A data dictionary is repository of metadata (information about data), such as its meaning, relationships to other data, origin, usage and format. The dictionary assists company management, database administrators, systems analysts and application programmers in effectively planning, controlling and evaluating the collection, storage and use of data.

Oracle's data dictionary is stored in the SYS schema in SYSTEM tablepace.
