The main data source of FARMIS is the national or the European FADN1.This paper demonstrates, how the Data Management System for FADN Data in FAL is organized to ensure a secure and convenient data handling either in the case of data access by researchers for individual analysis (TESTNET) or in the case of running the FARM Group Model using the Data-Adapter-Software WFARMIS.enText/Conference Paper1617-5468
