Thank you for your inquiry.
Yes currently GroupDocs.Annotation for .NET demo example is working only with JSON file as data source. We have logged your request for demo example with SQL database and our concerned team will look into it. Once we get any update from example team regarding demo example with SQL Database we will inform you here.
Thank you for your patience.
I also would like to store all JSON data to database.
Are there any updates on this?

Thank you for you inquiry and patience.
Sorry for the delays. We got response from product team regarding this issue. Next Generation GroupDocs.Annotation is storage-agnostic API, this means that it does not support any specific storage (i.e Oracle, MS SQL Server and so on). But it provides abstract interface that you can implement, and for storing data in specific storage. Please click here to view more details.
