Oracle Launches Free Database Version

The ranks of free databases gained another recruit Tuesday with the general availability of Oracle 10g XE.

Available as a 150-Mbyte download via Oracle’s Web site, 10g XE is compatible with the bigger-iron Oracle databases, the Redwood Shores, Calif.-based company has said.

Like competitive offerings from Microsoft and IBM, 10g XE has hardware and memory constraints. It’s designed for use on one-processor machines and handles up to 4 Gbytes of user data and up to 1 Gbyte of memory.

Developers are the target audience for 10g XE, according to Mark Townsend, senior director of database product management at Oracle.

"There are four clear development communities,” Townsend said. “For those who use the Java stack, we provide all the JDBC drivers so you can write stored procedures in Java. For the .Net stack, there is a Visual Studio add-on so you can write in CLR [Microsoft's Common Language Runtime]. There are optimized PHP drivers and also a built-in application Express development environment."
