So, this dissertation is to employ the principle of economics, management and information technology to analyze IS integration.This dissertation starts from the phenomenon of information redundancy and information isolated islands, which induct the issue of information system integration. After the analysis of enterprise application integration, the closed-loop control model is built to give further solution to efficient integration. As last, the dissertation ends with the conclusion and expectation. |
