Cost-effective reconfiguration in ODBMSs is difficult to achieve due to the tradeoff between modularity and efficiency. Existing ODBMS designs offer limited reconfigurability because reconfigurable features are closely woven with the components to improve efficiency. This paper proposes the use of aspects - entities used by Aspect-Oriented Programming to localise cross-cutting concerns - to separate reconfigurable features from the components regardless of their granularity. This provides a cost-effective solution for both static and dynamic reconfiguration. The effectiveness of the approach is demonstrated by discussing dynamically reconfigurable instance adaptation in the SADES evolution system.
