Accounts and asset ID's are unsigned 64 bit integers. As Java doesn't have explicit support for unsigned integers sometimes you get the signed representation and hence a negative number. You can convert between those using the API: [Utils API](https://ardordocs.jelurida.com/Utils#Long_Convert)

The database is internal, you cannot interact with it externally.
