Optimization of Signature File Parameters for Database with Varying Record Lengths
A new method for ranking the output of the superimposed variation of the signature file method (SC/SF) is presented. The method is termed 'Binary Ranking' and assigns a value ('B-rank value') to each block candidacy of the signature file output in a way which reflects the credibility of the signature to stand in place of the corresponding real text. In order to measure the performance of the proposed technique, a simulation environment based on a Relational Database Management System is established. Binary Ranking is found to be promising for a category of real-life applications and allows for future enhancements.
