+The ``make`` method receives one argument: the struct ``key`` containing the primary key value of an element of :ref:`key source <keysource>` to be worked on.

+Transactions are formed using the methods ``startTransaction``, ``cancelTransaction``, and ``commitTransaction`` of a connection object. 
+A connection object may obtained from any table object.
+
+For example, the following code inserts matching entries for the master table ``Session`` and its part table ``SessionExperimenter``.
+
+.. code-block:: matlab
+
+    % get the connection object 
+    session = Session
+    connection = session.conn
+
+    % insert Session and Session.Experimenter entries in a transaction
+    connection.startTransaction
+    try 
+        key.subject_id = animal_id; 
+        key.session_time = session_time;
+
+        session_entry = key;
+        session_entry.brain_region = region;
+        insert(Session, session_entry) 
+
+        experimenter_entry = key;
+        experimenter_entry.experimenter = username;
+        insert(SessionExperimenter, experiment_entry)
+        connection.commitTransaction
+    catch 
+        connection.cancelTransaction
+    end
+
+
+Here, to external observers, both inserts will take effect together only upon exiting from the ``try-catch`` block or will not have any effect at all.
+For example, if the second insert fails due to an error, the first insert will be rolled back.
