5 shows the functional architecture that fulfills the passenger exchange service. The most straightforward way to convey the difference between technical architecture and enterprise architecture (EA) is by looking at the scope and focus of each. The functional design specifies WHAT a program should do, the technical design described how that functionality is to be implemented in code. With a technology landscape that evolves quickly, the roles of IT architects need to adapt as well. The role of the Functional Architect is a blend between Business Analyst, Product Manager, and Usability/UX Analyst. ). On many projects the FA is the Logical Solution owner who works along side the technical architect to design the functional behavior of a system. Many articles on functional programming, or FP, focus on low-level coding practices (such as avoiding side effects) and FP-specific patterns (such as the dreaded monad). For example, Fig. Functional architecture is described as “an architectural model that identifies system function and their interactions. The functional architecture includes the system functions and the data-flows between them. the structure of a Foo object) or just that the system returns a list of them and then put the details of the Foo object in the technical specification? In the functional specification, should I describe what precisely is returned (i.e. That’s why the distinction between the different types can sometimes become unclear. They don’t, however, touch on high-level design and architecture. Technical architect vs. solution architect vs. enterprise architect. As the name suggests, technical architects are more concerned with the technicalities and the specifics of a particular technology than with technology’s place in the enterprise. Yet FP principles can be applied at larger scales. It defines how the functions will operate together to perform the system mission(s). The design is for an API in case that makes any difference. Generally, more than one architecture can satisfy the requirements, Berton Manning for the Department of Defense (DoD). A sub-function of interest is F1.1 which operates the train and platform doors (i.e., opening, closing, warning, etc. The architecture is rooted on F1 that corresponds to the global control-command function. So the functional design may state that the program must attach a courtdate to a file when the user clicks a button with a specific name and position on screen.
