Software Architecture Description
Software architecture description is the set of practices for expressing, communicating and analysing software architectures (also called architectural rendering), and the result of applying such practices through a work product expressing a software architecture (ISO/IEC 42010, ISO/IEC/IEEE 42010). Architecture descriptions (ADs) are also sometimes referred to as ''architecture representations'', ''architecture specifications''Perry, D. E.; Wolf, A. L. (1992). "Foundations for the study of software architecture". ACM SIGSOFT Software Engineering Notes 17 (4): 40. doi:10.1145/141874.141884 or Software documentation#Architecture design documentation, ''software architecture documentation''. Concepts Architecture description defines the practices, techniques and types of representations used by software architects to record a software architecture. Architecture description is largely a modeling activity (Software architectural model). Architecture models can take various forms, in ...

Software Architecture
Software architecture is the set of structures needed to reason about a software system and the discipline of creating such structures and systems. Each structure comprises software elements, relations among them, and properties of both elements and relations. The ''architecture'' of a software system is a metaphor, analogous to the architecture of a building. It functions as the blueprints for the system and the development project, which project management can later use to extrapolate the tasks necessary to be executed by the teams and people involved. Software architecture is about making fundamental structural choices that are costly to change once implemented. Software architecture choices include specific structural options from possibilities in Software design, the design of the software. There are two fundamental laws in software architecture: # Everything is a trade-off # "Why is more important than how" "Architectural Kata" is a teamwork which can be used to produce an ...

Darwin is an architecture description language (ADL). It can be used in a software engineering context to describe the organisation of a piece of software in terms of components, their interfaces and the bindings between components.

Concern (computer Science)
In computer science, a concern is a particular set of information that has an effect on the code of a computer program. A concern can be as general as the details of database interaction or as specific as performing a primitive calculation, depending on the level of conversation between developers and the program being discussed. IBM uses the term ''concern space'' to describe the sectioning of conceptual information. Overview Usually the code can be separated into logical sections, each addressing separate concerns, and so it hides the need for a given section to know particular information addressed by a different section. This leads to a modular program. Edsger W. Dijkstra coined the term "separation of concerns" to describe the mentality behind this modularization, which allows the programmer to reduce the complexity of the system being designed. Two different concerns that intermingle in the same section of code are called " highly coupled". Sometimes the chosen module divis ...

Separation Of Concerns
In computer science, separation of concerns (sometimes abbreviated as SoC) is a design principle for separating a computer program into distinct sections. Each section addresses a separate '' concern'', a set of information that affects the code of a computer program. A concern can be as general as "the details of the hardware for an application", or as specific as "the name of which class to instantiate". A program that embodies SoC well is called a modular program. Modularity, and hence separation of concerns, is achieved by encapsulating information inside a section of code that has a well-defined interface. Encapsulation is a means of information hiding. Layered designs or packaging by feature in information systems are another embodiment of separation of concerns (e.g., presentation layer, business logic layer, data access layer, persistence layer). Separation of concerns results in more degrees of freedom for some aspect of the program's design, deployment, or usage. Comm ...

Architecture Description Language
Architecture 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. In the case of a so-called technical architecture, the architecture must be communicated to software developers; a functional architecture is communicated to various stakeholders and users. Some ADLs that have been developed are: Acme (developed by CMU), AADL (standardized by the SAE), C2 (developed by UCI), SBC-ADL (developed by National Sun Yat-Sen University), Darwin (developed by Imperial College London), and Wright (developed by CMU).

IEEE 1471
IEEE 1471 is a superseded IEEE standard for describing the architecture of a "software-intensive system", also known as software architecture. In 2011 it was superseded by ISO/IEC/IEEE 42010, ''Systems and software engineering — Architecture description''. Overview IEEE 1471 is the short name for a standard formally known as ANSI/IEEE 1471-2000, ''Recommended Practice for Architecture Description of Software-Intensive Systems.'' Within Institute of Electrical and Electronics Engineers (IEEE) parlance, this is a "recommended practice", the least normative of its standards. In 2007 this standard was adopted by ISO/IEC JTC1/SC7 as ISO/IEC 42010:2007, ''Systems and Software Engineering -- Recommended practice for architectural description of software-intensive systems''. It has long been recognized that "architecture" has a strong influence over the life cycle of a system. However, until relatively recently, hardware issues have tended to dominate architectural thinking, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

TOGAF
The Open Group Architecture Framework (TOGAF) is the most used framework for enterprise architecture as of 2020 that provides an approach for designing, planning, implementing, and governing an enterprise information technology architecture. TOGAF is a high-level approach to design. It is typically modeled at four levels: Business, Application, Data, and Technology. It relies heavily on modularization, standardization, and already existing, proven technologies and products. TOGAF began to be developed in 1995 by The Open Group, based on the United States Department of Defense's TAFIM and Capgemini's Integrated Architecture Framework (IAF). As of 2016, The Open Group claims that TOGAF is employed by 80% of Global 50 companies and 60% of Fortune 500 companies. Overview An architecture framework is a set of tools that can be used for developing a broad range of different architectures. It should: * describe a method for defining an information system in terms of a set of buil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

RM-ODP
Reference Model of Open Distributed Processing (RM-ODP) is a reference model in computer science, which provides a co-ordinating framework for the standardization of open distributed processing (ODP). It supports distribution, interworking, platform and technology independence, and portability, together with an enterprise architecture framework for the specification of ODP systems. RM-ODP, also named ''ITU-T Rec. X.901-X.904'' and ''ISO/IEC 10746'', is a joint effort by the International Organization for Standardization (ISO), the International Electrotechnical Commission (IEC) and the Telecommunication Standardization Sector (ITU-T). Overview The RM-ODP is a reference model based on precise concepts derived from current distributed processing developments and, as far as possible, on the use of formal description techniques for specification of the architecture. Many RM-ODP concepts, possibly under different names, have been around for a long time and have been rigorou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
