This paper describes a method of managing statistical data and its derivation process through a statistical database management system.
Statistical data can be divided into two categories: individual data and summary data. In a large census, the variety of data summaries becomes numerous and the number of statistical tables also becomes numerous.
Actualization of a statistical database which can manage a large number of statistical tables has been desired. But, it is not clear which functions are important for statistical data amnagement. To say the least, functions in existing DBMS is considered insufficient.
This paper examines the characteristics of the statistical data management and proposes a derivation graph for managing the derivation process of statistical data.
