An information system architecture is a formal definition of the business processes and rules, systems structure, technical framework, and product technologies for a business or organizational information system.
An information system architecture usually consists of four layers:
- Business process architecture,
- Systems architecture,
- Technical architecture,
- Product delivery architecture.
The architecture of an information system encompasses the hardware and software used to deliver the solution to the final consumer of services.
The architecture is a description of the design and contents of a computerized system. If documented, the architecture may include information such as a detailed inventory of current hardware, software and networking capabilities; a description of long-range plans and priorities for future purchases, and a plan for upgrading and/or replacing dated equipment and software.
The architecture should document: What data is stored?, How does the system function?, Where are components located?, When do activities and events occur in the system?, and Why does the system exist?
