IBM Rational DOORS
Rational Dynamic Object Oriented Requirements System (DOORS) (formerly Telelogic DOORS) is a requirement management tool. 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). Rational DOORS Next Generation is now developed on the IBM Jazz platform. The Jazz platform uses Open Services for Lifecycle Collaboration (OSLC). 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. Telelogic acquired QSS in mid-2000 and IBM acquired Telelogic in 2008. History DOORS was created by Dr Richard Stevens, a researcher through the 1970's and 1980's at the European Space Agency's Research Institute (ESRIN). The first version was provided to the UK Ministry of Defenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Linux
Linux ( or ) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution, which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the importance of GNU software, causing some controversy. Popular Linux distributions include Debian, Fedora Linux, and Ubuntu, the latter of which itself consists of many different distributions and modifications, including Lubuntu and Xubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise. Desktop Linux distributions include a windowing system such as X11 or Wayland, and a desktop environment such as GNOME or KDE Plasma. Distributions intended for ser ...

Solaris (operating System)
Solaris is a proprietary Unix operating system originally developed by Sun Microsystems. After the Sun acquisition by Oracle in 2010, it was renamed Oracle Solaris. Solaris superseded the company's earlier SunOS in 1993, and became known for its scalability, especially on SPARC systems, and for originating many innovative features such as DTrace, ZFS and Time Slider. Solaris supports SPARC and x86-64 workstations and servers from Oracle and other vendors. Solaris was registered as compliant with the Single UNIX Specification until 29 April 2019. Historically, Solaris was developed as proprietary software. In June 2005, Sun Microsystems released most of the codebase under the CDDL license, and founded the OpenSolaris open-source project. With OpenSolaris, Sun wanted to build a developer and user community around the software. After the acquisition of Sun Microsystems in January 2010, Oracle decided to discontinue the OpenSolaris distribution and the development model. In Aug ...

Windows
Windows is a group of several proprietary graphical operating system families developed and marketed by Microsoft. Each family caters to a certain sector of the computing industry. For example, Windows NT for consumers, Windows Server for servers, and Windows IoT for embedded systems. Defunct Windows families include Windows 9x, Windows Mobile, and Windows Phone. The first version of Windows was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). Windows is the most popular desktop operating system in the world, with 75% market share , according to StatCounter. However, Windows is not the most used operating system when including both mobile and desktop OSes, due to Android's massive growth. , the most recent version of Windows is Windows 11 for consumer PCs and tablets, Windows 11 Enterprise for corporations, and Windows Server 2022 for servers.

Requirements Management
Requirements management is the process of documenting, analyzing, tracing, prioritizing and agreeing on requirements and then controlling change and communicating to relevant stakeholders. It is a continuous process throughout a project. A requirement is a capability to which a project outcome (product or service) should conform. Overview The purpose of requirements management is to ensure that an organization documents, verifies, and meets the needs and expectations of its customers and internal or external stakeholders. Requirements management begins with the analysis and elicitation of the objectives and constraints of the organization. Requirements management further includes supporting planning for requirements, integrating requirements and the organization for working with them (attributes for requirements), as well as relationships with other information delivering against requirements, and changes for these. The traceability thus established is used in managing requireme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telelogic
Telelogic AB was a software business headquartered in Malmö, Sweden. Telelogic was founded in 1983 as a research and development arm of Televerket, the Swedish department of telecom (now part of TeliaSonera). It was later acquired by IBM Rational, and exists under the IBM software group. Telelogic had operations in 22 countries and had been publicly traded since 1999. CEO and President in 2001 was Anders Lidbeck. On June 11, 2007, IBM announced that it had made a cash offer to acquire Telelogic. On August 29, 2007, the European Union opened an investigation into the acquisition. On March 5, 2008, European regulators approved the acquisition of Telelogic by the Swedish IBM subsidiary Watchtower AB. On April 28, 2008, IBM completed its purchase of Telelogic.

DOORS EXtension Language (DXL)
DOORS Extension Language (DXL) is a scripting language used to extend the functionality of IBM's Rational DOORS. This programming language is somewhat similar to C and C++. This language is specific to DOORS, and it has its own syntax, declaration, a forum to discuss the development, in addition to the specific reference manuals. DXL scripts were utilized to help the users of DOORS. Much of the native DOORS GUI is written in DXL. DXL is used in the client-server based "DOORS Classic"; it is not used in the newer web-based "DOORS Next Generation". Usage of DXL There are several of ways to use the DXL in the Rational DOORS. # "Editor DXL" is DXL typed into the DXL Editor window and run from there. It may or may not also be saved in some file. This DXL typically has some user interface, if only print statements. # "Menu DXL" is stored in Files and appear in DOORS windows, either the Explorer or open Module. The files must be of type , the files and the housing folders must be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open Services For Lifecycle Collaboration
Open Services for Lifecycle Collaboration (OSLC) is an open community, originally proposed in 2008, to define a set of specifications that enable integration of software development. It has evolved, and continues to evolve, to areas such as Application Lifecycle Management (ALM), Product Lifecycle Management (PLM), IT Operations and more. The intention is to make life easier for tools users and tools vendors, by making it easier for tools to work together. Organization The OSLC initiative is divided up into various OASIS TC (Organization for the Advancement of Structured Information Standards Technical Committees), as well as previously defined working groups and user groups. Each OASIS TC develops specifications in context of a specific part of the lifecycle. For example, there are OASIS TCs for Change and Configuration Management, Automation and Project Management for Contracted Delivery (Supply Chain). There is also a Core TC, which defines a common specification that is ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open Architecture
Open architecture is a type of computer architecture or software architecture intended to make adding, upgrading, and swapping components with other computers easy. For example, the IBM PC, Amiga 500 and Apple IIe have an open architecture supporting plug-in cards, whereas the Apple IIc computer has a closed architecture. Open architecture systems may use a standardized system bus such as S-100, PCI or ISA or they may incorporate a proprietary bus standard such as that used on the Apple II, with up to a dozen slots that allow multiple hardware manufacturers to produce add-ons, and for the user to freely install them. By contrast, closed architectures, if they are expandable at all, have one or two "expansion ports" using a proprietary connector design that may require a license fee from the manufacturer, or enhancements may only be installable by technicians with specialized tools or training. Computer platforms may include systems with both open and closed architectures. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rational Rhapsody
Rational Rhapsody, a modeling environment based on UML, is a visual development environment for systems engineers and software developers creating real-time or embedded systems and software.

List Of Requirements Engineering Tools
Requirements engineering tools are usually software products to ease the RE processes and allow for more systematic and formalized handling of requirements, change management and traceability. The PMI guide ''Requirements Management: A Practical Guide'' recommends that a requirements tool should be identified at the beginning of the project, as equirementstraceability can get complex and that switching tool mid-term could present a challenge. According to ISO/IEC TR 24766:2009, six major tool capabilities exist: # Requirements elicitation # Requirements analysis # Requirements specification # Requirements verification and validation # Requirements management # Other capabilities RE tool list As with most software, the vendor/owner, tool name or scope change over time. Note that compliance with, for example, safety standards such as ISO 26262 is supported by few tools directly or indirectly via specialist consulting. Unlike the major six tool capabilities (see above), the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
