Sorry Alan, What u described below is exactly what i want to do.. if given x, y as two datatums and such that f(x) --> y, given y can we determine f or x?
Assuming the x, y and f are stored in the database, then we can be able to write queries to search/extract for the f's that are responsible for the 'y' or use links, database catalogs etc Thanks for the help.
