Thanks for your interest and your question. Yes, I feel we are easier to use than most of our competitors too, just one of many differentiators you will find.
I want to make sure we are clear that we are talking about Qlik Sense Cloud and not just any licensed Qlik product installed on a cloud based host.
If that is the case, our new product Qlik Sense Cloud - is used for freely sharing Qlik Sense apps (up to 5 people) only at the moment - and soon will have creation in the cloud capabilities but only from files that you can upload. I just want to make sure you understand the difference in the terminology for what you refereed to as Qlik Cloud.
In answer to your question, yes - we load data from the source into our associated index model which is part of the app. a .qvf file (Qlik Sense). The data is compressed up to a 10x and allows for very fast on the fly aggregation and selection interaction. No it does not maintain a connection. This .qvf file is then uploaded to the Qlik Sense Cloud. There isn't a live connection to the source data. In order to refresh, you would do that manually and locally using Qlik Sense Desktop and then re-upload the app. They would see the data as is from your last refresh of the data in the app.
Note: A licenses version of Qlik Sense Enterprise has a scheduler component that will automatically refresh the data in the app from the source. There are also incremental loading techniques that will only load / update the app with the changed / new data.
Qlik Sense Cloud at the moment does not support Extensions objects - which are mostly visualizations and form objects to help improve the interaction within the app. A SQL Data Source is considered a data source not an extension. You would connect to the SQL data source using Qlik Sense Desktop, create your app and then upload to the Qlik Sense Cloud.
