NAME
Tie::RDBM::Cached

DESCRIPTION
Tie::RDBM::Cached should support any database supported by Tie::RDBM.

Please see the pod documentation in the module itself for more information. This is a very early release of this module and I am expecting quite a few bugs.

Feel free to contact me at harry@hjackson.org if you have any problems queries or sugestions.

REQUIREMENTS
This module dependa upon Tie::RDBM and DBI. Please read the documentation from Tie::RDBM as this has more information on ways to use this module.

INSTALLATION
perl Makefile.PL
make test DRIVER=[Driver] DB=[dbname] USER=user PASS=password make install

The "make test" is optional.

If you are using Postgres please ensure the following syntax where "test" is the name of the database.

make test DRIVER=Pg DB=dbname=test USER=user PASS=password

LIMITATIONS
This module will only add performance gains for quite specific tasks involving two columns in a table, one of which should be a primary key or be unique. For inserts and deletes this module will have a detrimental affect on performance. Please see the Tie::RDBM documentation for more information about this.

If you are required to carry out a lot of updates repeatedly to the same record then this module will offer significant performance gains over Tie::RDBM. I am a fan of DBI, please make sure you know why you want to use this rather than the DBI interface or the Tie::RDBM mmodule.

TROUBLESHOOTING
If you get an error when using this module and you have tried Tie::RDBM in its place please send me the code and the error output and I will try to help you. Please do not send me any errors before testing the Tie::RDBM module first because this is what I will do.

The latest version of this module is available on CPAN.

Further Information can be found in the following documentation:
