A mapping mechanism for objects persistence in multivalued database

Abstract

Objects persistence has been popular recently since it has become a necessary practice to shuttle objects between in-memory and in-storage status. Most researchers focus on objects to relational data model mapping but few on objects to multivalued data model (O/M). Nevertheless, existing mapping mechanisms are either hard to be extended or difficult to be managed. This paper presents a mechanism for mapping from objects to multivalued databases. A detailed mapping solution is exhibited. Besides, an interactive mapping configuration facility has been developed to ease the configuration instead of manual scripts editing. Experiments show that around 92% of the time is saved to configure the domain classes mapping by using the configuration facility of the proposed persistence mechanism in contrast to manual editing used in other similar mapping mechanisms. Simulation results show that this mapping mechanism not only shortens the overall development period, but also comparatively easy to be managed and extended.
