For more modern architectures Rational Software Architect and Rational Software Modeler were developed.

The Rational Rose family allows integration with legacy integrated development environments or languages. A 2007 book noted that other UML tools are also capable of this, the list including Borland Together, ESS-Model, BlueJ, and Fujaba. Rational Rose could also use source-based reverse engineering the combination of this capability with source generation from diagrams was dubbed roundtrip engineering. It simplifies the complex process of software design, creating a 'blueprint' for construction of software systems. The Unified Modeling Language (UML) is the industry-standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems. The Rational Rose family of products is a set of UML modeling tools for software design. With the Rational June 2006 Product Release, IBM withdrew the “XDE” family of products and introduced the Rational Rose family of products as replacements. The Rational Software division of IBM, which previously produced Rational Rose, wrote this software. Rational Rose XDE, an 'eXtended Development Environment' for software developers, integrates with Microsoft Visual Studio.
