Re: What are the data source limitations of using Qlik Sense Desktop? (free version)
It has exactly the same limits as the non-free Qlik Sense Enterprise version. If you have an odbc or oledb driver for your data source then you can connect with it. For some special sources (for example web apis for the twitters, facebooks etc of this world) you need a special connector. Some of those are not free. But that applies to both Qlik Sense Desktop and Qlik Sense Enterprise.
