Seasonal adjustment is an everyday step of the statistical business process in the official statistics, therefore a proper system that guarantees the high quality results is important for every National Statistical Institute (NSI). The Hungarian Central Statistical Office (hereinafter referred to as: HCSO) operates a centralized internal system for seasonal adjustment. The aim of Plutus (a new developed system described) is to help the collaboration of colleagues from different departments and solve the problem of increased data set, especially during the annual model revisions. Plutus is a system of databases with a user friendly interface, fully metadata driven. The biggest advantage of Plutus is that the whole system is more transparent than before and the collected metainformation can be linked to any other metadata object. This tool is now under construction and the planned implementation is the next annual revision period in 2019.
