+Z MySQL Deferred DA
+
+ This is the Z MySQL database deferred adapter product for the
+ Z Object Publishing Environment. It is based on
+ ZMySQLDA and follows the same API and installation
+ procedure.
+
+ The main difference with ZMySQLDA is that the execution
+ of SQL expressions is deferred and executed during the Zope
+ commit time rather than immediately. This allows for example
+ to group INSERT and DELETE statements in a very short amount of
+ time, which reduces risks of lock. It also allows to use
+ MyISAM tables without raising useless exception messages related
+ to the non transactional nature of MyISAM.
+
+ ** IMPORTANT **
+
+ SELECT expressions will not work in deferred mode

+<p>
+ The connection string used for Z MySQL Database Connection
+ is of the form:
+<pre>
+ [*lock] [+/-][database][@host[:port]] [user [password [unix_socket]]]
+</pre>
+ or typically:
+<pre>
+ database user password
+</pre>
+ to use a MySQL server on localhost via the standard UNIX socket.
+ Only specify host if the server is on a remote system. You can
+ use a non-standard port, if necessary. Hint: To use a non-standard
+ port on the local system, use 127.0.0.1 for the host instead of
+ localhost.
+<p>
+ Either a database or a host or both must be specified.
+<p>
+ If the UNIX socket is in a non-standard location, you can specify
+ the full path to it after the password.
+<p>
+ A '-' in front of the database tells ZMySQLDA to not use Zope's
+ Transaction Manager, even if the server supports transactions. A
+ '+' in front of the database tells ZMySQLDA that it must use
+ transactions; an exception will be raised if they are not
+ supported by the server. If neither '-' or '+' are present, then
+ transactions will be enabled if the server supports them. If you
+ are using non-transaction safe tables (TSTs) on a server that
+ supports TSTs, use '-'. If you require transactions, use '+'. If
+ you aren't sure, don't use either.
+<p>
+ *<em>lock</em> at the begining of the connection string means to
+ psuedo-transactional. When the transaction begins, it will acquire
+ a lock on the server named <em>lock</em> (i.e. MYLOCK). When the
+ transaction commits, the lock will be released. If the transaction
+ is aborted and restarted, which can happen due to a ConflictError,
+ you'll get an error in the logs, and inconsistent data. In this
+ respect, it's equivalent to transactions turned off.
+<p>
+ Transactions are highly recommended. Using a named lock in
+ conjunctions with transactions is probably pointless.

+ The connection string used for Z MySQL Database Connection
+ is of the form:
+<pre>
+ [*lock] [+/-][database][@host[:port]] [user [password [unix_socket]]]
+</pre>
+ or typically:
+<pre>
+ database user password
+</pre>
+ to use a MySQL server on localhost via the standard UNIX socket.
+ Only specify host if the server is on a remote system. You can
+ use a non-standard port, if necessary. Hint: To use a non-standard
+ port on the local system, use 127.0.0.1 for the host instead of
+ localhost.
+<p>
+ Either a database or a host or both must be specified.
+<p>
+ If the UNIX socket is in a non-standard location, you can specify
+ the full path to it after the password.
+<p>
+ A '-' in front of the database tells ZMySQLDA to not use Zope's
+ Transaction Manager, even if the server supports transactions. A
+ '+' in front of the database tells ZMySQLDA that it must use
+ transactions; an exception will be raised if they are not
+ supported by the server. If neither '-' or '+' are present, then
+ transactions will be enabled if the server supports them. If you
+ are using non-transaction safe tables (TSTs) on a server that
+ supports TSTs, use '-'. If you require transactions, use '+'. If
+ you aren't sure, don't use either.
+<p>
+ *<em>lock</em> at the begining of the connection string means to
+ psuedo-transactional. When the transaction begins, it will acquire
+ a lock on the server named <em>lock</em> (i.e. MYLOCK). When the
+ transaction commits, the lock will be released. If the transaction
+ is aborted and restarted, which can happen due to a ConflictError,
+ you'll get an error in the logs, and inconsistent data. In this
+ respect, it's equivalent to transactions turned off.
+<p>
+ Transactions are highly recommended. Using a named lock in
+ conjunctions with transactions is probably pointless.
