Software Engineering (2160701)

• Architectural design represents the structure of data and program components that are required to build a computer-based system
• It considers the architectural style that the system will take, the structure and properties of the components
• that constitute the system, and the interrelationships that occur among all architectural components of a system.
• Representations of software architecture are an enabler for communication between all parties (stakeholders) interested in the development of a computer-based system.
• The architecture highlights early design decisions that will have a reflective impact on all software engineering work that follows and, as important, on the ultimate success of the system as an operational entity.
• The software that is built for computer-based systems also exhibits one of many architectural styles.
• Each style describes a system category that encompasses
• A set of components (e.g., a database, computational modules) that perform a function required by a system.
• A set of connectors that enable “communication, coordination and cooperation” among components.
• Constraints that de?ne how components can be integrated to form the system.
• Semantic models that enable a designer to understand the overall properties of a system by analyzing the known properties of its constituent parts.
