The Design And Implementation Of Banking Data File Exchange System

With the rapid development of the global IT technology,commercial banks started to step into the wave of information technology.They are not only improving the performance of business systems,but also strengthening the development of data warehouse,decision management and analysis support systems.In banks' daily data processing procedure,they would export its business transaction data into files,and then transfer them into data warehouse and multiple decision management and analysis support systems.As the amount of data increases year by year,data exchange between systems is getting more and more frequent.Therefore,banks have to face the challenge of how to transfer data files to data warehouse and decision management and analysis support systems efficiently.There appears the problems of data redundancy,uncontrolled concurrent transmission and uncontrolled dependency of data diversification,while banks are trying to transfer data files from traditional business systems to non-business systems directly.As a result,these problems hinder the pace of banking information construction.Accordingly,this paper has presented a detailed introduction and research on the requirement analysis,system design and implementation of the banking data file exchange system based on the features of it.The system provides a complete solution for banking file exchange,which has implemented the data file reception and storage,transmission,concurrent transmissions control management between servers and data file processing controlled by sequence of date dependencies.This paper has mainly completed the following researches:(1)The requirements analysis and design of banking data file exchange system.This paper analyzes the demand of data file exchange system,and proposes the concept of replacing traditional hybrid C/S architecture with cluster.According to the particular requirement of the data file exchange system,it completes the design of file storage of the cluster,the design of cluster architecture,and the design of job scheduling module.(2)The implementation of banking file exchange system.In this paper,the implementation of the cluster building up is achieved by the realization of cluster shared disk using GPFS,and it is based on the theory of design of cluster architecture and job scheduling.The implementation of unified data file processing management is achieved by encapsulating the data file transmissions into jobs.Job scheduling module is consist of job configuration module,job scheduling module,job execution module and job monitoring module.(3)The validation and testing of banking data file exchange system.Taking the data exchange system of banks for example,it proves that the file exchange system designed in this paper realized the functionalities of cleansing redundant data transfer,data file transmissionin sequential order according to data processing dependencies,and control of transmission concurrency of data downstream systems by the testing of system's each module.The results indicate that the banking data file exchange system is secure and efficient.
