A New Approach to Modular Database Systems

In this paper we present our approach towards a modularized database management system (DBMS) whose components can be adapted at runtime and show the modularization of a DBMS beneath the record-oriented interface as a first step. Cross-cutting concerns like transactions pose thereby a challenge that we answer with aspect-oriented programming (AOP). Finally we show the implementation techniques that enable the exchange of database modules dynamically. Particularly with regard to stateful components we define a service adaptation process that preserves and transmits the component's state.
