Introduction to RTC
The IBM Rational Team Concert (RTC), as a software collaborative development tool, is gradually being used in the production of large projects, maintaining a large project organization and methodically managing each development task, thus laying a solid foundation for creating high-quality software products.
The RTC provides an integrated environment throughout the development process, including requirements definition, iteration
