We have added KNIME, a comprehensive ETL-workbench, to our R&D toolbox. KNIME can read and write numerous file-formats and databases, while doing complex computation on data between source and target.
Besides the basic ETL-functions, KNIME has several tools for data mining, reporting and even machine learning. It is in certain ways similar to Rapid Miner, but does a lot of things that Rapid Miner does not (and vice versa). We will use KNIME together with both Rapid Miner and Gephi to prototype and visualize parts of the ASTRID-system.
