Tub file
From Wikipedia, the free encyclopedia
The tub file was an early, primitive random access memory technology in which pre-punched punch cards that contained frequently used information were stored in a file for reuse. Usually such tub files would contain a series of related data — one for each item sold in a store, for example — so that data would be easy to find and reuse.
