Description
Temporal database systems are systems that provide special support for storing, querying, and updating historical and/or future data.
Current DBMSs provide essentially no temporal features at all, but this situation is likely to change soon for a variety of reasons;
in fact, temporal databases are virtually certain to become important sooner rather than later, in the commercial world as well as in
academia. This book provides an in-depth description of the foundations and principles on which those temporal DBMSs will be built. These
foundations and principles are firmly rooted in the relational model of data; thus, they represent an evolutionary step, not a revolutionary
one, and they will stand the test of time.
