Techniques of Search File Organization
David Lefkovitz · 1969
I n C hapter V the two-step retrieval process of Decoding and File search was described, and it was indicated that these two processes were relatively independent. As a further demonstration of this independence Chapter VI presented detailed descriptions of these de- coders with minimal reference to or contingencies upon the data file organization. Only in one case, the randomizer associated with Fig. 33, was there a restriction placed on the file structure design. Thus, the designer is relatively free to select a decoder, based almost entirely upon the criteria outlined in the last chapter. Similarly, the selection of a data file structure is independent of the decoder.
