His research focuses on software architecture, design patterns and requirements engineering. Fault detection tactics, such as Ping-Echo, Heartbeat, Exception and Voting [16, 2, 4], are just measurement tactics to quantify the availability of the software architecture. The multiplicity of structures in an architecture lies at the heart of the concept. The functionality of both components and connectors are affected when tactics are applied to the software architecture [17]. Patterns are built from tactics; if a pattern is a crystal, a tactic is a molecule or an atom. Guard Server packages these individual heartbeats into The assumptive close is a sales tactic used to close a deal. He is currently serving on the editorial board of the International Journal of Pattern. A tactic may require another complementary tactic or exclude a conflicting tactic. One is the nature of the tactic, which indicates whether the tactic influences all components of the architecture or just a subset of them. to achieve a QA response. gically build an architecture. But at the same time it will have an impact on other QA or other aspects of the same QA ! Heart Love Signal.
