Document Summary
System architecture translates the logical design of an information system into a physical structure that includes hardware, software, network support, processing methods, and security. Objective is to establish a company-wide strategy for using it that includes a specific architecture, standards for data, processing, network, and user interface design. A main advantage is that it describes a specific hardware and software environment, also called a platform, which ensures connectivity and east integration of future systems. Erp systems to their suppliers and customers, using a concept called supply chain management (scm). Tco (total cost of ownership) includes tangible purchases, fees, and contracts called hard costs. However, additional soft costs of management, support, training, and downtime are just as important but more difficult to measure. A network is composed of individual nodes. A node represents a physical device, wired or wireless, that can send, receive, or manage network data.
