Abstract
A logical type language data processing method which includes making a plurality of different application programs each using a predicate type fact database and/or a predicate type rule database; inputting a predicate type question with respect to the application programs to process data by unification and back tracking processes; making and storing a common predicate type fact database which is used commonly by the different application programs; putting a symbol to predicates of the different application programs to indicate that the predicates with the symbol are common type predicates which should use the common predicate type fact database; and accessing the common predicate type fact database if any of the predicates with the symbols is read out during execution of the application programs.
