A reasoning framework for dependability in software architectures

摘要: The degree to which a software system possesses specified levels of quality attributes, such as performance and modifiability, often have more influence on the success failure those systems than functional requirements. One method improving level that product is reason about structure architecture in terms how well supports quality. This accomplished by reasoning through attribute scenarios while designing system. As society relies heavily systems, dependability becomes critical. In this study, framework for presented. Dependability multi-faceted encompasses reliability, availability, confidentiality, integrity, maintainability safety. makes complex other attributes. goal help architects build dependable using quantitative qualitative techniques architectures.
