not with performance related issues.

My 2 cents..
Before you actually start worrying about the performance tuning of database
parameters or hardware required for the DB, you should make sure that you
have designed the database properly by taking care of all aspects like
normalisation, denormalisation (??). If you don't take care
This is an interesting subject area.
In a data warehousing environment, one tends to adopt table structures such
as snowflake layouts which lead to improved performance.
Createing a perfect normalised database design may well lead to performance
issues. The more joins you have, by far the worse

The effects of a bad logical DB design will effect you the most only in the

Hey all,
I've got a production database that made up of all MyISAM tables. I'd

You will need to make sure you have innodb configured in the my.cnf
file and you have enough space built for it in the shared table
space. InnoDB also needs it's own memory pool, so make sure you give
it enough memory. For day to day issues there is no problem doing
