'''Rational Software Modeler''' (RSM), made by [[IBM]]'s [[Rational Software]] division, is a [[Unified Modeling Language]] (UML) 2.0-based visual modeling and design tool.<ref name=iw/> Rational Software Modeler is based on the [[Eclipse (software)|Eclipse]] [[open source software|open-source]] [[software framework]]<ref name=iw/> and is used for visual modeling and [[model-driven development]] (MDD) with [[Unified Modeling Language|UML]] for creating applications and web services.  IBM ceased marketing Rational Software Modeler in 2010 and ended support for it in 2015.<ref name="end of support" />  Much of the same functionality is now available through [[Rational Software Architect]].

==Overview==
The capabilities of the last major release (Version 7) of Rational Software Modeler include:
# Support for [[Unified Modeling Language|UML]] version 2.1<ref>{{Cite web |title=Rational Software Modeler product overview |url=https://www.ibm.com/docs/en/rsm/7.5.0?topic=modeler-rational-software-product-overview |access-date=2025-05-21 |website=www.ibm.com |language=en-us}}</ref>
# Support for model-to-model transformations
# Model management for parallel development and architectural re-factoring, e.g., split, combine, compare and merge models and model fragments
# Support for application of design patterns

It is integrated with other IBM Rational Software tools, such as [[Rational ClearCase|ClearCase]] configuration management and [[Rational ClearQuest|ClearQuest]] exception handling (defect reports and change requests).

RSM is engineered as a plugin that sits on top of the open-source [[Eclipse (software)|Eclipse]] development platform. RSM can be installed either on top of an existing Eclipse v3.2 installation, or as a new Eclipse v3.2 instance.

As RSM is Eclipse-based, it can use third-party Eclipse plugins, as well as plugins specifically for Rational tools.

==History==
{{unreferenced section|date=November 2015}}
[[Rational Software]] has a long history in application modeling, beginning in the early 1990s with the work of [[Grady Booch]], [[James Rumbaugh]] and [[Ivar Jacobson]]. They combined competing modeling approaches to form what eventually became the [[Unified Modeling Language]].

Rational Software's first visual modeling and development tool was [[Rational Rose]], a stand-alone modeling tool that integrated the [[application programming interface]] (API) level with third-party [[Integrated Development Environments]] (IDEs) in order to support a variety of programming languages and other implementation technologies.

While Rational Rose was an important step towards bringing [[Model-driven development]] (MDD) closer to practicing software developers, it was found that only a small fraction of developers used modeling on a routine basis. A key problem was identified – developers didn't like to leave their IDE. They wanted visual modeling to be integrated — not with their IDE, but rather ''inside'' their IDE.

Rational responded to this need in 2002 with [[Rational Rose|IBM Rational XDE]] software, providing a development environment for the programming technologies emerging at the time: Java and [[Microsoft .NET]]. IBM Rational XDE was characterized as the next generation of IBM Rational Rose — not a new version of it (hence the name change), and not necessarily a replacement for Rose (since IBM Rational XDE was purposefully restricted to support only a select number of IDEs and implementation technologies). However, with each addition of a tool or capability came another point-to-point integration requirement. As more and more capabilities were added, Rational began to reach the practical limits of this style of tool integration.

For the next-generation MDD products, model-driven development functions were built on top of Eclipse to form a more complete MDD tool. IBM Rational Software Architect, IBM Rational Software Modeler and IBM Rational Systems Developer were the result of these changes; merging the silos that previously defined modeling, development and code analysis into a more integrated design.
