trait BasicBackend extends AnyRef
Backend for the basic database and session handling features.
Concrete backends like JdbcBackend
extend this type and provide concrete
types for Database
, DatabaseFactory
and Session
.

string interpolator. In Java 15 and later,formatted
resolves to the new method in String which has reversed parameters.
