Advise on your experience, please.
Need js CRUD-interface (do not know whether to put it), working with gangai on the backend (even though it does not matter).
Need to overhead in deploying the application was low.
It is important that it was easy to configure foreign key.
For example, when creating a new entry "Note" at the same time it would be possible to create a new "Category" for this entry. And so you can easily implement a search of existing records and the auto substitution of data in forms on the fly.
Key requirement - speed scanner to work (almost) out of the box and you could customize. Something similar to this https://www.smartclient.com/
