MySQL, one of the high-profile open source vendors, will hold its MySQL Users Conference 2005 event next week in Santa Clara, Calif.In addition to tutorials listed as “Sold Out” by MySQL, the agenda features sessions on MySQL clustering, the MySQL 5.0 database and the LAMP stack (Linux, Apache, MySQL, Perl/Python/PHP). Attendees also will hear about Mono, which is an open source development platform based on Microsoft .Net technology. In attracting show sponsors such as Dell, Hewlett-Packard, IBM and Intel, it is clear that interest in MySQL has gone beyond just the free, open source realm and has spread into the commercial arena. MySQL, though, still has its work cut out for it competing against high-powered commercial databases such as Oracle and IBM DB2 and open source rivals such as PostgreSQL. Next week, though, promises to be a MySQL technology lovefest not unlike what Java will get at the annual JavaOne show in June or what the IBM Rational platform will receive at the IBM Rational Software Development Conference 2005 next month. MySQL is clearly coming of age. Technology Industry
