摘要：本课题是基于Mainframe的开发，运用大型机技术进行后台数据管理，用JAVA WEB技术进行后台与界面交互，实现现代金融行业的贷款业务管理。由于本课题主要涉及展期管理，即用户贷款到期日结束之后，对未还清的贷款进行延期还款，其中涉及的利率、手续费、到期日等等,这些需额外审批后实行。因此本课题是基于已有贷款业务账户的数据处理，在开发过程中主要围绕3大方面进行：数据用和种方式存储、输入如何传输以及如何对数据有效分析。通过一系列的调查，决定将数据用VSAM文件进行存储，前台将数据以XML的形式传递至后台，写入VSAM文件，同时返回信息至前台显示结果。在调查之后发现用户存入的数据一部分可用于数据的分析，结合大数据的思想，用户借贷行为对社会的影响具有一定的意义，可以为银行或者借贷机构放贷时做出一定的预判。48938

Based on Mainframe Bank Loan Business System—

Design and Realization of Extend Loan and History Inquiry

Abstract: This topic is developed on the Mainframe system, which using Mainframe technology to operate the data and JAVA Web to communicate with background, its realize the loan business management in modern financial industry. Due to the topic is involved in the extend loan business, which those who loan is executed after the expiration date and the repayment of the loan not pay off. The extend loan involves the interest rate, the commission, the expiration date and so on, which need for additional approval after the implementation. The system is to process the data which is based on those who have the loan, so during the development process, it is focused on three points: How to storage data; How to transfer data and How to analysis data. After the investigation, the data can be storage by VSAM files, the data can be delivered to the Mainframe in the form of XML, write to the VSAM files and show result on the screen. It is found that part of data can be used for data analysis, combined with the idea of big data and user borrowing behavior of social influence has certain significance, for banks or lending institutions to lend to make certain anticipation.
