Type: Biological database New Facet based on Instances of this Class

A current database is a conventional database that stores data that is valid now. For example, if a user inserts "John Smith" into the Staff table of a current database, this asserts that the fact is valid now and until it is subsequently deleted. By contrast, a temporal database qualifies each row with a valid time stamp, valid time period or valid time interval. For example, we can assert the fact that "John Smith" was a member of staff during the period 1 June 2001 and now. Current databases are the most common type of database in use today. The concept of now is discussed in Clifford et alia (1997).
