Which knowledge is required to develop an cuba application from source?

Hi,

I want to ask,
which knowledge is required to develop an cuba application?
I think it is Java Persistence API? Or what knowledge do the developer need for this all? ORM?

Thank you

I think most people with a working knowledge of Spring an ORM will be fine. I didn’t know a thing about Vaadin when I started.

I’d start with the example projects to get a basic understanding, and then use the excellent documentation and the forums for specific stuff.

Ok,

Thanks,
I will take a look
