Abstract : Two different mass memories are studied for their suitability to store the data base in a command and control information-processing system. The IBM unit employs metal disk packs whereas the RCA unit uses magazines of plastic cards for the recording medium. However, analogies in their logical capabilities make it possible to use identical methods of file organization. It is shown that the equipment can be effectively utilized to process formated files on a random-access basis. Compact indexes are generated so that items can be quickly located either by name or by content. The times required for updating and searching such files are analyzed, and the advantages to be gained over conventional techniques are indicated. (Author)
