  1. The KNIME workbench — what are the key points?

    Search the Node Repository rather than browsing thousands of nodes · Every node is drag, connect, configure, execute · Port shape indicates data type; only matching types connect Read the lesson

  2. Node states and execution — what are the key points?

    Red means not configured, yellow ready, green executed · A previously green node turning red usually means a column was renamed upstream · Reconfiguring a node resets it and everything downstream Read the lesson

  3. Reading and writing files — what are the key points?

    Readers can take a folder plus a filter to read many files at once · Type guessing scans a limited number of rows — set types explicitly for identifiers · Check the writer overwrite policy or reruns duplicate data Read the lesson
