Business architectureIn the business sector, business architecture is a discipline that "represents holistic, multidimensional business views of: capabilities, end‐to‐end value delivery, information, and organizational structure; and the relationships among these business views and strategies, products, policies, initiatives, and stakeholders." In application, business architecture provides a bridge between an enterprise business model and enterprise strategy on one side, and the business functionality of the enterprise on the other side.
Object lifetimeIn object-oriented programming (OOP), the object lifetime (or life cycle) of an object is the time between an object's creation and its destruction. Rules for object lifetime vary significantly between languages, in some cases between implementations of a given language, and lifetime of a particular object may vary from one run of the program to another. In some cases, object lifetime coincides with variable lifetime of a variable with that object as value (both for static variables and automatic variables), but in general, object lifetime is not tied to the lifetime of any one variable.
Enterprise engineeringEnterprise engineering is the body of knowledge, principles, and practices used to design all or part of an enterprise. An enterprise is a complex socio-technical system that comprises people, information, and technology that interact with each other and their environment in support of a common mission. One definition is: "an enterprise life-cycle oriented discipline for the identification, design, and implementation of enterprises and their continuous evolution", supported by enterprise modelling.
Federal enterprise architectureA federal enterprise architecture framework (FEAF) is the U.S. reference enterprise architecture of a federal government. It provides a common approach for the integration of strategic, business and technology management as part of organization design and performance improvement. The most familiar federal enterprise architecture is the enterprise architecture of the Federal government of the United States, the U.S. "Federal Enterprise Architecture" (FEA) and the corresponding U.S. "Federal Enterprise Architecture Framework" (FEAF).
Programmation concurrenteLa programmation concurrente est un paradigme de programmation tenant compte, dans un programme, de l'existence de plusieurs piles sémantiques qui peuvent être appelées threads, processus ou tâches. Elles sont matérialisées en machine par une pile d'exécution et un ensemble de données privées. La concurrence est indispensable lorsque l'on souhaite écrire des programmes interagissant avec le monde réel (qui est concurrent) ou tirant parti de multiples unités centrales (couplées, comme dans un système multiprocesseurs, ou distribuées, éventuellement en grille ou en grappe).
Sémantique algébrique (informatique)In computer science, algebraic semantics is a form of axiomatic semantics based on algebraic laws for describing and reasoning about program specifications in a formal manner. The syntax of an algebraic specification is formulated in two steps: (1) defining a formal signature of data types and operation symbols, and (2) interpreting the signature through sets and functions. The signature of an algebraic specification defines its formal syntax. The word "signature" is used like the concept of "key signature" in musical notation.
View modelA view model or viewpoints framework in systems engineering, software engineering, and enterprise engineering is a framework which defines a coherent set of views to be used in the construction of a system architecture, software architecture, or enterprise architecture. A view is a representation of the whole system from the perspective of a related set of concerns. Since the early 1990s there have been a number of efforts to prescribe approaches for describing and analyzing system architectures.
Référence (programmation)En programmation, une est une valeur qui est un moyen d'accéder en lecture et/ou écriture à une donnée située soit en mémoire principale soit ailleurs. Une référence n'est pas la donnée elle-même mais seulement une information sur sa localisation. Beaucoup de langages de programmation permettent l'utilisation de références, que ce soit de façon explicite ou implicite. Quand le langage de programmation dispose d'un système de typage, le type des références est construit à partir du type des objets référencés.
Langage formelUn langage formel, en mathématiques, en informatique et en linguistique, est un ensemble de mots. L'alphabet d'un langage formel est l'ensemble des symboles, lettres ou lexèmes qui servent à construire les mots du langage ; souvent, on suppose que cet alphabet est fini. La théorie des langages formels a pour objectif de décrire les langages formels. Les mots sont des suites d'éléments de cet alphabet ; les mots qui appartiennent à un langage formel particulier sont parfois appelés mots bien formés ou formules bien formées.
Systems modelingSystems modeling or system modeling is the interdisciplinary study of the use of models to conceptualize and construct systems in business and IT development. A common type of systems modeling is function modeling, with specific techniques such as the Functional Flow Block Diagram and IDEF0. These models can be extended using functional decomposition, and can be linked to requirements models for further systems partition.
