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.
Mapping objet-relationnelUn mapping objet-relationnel (en anglais object-relational mapping ou ORM) est un type de programme informatique qui se place en interface entre un programme applicatif et une base de données relationnelle pour simuler une base de données orientée objet. Ce programme définit des correspondances entre les schémas de la base de données et les classes du programme applicatif. On pourrait le désigner par là « comme une couche d'abstraction entre le monde objet et monde relationnel ».
Object–relational impedance mismatchObject–relational impedance mismatch creates difficulties going from data in relational data stores (relational database management system [“RDBMS”]) to usage in domain-driven object models. Object-orientation (OO) is the default method for business-centric design in programming languages. The problem lies in neither relational nor OO, but in the conceptual difficulty mapping between the two logic models. Both are logical models implementable differently on database servers, programming languages, design patterns, or other technologies.
User experience designUser experience design (UX design, UXD, UED, or XD) is the process of defining the experience a user would go through when interacting with a company, its services, and its products. Design decisions in UX design are often driven by research, data analysis, and test results rather than aesthetic preferences and opinions. Unlike user interface design, which focuses solely on the design of a computer interface, UX design encompasses all aspects of a user's perceived experience with a product or website, such as its usability, usefulness, desirability, brand perception, and overall performance.
Design numériquevignette|366x366px Incluant l’ensemble des pratiques utilisant des matières informatisées comme moyen et comme fin dans la conception, le design numérique (également appelé design d'interaction ou design interactif) définit les structures et comportements de systèmes interactifs. Apparaissant comme un nouveau champ issu de la révolution numérique, il réinvente la manière de façonner le design en mettant l’accent sur l’expérience de l’acteur et non l’objet en soi.
Entity–attribute–value modelAn entity–attribute–value model (EAV) is a data model optimized for the space-efficient storage of sparse—or ad-hoc—property or data values, intended for situations where runtime usage patterns are arbitrary, subject to user variation, or otherwise unforseeable using a fixed design. The use-case targets applications which offer a large or rich system of defined property types, which are in turn appropriate to a wide set of entities, but where typically only a small, specific selection of these are instantated (or persisted) for a given entity.
Database modelA database model is a type of data model that determines the logical structure of a database. It fundamentally determines in which manner data can be stored, organized and manipulated. The most popular example of a database model is the relational model, which uses a table-based format. Common logical data models for databases include: Hierarchical database model This is the oldest form of database model. It was developed by IBM for IMS (information Management System), and is a set of organized data in tree structure.
Interaction design patternInteraction design patterns are design patterns applied in the context human-computer interaction, describing common designs for graphical user interfaces. A design pattern is a formal way of documenting a solution to a common design problem. The idea was introduced by the architect Christopher Alexander for use in urban planning and building architecture and has been adapted for various other disciplines, including teaching and pedagogy, development organization and process, and software architecture and design.
Moteur de base de donnéesEn informatique, un moteur de base de données ou moteur de stockage (anglais database engine ou storage engine) est un composant logiciel qui contrôle, lit, enregistre et trie des informations dans une ou plusieurs bases de données. Le moteur de base de données est le composant central d'un système de gestion de base de données. C'est un composant essentiel des systèmes d'informations, ainsi que de nombreux logiciels qui manipulent des grandes quantités de données (voir Informatique de gestion).
Direct manipulation interfaceIn computer science, human–computer interaction, and interaction design, direct manipulation is an approach to interfaces which involves continuous representation of objects of interest together with rapid, reversible, and incremental actions and feedback. As opposed to other interaction styles, for example, the command language, the intention of direct manipulation is to allow a user to manipulate objects presented to them, using actions that correspond at least loosely to manipulation of physical objects.
