The logical structure of a database is described by the schema, which is a blueprint or plan for how the database is organized and how data is stored and accessed. The dictionary is a collection of metadata that describes the structure and contents of the database. The subschema is a subset of the schema that defines how a particular user or application accesses the database. The internal level is the lowest level of the database architecture, which defines how data is stored and accessed at the physical level.
