IBM Engineering Requirements Management DOORS (Dynamic Object Oriented Requirements System) (formerly Telelogic DOORS, then Rational DOORS) is a requirements 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.
The Common Lisp Object System (CLOS) is the facility for object-oriented programming in ANSI Common Lisp. CLOS is a powerful dynamic object system which differs radically from the OOP facilities found in more static languages such as C++ or Java .
An object-oriented operating system [1] is an operating system that is designed, structured, and operated using object-oriented programming principles.. An object-oriented operating system is in contrast to an object-oriented user interface or programming framework, which can be run on a non-object-oriented operating system like DOS or Unix.
Requirements traceability is a sub-discipline of requirements management within software development and systems engineering.Traceability as a general term is defined by the IEEE Systems and Software Engineering Vocabulary [1] as (1) the degree to which a relationship can be established between two or more products of the development process, especially products having a predecessor-successor ...
One of the requirements for automated code generation is to precisely model the actions within the finite-state machines used to express dynamic behaviour of Shlaer–Mellor objects. Shlaer–Mellor is unique amongst object-oriented analysis methods in expressing such sequential behavior graphically as Action Data Flow Diagrams (ADFDs).
Object-oriented modeling enables this by producing abstract and accessible descriptions of both system requirements and designs, i.e. models that define their essential structures and behaviors like processes and objects, which are important and valuable development assets with higher abstraction levels above concrete and complex source code.
Objects are the run-time entities in an object-oriented system. They may represent a person, a place, a bank account, a table of data, or any item that the program has to handle. There have been several attempts at formalizing the concepts used in object-oriented programming.
The topology is a description of the run-time structure of a system. [10] An object-oriented program is a complex and dynamic network of objects, in the same sense that relationships between real-world objects are complex and dynamic. Consider a waiter at a restaurant.
