Rational Dynamic Object Oriented Requirements System (DOORS) (formerly Telelogic DOORS) is a requirement management tool.[4] It is a client–server application, with a Windows-only client and servers for Linux, Windows, and Solaris. There is also a web client, DOORS Web Access.

Rational DOORS has its own programming language called DOORS eXtension Language (DXL).[5]

Rational DOORS Next Generation is now developed on the IBM Jazz platform. The Jazz platform uses Open Services for Lifecycle Collaboration (OSLC).[6]

In order to complete its functionality, Rational DOORS has an open architecture that supports third-party plugins.

DOORS was originally published by Quality Systems and Software Ltd (QSS) in 1991.[7] Telelogic acquired QSS in mid-2000.[8]
