Holistic Data Transfers, known as HDTs, was a way of writing datafiles in an information short hand. Designed by a combination of droids, programmers, and computer linguists, HDTs had an element of artificial intelligence built in, and the memory usage was small but sophisticated. HDTs allowed users to access more data on a given subject than was actually available by making informed "guesses" about the information it did possess. The more data the HDT had to work with, the more accurate the deduced information was.
