The alternative may be to have a "database layer" that hides the 'implementation' from the application. As an example, let me talk about the bulky GUID (UUID): It is human readable as 36 hex characters and dashes. It _could_ be stored in BINARY(16) much more compactly. The 'layer' could hide that from the user.

IPv6 (the new, more complicated, IP-address naming system) also could benefit from a layer to turn what humans would like as VARCHAR(39) into BINARY(16). The former cannot be used in range queries; the latter can.

Would you care to share with me your "datatype"? I might like to invent some clever trick for you.
