Are there (significant) overheads for using structures?
Suppose we wish to store a very large number of facts like:
person(name(surname, firstname), date_of_birth(dd, mm, yyyy)).
Are the predicate names 'name' and 'date_of_birth' being stored repeatedly? Is it more efficient to flatten the structure to:
person(surname,firstname,dd,mm,yyyy)
Is indexing affected by the structure?
Also, do the overheads depend on the prolog implementation used?
Many thanks,
PJ
