Pentaho Data Integration is one of the open source products we offer, and supports many different data sources. The product provides Extract, Transform and Load (ETL) capabilities. You can easily write a transformation that connects, merges, and creates a result from multiple databases and flat files at once. In Pentaho Reporting 3.5, you can connect directly to a transformation, making it possible to generate a report based on mulitple databases.
