Within this paper, he described a whole new procedure for storing and dealing with huge databases. In place of records being saved in some kind of connected list of absolutely free-sort information as in CODASYL, Codd's strategy was to work with a "table" of set-size data, with each table utilized for another type of entity. A connected-list procedure could well be really inefficient when storing "sparse" databases where by a few of the facts for just about any a single file may very well be left vacant.
