Immortal DB

The Immortal DB project began in the fall of 2002. This project's goal is to provide the infrastructure for saving and indexing all prior states of a database. Foundational work for this effort has been published: on indexing versions, and on choosing timestamps. We have built a prototype system that includes indexing, version compression, and bad user transaction recovery. A major goal has been to provide performance close to that of an unversioned database.
