I know, that it is a big selling point to use Cuba Studio, but in my case, the application is not so big, that if I will use the “10” free entities and adding some more entities, it will be fine…
my question is, are there some good tutorials/documentations, which explain how to develop by source?
I think it is much heavier, because if I need to create an User-Interface, I will need to do all manually etc, also writing the SQL-Scripts when creating Entity?
You can start from CUBA CLI tutorial: CUBA CLI Quick Start - YouTube It enables you to build applications from scratch using command line and your Java IDE.
