This workflow blends data between two different relational DBMS in KNIME Analytics Platform. It focuses on two common relational database systems, i.e. MS Access and H2. Why these two? Both are relatively easy to use, and used mainly in individual departments or small-to-medium business sectors. The data is a standard baseball encyclopedia and it is available in text form, in .csv file, and in relational database format. Data are available at http://www.seanlahman.com/baseball-archive/statistics/.
