Hello from a research assistant getting deeper into KNIME :-)

Hello everyone,

I'm a student research assistant from the north of Germany (Master’s degree programme in Sustainable Engineering, as well as Production and Logistics), currently working on a project that involves building components as open-source. Before this project, I had no prior experience with KNIME, but I got started a few months ago and have been learning by doing (through hands-on practice) ever since.

I began with the basics (readers, filters, joins, group-bys) and have since worked my way into flow variables, CASE switches, Java Snippets, widgets, and loops. I'm currently designing the validation part of my workflow (checking column counts, column names, missing values, and time formats before the actual analysis) and trying to make it robust and user-friendly (e.g. automatic user outputs, error messages and improvements / corrections). I'll post my specific design questions in separate threads and would greatly appreciate feedback or patterns from more experienced KNIMErs :-)

Besides getting concrete help, I'm hoping to learn how experienced users structure larger workflows, especially when it comes to user interaction and error handling.

Looking forward to learning from and with you! 👋
Ole
