碩士 === 國立交通大學 === 資訊工程研究所 === 82 === OODB, due to its flexibility and expressing power, is believed to be the next generation database. Furthermore, the continuing progress and the decrease in price in secondary storage make the inclusion of temporal information support an attractive feature. We believe that, to extend the potential usefulness of OODBs beyond its existing applications, we must also support temporal features in OODBs. In this thesis, we study the storage structures for rollback object-oriented database management systems. We also run a series of simulations to compare their performance under different loads and analyze the storage requirement of these data structures. In addition, we suggest clustering strategies for these storage structures to improve the performance. Finally, we propose a storage structure for single object evolution in temporal databases management systems.
