of the Dissertation XML-Based Support for Database Histories and Document Versions by University of California, Los Angeles, 2004 Professor Carlo Zaniolo, Chair Current database systems do not provide e#ective means for archiving the database history and querying past snapshots of the database and its temporal evolution. Better support for temporal applications by database systems represents an important objective that is di#cult to achieve, since it requires an integrated solution for technical problems that are challenging on their own, including (i) expressive temporal representations and data models, (ii) powerful languages for temporal queries and snapshot queries, (iii) indexing, clustering and query optimization techniques for managing temporal information e#ciently, and (iv) architectures that bring together the di#erent pieces of enabling technology into a robust system.
