Document Summary

Architecture design plans for how the system will be distributed across multiple computers and what hardware, operating system software, and application software will be used for each computer. Non-functional requirements developed early in the analysis phase play a key role in architecture design. Hardware and software specification: define what hardware and software are needed for the new system. The objective of architecture design is to determine how the software components of the information system will be assigned to the hardware devices of the system. Architectural components: major architectural components of any system are software and hardware, all software systems can be divided into four basic functions: Data storage: information systems need to store and retrieve data e. g. , data entities documented in erds. Data access logic: the processing required to access data stored e. g. database entities in sql. Application logic: the logic documented in the dfds, use cases, and functional requirements.
