The Study on Evaluation System and Method of Legacy System

Authors: Fuyang Peng, Chao Qi, Xiaoyan Su, Bo Deng

Abstract:

In the upgrade process of enterprise information systems, how to deal with and utilize those legacy systems affects the efficiency of construction and development of the new system. We propose an evaluation system, which comprehensively describes the capacity of legacy information systems in five aspects. Then we propose a practical legacy systems evaluation method. Base on the evaluation result, we can determine the current state of legacy system which was evaluated.

Keywords: Evaluation Method, Legacy Information Systems, Evaluation IndexSystem, Evaluation Level
