Build predictive analytics applications without coding? Yes you can, thanks to this handy toolkit from Swiss analytics vendor KNIME. KNIME's Eclipse-based visual workbench lets you drag and configure nodes on a canvas, then wire them together into workflows. KNIME supplies thousands of nodes to handle everything from data source connectivity (databases, Hive, Excel, flat files) to SQL queries, ETL transforms, data mining (supporting Weka and R), and visualization.
This year brought welcome connectors to Twitter and Google Analytics, as well as support for OpenStreetMap visualizations. The KNIME engine is open source with no crippling restrictions on data volume, memory size, or processing cores. The company also offers affordable commercial tiers that add collaboration, authentication, and performance enhancements for cluster environments.
