.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This is the entry point in the mysql-specific object-relational
persistence backend.
.PP
This backend makes use of Mysql extensions \s-1SELECT GET_LOCK, SELECT
RELEASE_LOCK\s0 and \s-1LAST_INSERT_ID\s0 to safely allocate object ids in the
absence of transactions.
.PP
The vanilla Relational backend may not be used with Mysql databases in
multiprogramming context.
.SH "METHODS"
.IX Header "METHODS"
This backend does not add any methods; for a description of
available methods, see Tangram::Relational.
