Abstract

The invention relates to the accessing and modification of the relational data base tables as a parameter-passing medium among picture data structures. This avoids parameter-passing only by way of the coding hierarchy found in picture decomposition/composition routines. Clauses are used by an interpreter to select subsets of existing tables. Tables may be modified by the addition or change of columns.
