How to map classes to different sqlite database files using ODB?

I created 3 classes, that are currently mapped to one database.

I want to create another database so 1 class will map to "db1" and the second to "db2".

I thougt that the right way sould be adding something to the pragma :

 #pragma db object ("db1")

elsewise, how can we know where each class will be mapped?

Can anyone advise how to do it? And if the compilationd shpuld be changed?

    ODB_COMPILER  -d sqlite --generate-query --generate-schema person.h && cp person-odb.cxx person-odb.cpp
