Hi Nico,
You can separate the data by creating xpath constraints on entity level. You can find more information about this here.
Hi Nico,
You can create a multi-tenant app with one single Mendix instance. You need need to create a tenant (company) entity in your domain model, then associate other entities to your tenant and create xpath constraints.
You also need the license pool manager module from the appstore, to create license pools for each company separetely and handle users accordingly. Check https://appstore.home.mendix.com/link/app/179//License-Pool-Manager
Hope this helps.
Hi Nico,
You can have a look at the multi tenant administration module in the Mendix AppStore. I think this will help you with your project.
You can find it here: https://appstore.home.mendix.com/link/app/80498/
Please let me know if you have any questions.
