Purchasing licenses You can purchase new licenses if your current product license is about to expire or to acquire additional product licenses for team members. Administrator guide Typically, a user with the administrator role is responsible for certain tasks including installation, configuration, and integration of the product.

Installing the product Installing the product involves verifying requirements, planning, performing pre-installation tasks and managing licenses. Installing This section provides the instructions for installing the product as well as installation verification. Planning the installation After verifying hardware, software, and user privilege requirements, plan the features and software that you want to install.
Pre-installation Tasks for Studio Before you install the product, you need to prepare or configure your computer. Installing the product from the launchpad The launchpad program provides you with a single location to view release information and start the installation process. Verifying the installation When the installation process is complete, a message confirms the success of the process.
Updating software You can search for product updates and install the updates for your product. Rational Machines was founded by Paul Levy and Mike Devlin in to provide tools to expand the use of modern software engineering practices, particularly explicit modular architecture and iterative development.
First released in , the Rational Environment was an integrated development environment for the Ada programming language, which provided good support for abstraction through strong typing. Its goal was to provide the productivity benefits associated with academic single-user programming environments to teams of developers developing mission-critical applications that could execute on a range of computing platforms.
The Rational Environment was organized around a persistent intermediate representation DIANA , providing users with syntactic and semantic completion, incremental compilation, and integrated configuration management and version control. To overcome a conflict between strong typing and iterative development that produced recompilation times proportional to system size rather than size-of-change, the Rational Environment supported the definition of subsystems with explicit architectural imports and exports; this mechanism later proved useful in protecting application architectures from inadvertent degradation.
The Environment's Command Window mechanism made it easy to directly invoke Ada functions and procedures, which encouraged developer-driven unit testing. The Rational Environment ran on custom hardware, the Rational R, which implemented a high-level architecture optimized for execution of Ada programs in general and the Rational Environment in particular.
The horizontally-microprogrammed R provided two independent bit data paths, permitting simultaneous computation and type checking.
Memory was organized as a single-level store; a bit virtual address presented to the memory system either immediately returned data, or triggered a page fault handled by the processor's microcode.
The company's name was later changed from 'Rational Machines' to Rational Software Corporation RATL to avoid emphasizing this proprietary hardware when Rational merged with Verdix Corporation, a public company that developed Ada compilers, on 30 March Rational provided code generators and the cross-debuggers for then-popular instruction set architectures such as the VAX, Motorola , and x86; much of this was accomplished through a partnership with Tartan Labs, founded by Bill Wulf to commercialize his work on optimizing code generators semi-automatically produced from architecture descriptions PQCC.
