You could build some REST services to expose your data to Qlik View. Looks like Qlik View can consume REST data sources.
I believe Qlik supports OData as well:
I’ve worked on a project where they push data to Qlik via rest services and then iframe Qlik dashboards in their mendix app.
As Mike and Eric said, you can either use REST or OData to get your data from Mendix to Qlik.
You can use a rest service indeed, however query parameters in Qlik Sense are not recognized in Mendix restulting in Mendix allways reading the full table, congesting and slowing down the performance drastically.
Up until now there is no solution available in either Qlik Sense nor Mendix, a work around is to use a qvd table file and load the tables during off working hours, and loading the data from the qvd table file in Qlik Sense.
