The underlying data base has to be prepared for properly assessing the impacts of EU policy changes and market developments on agricultural income. This article presents the FADN data mining tool that reads and converts the given data for analysing the data itself and processing the data for further analysis. This tool is extendable and usable without software development skills, is free and open source and handles large data sets in an efficient and user-friendly way. It applies GAMS for aggregation, comparison, calculation, as well as for estimation of desired indicators that feed economic models.enText/Conference Paper1617-5468
