systems design is the process of defining the architecture, components, modules, interfaces, and data for a system to satisfy specified requirements. systems design could be seen as the application of systems theory to product development. there is some overlap with the disciplines of systems analysis, systems architecture and systems engineering. == overview == if the broader topic of product development "blends the perspective of marketing, design, and manufacturing into a single approach to product development," then design is the act of taking the marketing information and creating the design of the product to be manufactured. systems design is therefore the process of defining and developing systems to satisfy specified requirements of the user. until the 1990s systems design had a crucial and respected role in the data processing industry. in the 1990s standardization of hardware and software resulted in the ability to build modular systems. the increasing importance of software running on generic platforms has enhanced the discipline of software engineering. object-oriented analysis and design methods are becoming the most widely used methods for computer systems design. the uml has become the standard language in object-oriented analysis and design. it is widely used for modeling software systems and is increasingly used for high designing non-software systems and organizations. === architectural design=== the architectural design of a system emphasizes on the design of the systems architecture which describes the structure, behavior, and more views of that system. === logical design=== the logical design of a system pertains to an abstract representation of the data flows, inputs and outputs of the system. this is often conducted via modelling, using an over-abstract (and sometimes graphical) model of the actual system. in the context of systems design are included. logical design includes er diagrams i.e. entity relationship diagrams. ===physical design === the physical design relates to the actual input and output processes of the system. this is laid down in terms of how data is input into a system, how it is verified/authenticated, how it is processed, and how it is displayed as in physical design, the following requirements about the system are decided. # input requirement, # output requirements, # storage requirements, # processing requirements, # system control and backup or recovery. put another way, the
