Abstract
This thesis documents the process of developing a framework for communicating with an RDBMS for applications that have a limited need for database query capabilities are characterized of by being “forms-over-data”. The motivation for making this framework is rooted in a subset of the impedance mismatch problem together with issues that are associated with using data from an RDBMS in an objectoriented environment. This led us to automatic code generation of a specialized API that implements four different design patterns together with a synchronization mechanism that enables a lightweight concurrency model in keeping local data consistent with changes in the RDBMS. The VDO framework is documented in detail and an evaluation of the it is given, where we state our achievements together with the limitations it has. The thesis concludes that the designed framework assists an application developer by reducing unnecessary reproduction of effort, when developing applications that need to safely interact with an RDBMS together with other clients.
