A method, apparatus, and computer-readable medium are provided for storing data such that the data automatically changes to remain current over time. In one embodiment, a database server stores metadata in association with data that is stored in a database. The metadata specifies a time and a manner in which the data should change. On, near, or after the specified time, the database server reads the metadata to determine that the specified time is satisfied. In response to determining that the specified time has been satisfied, the database server changes the data stored in the database in the specified manner.
