Abstract

This invention relates to a method for processing coded date-time string portions of a relational data base query. The method comprises the steps of (a) syntactically denoting the relative or absolute magnitude attributes of date-time strings, (b) ONTO mapping date-time strings into counterpart monotonically increasing and recursively decomposable finite number strings, (c) modifying said number strings by performing selected binary operations thereon, and (d) ONE-to-ONE mapping of said modified strings into date-time strings according to their syntactically denoted attributes.
