This paper describes the design of a Data Dictionary/Directory(DD/D) system of a statistical database system HSDB which is under development at Hiroshima University. The DD/D system which originally was a facility to support database administrators in managing data structures (metadata) has been considered as a tool for controlling the whole database environment. On a statistical database system, the metadata and the environment are different from those on a conventional one. Some researchers have discussed the statistical DD/D system but they have only dealt with special metadata of the statistical data. A statistical DD/D system should also be considered as a tool for managing the whole statistical environment where a statistical database is accessed by many non-specified statistical analysts who do not really know the contents of the data. New statistical programs and packages are also being developed by other researchers rather than analysts as usual. Therefore, it is necessary for DD/D to manage information about data collection, familiar statistics, derivation of data, and statistical programs. We realized the statistical DD/D system with three approaches; 1) adding new entities into the DD/D, 2) adding new attributes into the structure of the DD/D and 3) expanding software facilities on the DD/D. The realized system effectively helps data collectors, database administrators, statistical analysts and program developers.
