For example, Ada's Package, Smalltalk-80 and C++'s class and data type can all belong to the component category. However, the operation set, procedure and function can not become a component even if they can be reused. Developers can develop new application systems by assembling existing components, so as to achieve the purpose of software reuse. Software component technology is the key factor of software reuse, and also the focus of software reuse technology research.
