Accurate measurement is a prerequisite for all engineering disciplines, and software engineering is not an exclusion. For decades seek engineers and researchers to express features of software with numbers in order to make easy software quality assessment. A large body of software quality metrics have been developed, and various tools exist to collect metrics from program representations. This large variety of tools allows a user to select the tool best suited, e.g., depending on its managing, tool support, cost.
