installed. The client device (5, 7) is able to connect to the server device to access the database (4). The data contained in the database (4) are organized into dynamic tables according to a hierarchical tree structure (30). The server software part (10) includes an abstractor module (13) which converts the hierarchical structure (30) into a relational structure (31) by using metadata (32) which contain information concerning the structure of the tables and of the fields. |
