Architecture en couchesIn software engineering, multitier architecture (often referred to as n-tier architecture) is a client–server architecture in which presentation, application processing and data management functions are physically separated. The most widespread use of multitier architecture is the three-tier architecture. N-tier application architecture provides a model by which developers can create flexible and reusable applications. By segregating an application into tiers, developers acquire the option of modifying or adding a specific tier, instead of reworking the entire application.
Architecture orientée événementsL'architecture orientée événements (de l'anglais event driven architecture, ou EDA) est une forme d'architecture de médiation qui est un modèle d'interaction applicative mettant en œuvre des services (composants logiciels) répondant à des sollicitations externes : avec une forte cohérence interne (par l'utilisation d'un format d'échange pivot, le plus souvent XML), et des couplages externes lâches (par l'utilisation d'événements) Par opposition à l'architecture orientée services (SOA) où un « fournisseur » r
Architecture description languageArchitecture description languages (ADLs) are used in several disciplines: system engineering, software engineering, and enterprise modelling and engineering. The system engineering community uses an architecture description language as a language and/or a conceptual model to describe and represent system architectures. The software engineering community uses an architecture description language as a computer language to create a description of a software architecture.
Fused gridThe fused grid is a street network pattern first proposed in 2002 and subsequently applied in Calgary, Alberta (2006) and Stratford, Ontario (2004). It represents a synthesis of two well known and extensively used network concepts: the "grid" and the "Radburn" pattern, derivatives of which are found in most city suburbs. Both concepts were conscious attempts to organize urban space for habitation. The grid was conceived and applied in the pre-automotive era of cities starting circa 2000 BC and prevailed until about 1900 AD.
