Software Architectures for Real-time Systems

The solution to the complex nature of developing software is software engineering. Software engineering provides techniques for structured design, formal- and informal analysis, and software metrics. The part of software engineering concerned with highlevel design and analysis is called software architectures. The objective of architectural analysis is to verify quality requirements on software. It can be applied on any level in the design but it focuses on the structure of the software. While the architecture provides a high-level abstraction of the software, divergences between the designed system and the requirements can be detected early in the design phase. However, the structure of the software alone does not always provide enough information in order to analyze all requirements put upon a software system. Additional information about the software construction is provided by different architectural views. The number of views, and their contents varies depending on the system domain and the required quality properties to analyze.
