An SQL, Front-End for Non-monotonic Inheritance and De-referencingf SQL and demonstrate that they are sufficient and powerful enough for modeling classes, non-monotonic inheritance and de-referencing. In particular, we show that simple tweaking of SQL with . helps capture these OO features cleanly and empowers application developers with a powerful knowledge modeling tool.

Capturing Multi-level Models in a Two-Level Formal Modeling Techniquetwo-level scheme, and hence cannot be used for multi-level models directly. We show here how a multi-level model in ML2 can be transformed into a two-level specification in the formal modeling technique Alloy, thereby leveraging the Alloy analyzer to multi-level models.
