A data model that allows multiple interpretations facilitates this process. In that case it is absolutely irrelevant whether the first parts have been implemented in a database or whether they exist in the design stage. It is much easier to extend the class of solvable problems. Practical experiences have shown that problems can be solved which cannot be solved using other approaches. It is also easy to reach that goal because the data language consists of orthogonal components.
Queries are also easily adaptable.
To be able to prove the promises of semantic modeling in practice, Xplain DBMS has been developed. It started as a simple research product, meanwhile it has been extended and improved. End users see a system consisting of 50 menus with 400 options altogether. Kernel Including elementary data storage functions for transposed files. Main Containing menu software and the delegation of control to other modules.
