just some excerpts will suffice.
see that station ‘wxrep’ has its own database ‘weewx.sdb’ but also external
database ‘vantage.sdb’ referred to using data_binding ‘vantage'

[Databases]
# A SQLite database is simply a single file.
[[archive_sqlite]]
database_name = weewx.sdb
database_type = SQLite
[[vantage_sqlite]]
database_name = vantage.sdb
database_type = SQLite
… … … …
[DataBindings]
[[wx_binding]]
# The database must match one of the sections in [Databases].
# This is likely to be the only option you would want to change.
database = archive_sqlite
# The name of the table within the database.
table_name = archive
# The manager handles aggregation of data for historical summaries.
manager = weewx.manager.DaySummaryManager
# The schema defines the structure of the database.
# It is *only* used when the database is created.
