In the realm of temporal databases, the concept of history is intended to include multiple time dimensions as well as multiple data models. Thus one can have, e.g., valid-time histories, transaction-time histories, and bitemporal histories. Also multi-dimensional histories can be defined from mono-dimensional ones (e.g., a bitemporal history can be seen as the transaction-time history of a valid-time history).

The term “history,” defined formally or informally, has been used in many temporal database papers, also to explain...
