The public EXAMPLES Server is a public server made available by KNIME to provide help and examples. It is accessible via anonymous login from the KNIME Workbench. So here in the KNIME Explorer, above your local workspace, you can see this EXAMPLES item. This takes you to the EXAMPLES Server. So right-click and select “Login”, no password is required. Once you are logged in, you can see a large list of example workflows organized by KNIME functionality or by use case. Workflows for real use cases are available in 50_Applications. Here there are all the workflows for real use cases. Double clicking a workflow opens it temporarily in the workflow editor. In the annotation at the top, you find the description of the task and possibly you find useful references. The workflow of course is write-protected. So you can execute it, you can change it, but you cannot save it on the EXAMPLES Server. The only option to save the changes that you have made to this workflow is to use “File” and then the “Save as” option. Even if you closed the workflow and you say that you want to save it, it is going to take you to this “Save as” dialog. If you don’t save, all the changes that you have made to the workflow are going to be lost. Sometimes, let’s go through some of the older workflows, when you open an old workflow you find a deprecated node. Deprecated nodes are old nodes and should not be used anymore. A new version of the same node is available in the node repository and that should be used. However, back-compatibility is guaranteed in KNIME, and to guarantee the repeatability of older workflows, old and outdated nodes are still kept available for older workflows. These older and outdated nodes are still working. They are just marked as “deprecated” to show you that a new better working version is available in the Node Repository. But they should still be working. So I’ve shown you here all the examples that are available in the EXAMPLES Server, and you should just find the example that better suits your problem. For example, we said, if you have a churn prediction problem, then what you should do you should go to the 50_Applications, the folder with the real use case examples. Select 18_Churn_Prediction. Probably you need both of them, and you just drag and drop the selected workflow or group of workflows into your local workspace. And now you have it in your space, and you can change and save and adapt it to your own data, and your own problem.
