 There is a top-level YAML object ``jdbc`` that contains a list of database resources. Each resource is an object that has at least the fields ``name``, ``type`` and ``url``. The ``name`` should be the part of the JNDI name that comes after ``jdbc/``. If the JNDI name of the database is ``jdbc/myDatabase``, then the ``name`` field should be ``myDatabase``. The fields ``type`` and ``url`` define how to reach the database. Sometimes the ``properties`` field is added, see below. Credentials to access the database should be provided through the combination of fields ``username`` and ``password``, or through ``authalias`` if the username and the password are treated as secrets (see :ref:`deploymentCredentials`).
