Ingres r3 for Windows and Linux is available today under the Computer Associates Trusted Open Source License. Under the terms of this license, customers can download the database for free, view the source code, and integrate it with other products that are also offered under the same Trusted Open Source License. CA also announced four paid support options for Ingres to generate revenue for the free product. Ingres currently has around 15,000 customers. CA earlier announced a $1 million development contest to spur interest in its database. The company hopes to draw customers away from MySQL, Sybase, and an IBM open-source project called Derby. CA says Ingres' features compete with those of Oracle's massive database suite.
