functional architecture vs logical architecture
November 13th, 2020

In fact it allows architects to model things both at a high and low levels, depending on the requirements, which makes it very important for the architecture process. It includes a functional architecture, a behavioral architecture, and a temporal architecture. From an abstraction level viewpoint, it represents a middle ground, sitting between the Conceptual and Physical architectures. The idea of decomposing a system’s speci cation along several ‘levels of abstrac-tion’ constitutes good practice in … Unlike these, however, logical architecture is quite broad in scope. A logical architecture should only be created after the system’s functions and requirements are clearly defined It does not define any particular system implementation, but rather the general guidelines so as to remain solution-neutral Model Based System Engineering Concepts: Functional & Logical Architecture 7 Design vs. Logical architecture describes how a solution works in terms of function and logical information. The logical architecture of a system is composed of a set of related technical concepts and principles that support the logical operation of the system. It defines how the functions will operate together to perform the system mission(s). Generally, more than one architecture can satisfy the requirements, Berton Manning for the Department of Defense (DoD). • Derived work products, such as tables and matrices, may be used to manage these relationships and ensure coverage and traceability. The presentation layer is what the client interacts with and what will be responsible for handling those interactions to the lower layers such as the business and data. Individual items identified in logical architecture may reside on common devices, physically. 5 shows the functional architecture that fulfills the passenger exchange service. Functional and Logical Structures: A Systems Engineering Approach 2011-01-0517 Mechatronics development continues to be a challenge for automotive OEM's and suppliers. This definition was developed for the SEBoK. Functional architecture is described as “an architectural model that identifies system function and their interactions. Discussion For instance, a diagram that leans strongly towards the con… ). It includes a functional architecture, a behavioral architecture, and a temporal architecture [2]. Architecture • Architecture selects the concept, decomposition and mapping of form to function • Architecture establishes the vector of design variables and operating parameters • Design selects of the values of the vector of parameters • This is what optimization is good for • Some work in “architecture… The architecture is rooted on F1 that corresponds to the global control-command function. A sub-function of interest is F1.1 which operates the train and platform doors (i.e., opening, closing, warning, etc. The primary difference between logical and physical architecture documentation is that, while logical architecture's concerns end with identifying functional elements of the system, physical architecture takes an additional step, specifying actual devices that those functional elements execute on. Functional architecture is described as “an architectural model that identifies system function and their interactions. It portrays the usage of the layered architecture with the usage of 3-layers. Process, Functional Architecture, Logical Architecture, Technical Architecture, Model-Driven Architecture, Adaptive Cruise Control 1 Introduction Motivation. It defines how the functions will operate together to perform the system mission(s). It defines how the functions will operate together to perform the system mission(s). (Created for SEBoK) Sources. For example, Fig. This means that these different … Really, the only limitations are the performance and capabilities of the physical device. • Generalization relationships may be used to inherit functions, requirements, and other relationships from each architecture to the next (functional to logical to physical). The functional architecture includes the system functions and the data-flows between them. Generally, more than one architecture can satisfy the requirements, Berton Manning for the Department of Defense (DoD). Generally, more than one architecture can satisfy the requirements. To further the confusion, the word "Architecture" tends to be associated with either “Requirements” or “Logical” whereas "Design" tends to be associated with “Physical.” This probably stems from the fact that we, the I/S community, are starting at Row 3 and in an absolute, Enterprise sense, don’t … The first layer shown is the presentation layer. A Functional Architecture is an architectural model that identifies system function and their interactions. ISO 5 defines logical architecture as: The logical architecture of a system is composed of a set of related technical concepts and principles that support the logical operation of the system. In computing|lang=en terms the difference between functional and logical is that functional is (computing) an object encapsulating a function pointer (or equivalent) while logical is (computing) non-physical or conceptual yet underpinned by something physical or actual. Functional Architecture 4.1 Logical View The logical view shown here is a model diagram of the system. functional decomposition. Logical Architecture vs Physical Architecture posted by John Spacey , May 30, 2017 Logical architecture is a structural design that gives as much detail as possible without constraining the architecture to a particular technology or environment.
