The Measurement of Software Rruse Basing Homomorphism

Inheritance of OO or component is usually applied in the way of traditional software reuse, and the degree of reuse cannot be known beforehand. So the measurement of software reuse can only be gotten after program is finished. This way is so inconvenient in practically application. In order to solve these problems, we study the homomorphic reuse of problem through the reuse basing homomorphism in this paper, and address the concept in degree of homomorphic reuse. By calculation of the degree of homomorphic reuse, the reuse measurement of the known program can be gotten before writing program, We can apply software reuse purposefully and selectively. Through the way, the systemic and wide use of software reuse is possible in writing program.
