Application modernization is the refactoring , re-purposing or consolidation of legacy software programming to align it more closely with current business needs.Code refactoring is the process of improving code without making any functional changes. For a given method, that means the inputs and outputs stay the same but the code inside can be changed. The final product still behaves the same way to the users, but the code will have been cleaned up or upgraded. Brendan McCollam, engineering manager at ...Substitute Algorithm.
