MaIN.NET currently can be directly conncted to one of supported database providers, however this code now adds only to maintainability of project and seems not very needed. As its not broadly used.

We should keep in memory persistance, but for future refs user can store it in own data layer
Perhaps in the future we can consider creating separate nuget package dedicated for that

Ambition is to also cleanup MaINSettings that currently allow to set configurations etc.
End user should not notice the difference, and code should be prepared to be extendable for future improvements on that area
