If there is a fault in electronic system it can cause short circuit that may result in    overheating, fire or an explosion hence the systems in which system failure can lead to some physical damage falls in this category. Architectural Characteristics (Partially) Listed Architecture characteristics exist along a broad spectrum of the software system, ranging from low-level code characteristics, such as modularity, to sophisticated operational concerns, such as scalability and elasticity. monolithic architecture: This definition explains what a monolithic software architecture is and how it differs from a modular model such as a microservice architecture (MSA). We talked about concepts, we talked about architectures. Change ). The latest thinking in architecture descriptions recommends the concept of architectural design views. What is Expert System ? Systems architecture depends heavily on practices and techniques which were developed over thousands of years in many other fields, perhaps the most important being civil architecture. Each structure comprises software elements, relations among them, and properties of both elements and relations. There have been efforts to formalize languages to describe system architecture, collectively these are called architecture description languages (ADLs).[2][3]. Object communication is through a middleware system called an object request broker. Various organizations can define systems architecture in different ways, including: One can think of system architecture as a set of representations of an existing (or future) system. Two terms that are likely to be encountered frequently while reading about computer ­architecture are … we have given an introduction of architectural design in our previous blog, now lets see the key characteristics of system on basis of which we decide the architecture. Several types of systems architectures (underlain by the same fundamental principles[13]) have been identified as follows:[14]. iv), for example, the structural elements discipline the plan and general arrangement of the building and form an important part of the visual vocabulary.
