Abstract

Economic time series files are quite different in structure from cross-sectional ones. Database systems of the former are structured in a simple form, each record consisting of a single time series being independent of another, while those of the 1atter are generally organized in a complicated form, each record containing a number of tiems being interrelated with another. However, some complexities exist which are proper to the time series. Associated with each economic item are 20 time series depending on terms of value (current or constant), unit of time (monthly, quarterly, etc) and seasonal adjustment. Though the database systems of economic time series seem to be simple in their structure, yet they have to be such as to handle these relationships associated with the time series. In this paper we present one such database system, which is built in the STEPS system.
