• Together, reliability, availability, serviceability, usability and installability, are referred to as RASUI. • Functionality, usability, reliability, performance and supportability are together referred to as FURPS in relation to software requirements. • Agility in working software is an aggregation of seven architecturally sensitive attributes: debuggability, extensibility, portability, scalability, securability, testability and understandability. • For databases reliability, availability, scalability and recoverability (RASR), is an important concept. • Atomicity, consistency, isolation (sometimes integrity), durability (ACID) is a transaction metric. • When dealing with safety-critical systems, the acronym reliability, availability, maintainability and safety (RAMS) is frequently used. • Dependability is an aggregate of availability, reliability, safety, integrity and maintainability. • Integrity depends on security and survivability. • Security is a composite of confidentiality, integrity and availability. Security and dependability are often treated together. ==See also==
