Dictionary Cache Concepts

Information stored in the data dictionary cache includes
  1. usernames,
  2. segment information,
  3. profile data,

The dictionary cache also stores descriptive information, or metadata, about schema objects. Oracle uses this metadata when parsing SQL cursors or during the compilation of PL/SQL programs
