Denodo express license gives you a flavor of Denodo's capabilities with certain limitations. The maximum number of scheduler jobs is limited to 1. Please refer to https://community.denodo.com/docs/html/browse/6.0/platform/installation/appendix/limitations_of_the_denodo_express_license/limitations_of_the_denodo_express_license for more details.
I would recommend that you to try to use full version by requesting a free-trial or an evaluation license, as you can explore the Data virtualization potential with the Denodo Platform without any capacity restriction.You can contact firstname.lastname@example.org or fill out this contact form https://www.denodo.com/action/contact-us/ to request more information about prices if you are interested in getting a full version.
Hope this helps.
