| Data audit and monitor system is a system that collect data from business supporting system and check these data to find the data inconsistency in order to prevent revenue leakage. Along with the development, there are many problems such as duplicated class and code, long method etc. These problems make the expandability and maintainability declined.In order to solve these problems, the following works have been done in the paper.First, refactoring and design the model of data audit and monitor system. After analyzing the data audit and monitor system, the model of main module, audit formula manage, audit task manage and audit result, has been refactoringed by using analysis patterns. And the strong points in expandability and maintainability have been descripted. Then based on the model, the design and code have been refactoringed by using design patterns.Second, design the data collection analysis pattern. Summarize the common analysis method of analysis patterns. And one data collection analysis pattern based on the heterogeneous data sources has been built. It provides foundation for the design of data collection module of the system.Through the refactoring of data audit and monitor system, the expandability, understandability and maintainability are increased in a certain extend. Meanwhile, the data collection analysis pattern provides a foundation for the software farther improvement. |
