dc.description.abstractAn idealized bill of materials data base is presented for the part types used in complex engineering creations. Central to such a data base is a recursive many-to-many association. It is shown how useful modes of association can be defined for the one-to-many associations of the data base and for that part of the recursive association involving any two levels of teh part type hierarchy implicit in such a data base. It is shown that SQL/N can then be used to manipulate the data base using these modes of association and natural quantifiers. The SQL/N expressions all follow the structure of corresponding English-language expressions, whereas conventional SQL expressions do not. Not covered in the report is the case of modes of association for that part of the recursive association that deals with large and unpredictable number of levels of the part type hierarchy.eng
