Abstract A method is described by which data in a database system are named using sets. The sets exist in an n-dimensional data space in which each axis represents a homogeneous set and all axes (sets) are orthogonal. Data are represented as mathematical functions of relationships between the sets. Data are named using an ordered combination of the names of the sets. An executable language is used to describe relationships between the sets and to query the database. This methodology lends itself quite conveniently to APL and currently forms the foundation for a robust commercial application performing electronic data interchange (EDI) translation.
