ABSTRACT:
A method for manipulating a database of data and rules stored in a computer system where the computer operates in accordance with object-coded rules defined by a specified object code grammar. The computer including storage means for storing data and object-coded rules in tables in conformance with a storage architecture, control means for storing, retrieving and deleting data and object-coded rules from the tables, translator means for translating source-coded rules into object-coded rules, detranslator means for translating object-coded rules into source-coded rules and scanner means for determining lexical validity of an object-coded rule according to the grammar. The method first comprising the ordered steps of entering into the computer a first source-coded rule; storing the first source-coded rule into tables in the storage means; translating the first source-coded rule into a first object-coded rule; storing the first object-coded rule into the tables in the storage means; and discarding the first source-coded rule from the tables in the storage means. Secondly, the method comprises the steps of retrieving an object-coded rule from the tables in the storage means; translating the object-coded rule into a second source-coded rule; editing the second source-coded rule; storing the second source-coded rule, as edited, into the tables in the storage means; translating the second source-coded rule into a second object-coded rule; storing the second object-coded rule into the tables in the storage means and discarding the original object-coded rule and the second source-coded rule from the tables in the storage means. The method further requires that each translating step determines lexical validity or invalidity of the object-coded rule translated from the source-coded rule; that each storing step conditions the storage of an object-coded rule in the tables in the storage means upon the determination of validity of the object-coded rule to be stored and each discarding step conditions the discarding of the first source-coded rule upon the storing of said first object-coded rule into the tables in the storage means and of the original object-coded rule and the second source-coded rule upon the storing of the second object-coded rule in the tables in the storage means.
