Abstract:

Suggestions which will be useful in the problem area of reference to large files of information are presented. The conclusions which are drawn or may be implied are presented below. While the problem of indexing is essentially the same in any file reference problem and equipment, it can always be solved by keeping the exhaustive index - not the file - up to date. In some cases it is possible to appreciably reduce the size of the index which may be required. Undue emphasis on the factor of pipeline time may be removed in favor of increased emphasis on that of traffic rate. This may be done with the same equipment in three different ways, namely 1 by approximating the optimum balance of emphasis within a single problem 2 by emphasizing one of these factors in one problem and another in another problem, within the same framework of mechanization and 3 by emphasizing one factor, e.g., traffic rate, throughout the problem and handling requests requiring an emphasis of pipeline time reduction as special cases, emphasizing this factor.
