Main Schema-External Schema Interaction in Hierarchically Organized Data Bases

Summary: Defines a class of external schemas derivable from a tree-structured main schema in hierarchical databases. The class's properties enable a processing interface that lets predicates on the external schema be evaluated inside an occurrence structure disciplined by the main schema.
