4.3 Summary of Space requirement results
Here we have shown one of the results from FD-based proxies’ characteristic which is percentage of space requirement for the data storage. The space requirement analysis
results shown further are total of seven sub-tables which have been separated from Taxon main table. The proxy map size was obtained by using pivot table function in MS Excel.
This pivot function directly calculates, the total number of instances present in an attribute column and also help us to analyse whether droppable proxy attribute showing one to one
relationship or one to many relationship.
