Oryx::DBI::Association::Hash - DBI implementation of hash associations
This provdes an implementation of hash associations with connections made via
This is just a quick run-down of implementation details as of this writing to
help introduce users to the database internals. These details may change with
future releases and might have changed since this documentation was written.
A hash association is stored into the database as a separate table named for the
tables linked and the role of the link:
within the table there will be exactly three fields:
- This will be the ID field for the source table in the link.
- This will be the ID field for the target table in the link.
- This is the key used to identify the target from the source. This will be
unique for the tuple (source_id, _key).
