Object modelIn computing, object model has two related but distinct meanings: The properties of objects in general in a specific computer programming language, technology, notation or methodology that uses them. Examples are the object models of Java, the Component Object Model (COM), or Object-Modeling Technique (OMT). Such object models are usually defined using concepts such as class, generic function, message, inheritance, polymorphism, and encapsulation.
Code sourcevignette|redresse|Copie papier d'un code source en Fortran des années 1970, imprimé sur du , dédié aux fichiers textes. En informatique, le code source est un texte qui présente les instructions composant un programme sous une forme lisible, telles qu'elles ont été écrites dans un langage de programmation. Le code source se matérialise généralement sous la forme d'un ensemble de fichiers texte. Le code source est souvent traduit — par un assembleur ou un compilateur — en code binaire composé d'instructions exécutables par le processeur.
Associate degreeL'Associate Degree, Associate's Degree (traduit comme « Diplôme d'associé »), Associate diploma ou Grade d'associé au Canada est un diplôme américain, canadien, australien ou néerlandais attribué aux étudiants qui ont validé avec succès un cursus d'études supérieures d'une durée de deux ans. Il est accordé par certains colleges ou collèges communautaires (community colleges) et par certaines universités.
Master's degreeA master's degree (from Latin magister) is a postgraduate academic degree awarded by universities or colleges upon completion of a course of study demonstrating mastery or a high-order overview of a specific field of study or area of professional practice. A master's degree normally requires previous study at the bachelor's level, either as a separate degree or as part of an integrated course.
Bachelor's degreeA bachelor's degree (from Middle Latin baccalaureus) or baccalaureate (from Modern Latin baccalaureatus) is an undergraduate academic degree awarded by colleges and universities upon completion of a course of study lasting three to six years (depending on institution and academic discipline). The two most common bachelor's degrees are the Bachelor of Arts (BA) and the Bachelor of Science (BS or BSc).
British degree abbreviationsDegree abbreviations are used as an alternative way to specify an academic degree instead of spelling out the title in full, such as in reference books such as Who's Who and on business cards. Many degree titles have more than one possible abbreviation, with the abbreviation used varying between different universities. In the UK it is normal not to punctuate abbreviations for degrees with full stops (e.g. "BSc" rather than "B.Sc."), although this is done at some universities.
Strong and weak typingIn computer programming, one of the many ways that programming languages are colloquially classified is whether the language's type system makes it strongly typed or weakly typed (loosely typed). However, there is no precise technical definition of what the terms mean and different authors disagree about the implied meaning of the terms and the relative rankings of the "strength" of the type systems of mainstream programming languages.
Machine virtuelle Javavignette|Machine virtuelle Java - Spécification Java 7 La machine virtuelle Java (en anglais Java virtual machine, abr. JVM) est un appareil informatique fictif qui exécute des programmes compilés sous forme de bytecode Java. L'appareil est simulé par un logiciel spécifique à chaque plateforme ou couple (machine/système d’exploitation) et permet aux applications Java compilées en bytecode de produire les mêmes résultats quelle que soit la plate-forme, tant que celle-ci est pourvue de la machine virtuelle Java adéquate.
Substructural type systemSubstructural type systems are a family of type systems analogous to substructural logics where one or more of the structural rules are absent or only allowed under controlled circumstances. Such systems are useful for constraining access to system resources such as , locks, and memory by keeping track of changes of state that occur and preventing invalid states. Several type systems have emerged by discarding some of the structural rules of exchange, weakening, and contraction: Ordered type systems (discard exchange, weakening and contraction): Every variable is used exactly once in the order it was introduced.
Base de données orientée objetEn informatique, une base de données à objets (anglais object database) est un stock d'informations groupées sous forme de collections d'objets persistants. Une base de données est un ensemble d'informations connexes stockées dans un dispositif informatique. Dans une base de données à objets les informations sont regroupées sous forme d'objets : un conteneur logique qui englobe des informations et des traitements relatifs à une chose du monde réel.
