== Oracle Vector support
Oracle engineers contributed the support for vector data types and functions to the `hibernate-vector` module
to use with Oracle database version 23.4 and newer.
For further information about vectors, consult the link:https://docs.oracle.com/en/database/oracle/oracle-database/23/vecse/overview-node.html[Oracle documentation].
