Atay  compared the attribute and tuple time stamping approaches in bitemporal data
* Schema evolution: It is difficult to change schema in a relational database in general, let alone when adding bitemporal data
Part two looks at the practice of employing bitemporal databases, investigating temporal transactions and queries, future assertion time, temporal requirements, bitemporal data
, and a variety of other topics.

Let M = (DS, QL) be a nontemporal data model, and let [M.sup.bi] = ([DS.sup.bi], [QL.sup.bi]) be a bitemporal data model.
1995] Given nontemporal and bitemporal data models M = (DS, QL) and [M.sup.bi] = ([DS.sup.bi], [QL.sup.bi]), data model [M.sup.bi] is a syntactically similar snapshot-reducible (S-reducible) extension of model M iff

* Support auditing requirements in highly regulated industries with bitemporal data
The confusion that has arisen in a number of bitemporal data
models between the use of the same variable in both dimensions was a prime motivation for the semantic framework that we present in the following.
