Definition - What does Temporal Database mean?
A temporal database is a database that has certain features that support time-sensitive status for entries. Where some databases are considered current databases and only support factual data considered valid at the time of use, a temporal database can establish at what times certain entries are accurate.
Techopedia explains Temporal Database
Technologies including Oracle, Teradata and SQL have versions with temporal feature support.
Different uses of temporal databases require radically different types of development. For example, in a database of customer, patient or citizen data, indicators for individual people will follow a kind of life cycle timeline that can be created according to time frames for comment life events. By contrast, many industrial processes using temporal databases need extremely short valid time and transaction time indicators. These are rigidly implemented depending on length of time for various parts of business processes.
