I have extensive knowledge of this excellent open-source database. This was our primary database for all of the web applications at Pason Systems, the largest of which had 200 GB of data. I spent a week in Houston in early 2002 taking a MySQL training course covering security, disaster prevention and recovery, replication, transactions, and system optimization. I also use this database for all of my personal software projects requiring a database. I am very impressed with this database as it definately becoming enterprise capable.     (Since: 1999)
