摘要：A Temporal Database is a database with built-in support for handling time sensitive data. Usually, databases store information only about current state, and not about past states. For example, in an employee database if the address or salary of a particular person changes, the database gets updated and the old value is no longer there. However for many applications, it is important to maintain the past or historical values and the time at which the data was updated. That is, the knowledge of evolution is required. That is where temporal databases are useful. It stores information about the past, present and future. Any data that is time dependent is called the temporal data and these are stored in temporal databases.Temporal Databases store information about states of the real world across time. Temporal Database is a database with built-in support for handling data involving time.
