+
+As soon as an entity class inherits from another entity class, inheritance has to 
+be declared by adding the appropriate configuration for the root entity.

+When using the ``EntityManager#getReference()`` method, you need to be aware
+of a few peculiarities.
+
+At the best case, the ORM can avoid querying the database at all. But, that
+also means that this method will not throw an exception when an invalid value

+not checked and there is no guarantee that the requested entity instance even

 How do I set the charset and collation for MySQL tables?

-You can't set these values with attributes, annotations or inside yml or

-collation you should configure MySQL to use it as default charset, or
-create the database with charset and collation details. This way they

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Regarding existing rows in many-to-many join tables that refer to
+an entity being removed, the following applies.
+
+When the entity being removed does not declare the many-to-many association
+itself (that is, the many-to-many association is unidirectional and
+the entity is on the inverse side), the ORM has no reasonable way to
+detect associations targeting the entity's class. Thus, no ORM-level handling
+of join-table rows is attempted and database-level constraints apply.
+In case of database-level ``ON DELETE RESTRICT`` constraints, the
+``EntityManager#flush()`` operation may abort and a ``ConstraintViolationException``
+may be thrown. No in-memory collections will be modified in this case.
+With ``ON DELETE CASCADE``, the RDBMS will take care of removing rows
+from join tables.
+
+When the entity being removed is part of bi-directional many-to-many
+association, either as the owning or inverse side, the ORM will
+delete rows from join tables before removing the entity itself. That means
+database-level ``ON DELETE RESTRICT`` constraints on join tables are not
+effective, since the join table rows are removed first. Removal of join table
+rows happens through specialized methods in entity and collection persister
+classes and take one query per entity and join table. In case the association
+uses a ``@JoinColumn`` configuration with ``onDelete="CASCADE"``, instead
+of using a dedicated ``DELETE`` query the database-level operation will be
+relied upon.
+
+.. note::
+
+    In case you rely on database-level ``ON DELETE RESTRICT`` constraints,
+    be aware that by making many-to-many associations bidirectional the
+    assumed protection may be lost.
