mORMot Open Source

I'm starting with Delphi.

I have found some confidence with RAD and written some Object Pascal code.

Now, I would like to invest my time by learning, from the beginning, how to use an ORM. So I invested a few hours reading mORMot's documentation and running the Samples code on GitHub.

What I need is a very simple program to store customers orders (namely: basic CRUD operations and edit data in master-detail mode using a FMX grid).

Are there any examples closest to my needs? (I ask for that because I suppose this is a common needs ...)

Thanks.
