Editing Temporal database (section)

{{short description|Database that stores information relating to past, present and future time}}
A '''temporal database''' stores data relating to time instances. It offers temporal data types and stores information relating to past, present and future time.
Temporal databases can be uni-temporal, bi-temporal or tri-temporal.

More specifically the temporal aspects usually include [[valid time]], [[transaction time]] and/or [[decision time]].

* '''Valid time''' is the time period during or event time at which a fact is true in the real world.
* '''Transaction time''' is the time at which a fact was recorded in the database.
* '''Decision time''' is the time at which the decision was made about the fact. Used to keep a history of decisions about valid times.
