distribution substantially, according to the company. The MySQL Network subscription service starts at US$595 and costs US$4,995 per database per year for round-the-clock support.
MySQL also intends to distribute a release candidate for MySQL 5.0 next week and make the release generally available in the fall, said Zack Urlocker, vice president of marketing at MySQL. That update will include a number of features, including the ability to handle distributed transactions using the XA standard.
MySQL is benefiting from the growing interest in the so-called LAMP stack of open-source components for building business applications, Urlocker said. Rather than purchase Java or Microsoft .Net development tools, corporate customers are building new applications on the LAMP combination of Linux; Apache Web server; MySQL; and PHP, Python or Perl scripting languages.

A number of smaller companies are betting on LAMP as a viable stack on which to build add-ons and tools. MySQL's booth at the LinuxWorld conference is hosting a number of smaller companies, including ActiveGrid and Liquid Systems, that have built their products on the LAMP combination.
Meanwhile, another start-up, EnterpriseDB, is taking on the corporate database market but using a slightly different tack.
The company, launched in May, has built tools to ease the migration from Oracle databases to PostgreSQL. Similarly, later this year EnterpriseDB intends to create compatibility with the querying languages for Microsoft's SQL Server.
The database is available for free download and use for development and testing. Once an application is put into production, EnterpriseDB will charge customers between US$1,000 and US$5,000 per year per processor for technical support services using a commercial license. A multicore processor will be considered a single CPU for licensing.
The company also announced that PostgreSQL engineers Alvaro Herrera, David Cramer and Jonah Harris will work for EnterpriseDB, while continuing their PostgreSQL development work. EnterpriseDB also said it will sponsor a project to build standard-compliant stored procedures in PostgreSQL.
The employee moves and code donations are meant to raise EnterpriseDB's standing in the PostgreSQL open-source community, said company founder and CEO Andy Astor.
"Bluntly put, we are based on Postgres. If Postgres doesn't succeed, we don't exist as a company," Astor said. "It's in our strong interest for Postgres to be a wildly successful database."
Astor said EnterpriseDB expects to be cash-flow positive within the
