    It was termed "georelational" because in keeping with the principles of relational databases, the geometry and attributes could be joined by matching each shape with a row in the table using a key, such as the row number or an ID number. [20] The spatial database (also called the object-based model [20]) first appeared in the 1990s.

  8. Derived unique key per transaction - Wikipedia

    en.wikipedia.org/wiki/Derived_unique_key_per...

    A key is retrieved from the set of “Future Keys” This is used to encrypt the message, creating a cryptogram. An identifier known as the “Key Serial Number” (KSN) is returned from the encrypting device, along with the cryptogram. The KSN is formed from the device's unique identifier, and an internal transaction counter.
