Introduction to Software Engineering Overview 11th Chapter Summary

Software evolution is actually the maintenance of software.

In the software to reach the period of use, a variety of problems will still arise, these problems may be to correct the errors in the software, or to adapt to the new requirements, broadly divided into three types: corrective maintenance, adaptive maintenance, perfect maintenance.

Software maintenance is tantamount to the construction of a project, the need to spend a lot of things, the software construction process directly affect the maintenance of the software, in the process of maintenance of its general procedures and the process of building software is almost the same, so maintenance personnel must take up their responsibilities, the following several maintenance types of this chapter to do a detailed introduction.

Software re-engineering refers to the use of advanced software technology to 15 years ago or earlier software maintenance, because these software contains the core technology, we need to maintain. In this chapter for the software re-engineering to do a detailed introduction, roughly divided into several categories: Object selection, reverse engineering, document reconstruction, code refactoring, data reconstruction, forward engineering.
