Mistress Mnemos
this huge computer system was rumored to have been maintained by the Alliance as an intergalactic database. C-3PO was able to interface with Mnemos to gather information on Blackhole. Located on one of the most secret safeworlds the Alliance maintained, Mnemos had a feminine personality and was given a good deal of programming on etiquette and protocol. She required that any being making inquiries of her memory bank follow set procedures, and omit any irrelevant or unnecessary details. While the knowledge contained within Mnemos's memory banks was generally believed to be extensive, it was only as good as the data that it was given. Much of the information on Luke Skywalker's family history, for example, was misleading or simply wrong.
