Abstract
A database system may include a memory device configured to store a database dictionary and a processor in communication with the storage device. The processor may be configured to receive a temporal user-defined function (UDF) and to store, in the database dictionary, the temporal UDF and a period of time over which to apply the temporal UDF. A method may include receiving a temporal UDF and include determining a period of time over which to apply the temporal UDF. The method may further include storing the temporal UDF and the period of time over which to apply the temporal UDF. A computer-readable medium may include instructions to receive a temporal UDF and instructions to store the temporal UDF. The computer-readable medium may further include instructions to determine a period of applicability of the temporal UDF and instructions to store the period of applicability in a storage device.
