Proving Event-B Models with Reusable Generic Lemmas

Abstract

UML-B provides a graphical notation for Event-B that enables formal development in a UML style. UB2DB is a tool that translates UML-B models to relational database implementations in SQL. The UB2DB tool is implemented as a plugin for Rodin, an extensible toolkit for Event-B. This paper presents the current version of UB2DB that translates the main components of UML-B class diagrams to SQL code. The generated SQL code defines a database and provides procedures that manipulate it. The UB2DB tool exploits the Eclipse Modeling Framework (EMF) to realise the required model transformation. The current tool provides the basis for a more comprehensive tool that will provide support for a broader range of UML-B features and support a variety of database components and constraints.
