IBM, which bought Rational last year, used Rational's user conference in the US last week to launch its Atlantic suite.
The Atlantic tools include modelling and testing elements as well as remote collaboration built around the Clearcase client. Some of the tools launched under the Atlantic umbrella will use elements of IBM's Eclipse range of products, including the open source Eclipse integrated development environment.
Mike Devlin, general manager at Rational Software, said, "The Eclipse environment can be seen as the integration framework for the technology base of IBM's and Rational's tools."
Some of the tools launched at the conference will be in an open source format, but IBM did not release further details. The key features of Atlantic are product integration and compatibility. The tools will offer support for Java-based products and IBM's Websphere development products.
