Design And Implementation Of Debit Card Service System

To stabilize and develop the banking retail business of overseas branches, Bank of China Head Office proposed the project of "Issue Debit Card in Overseas Branches". The project target is to provide 7*24 non-stop global services to clients and deal with the problem of lack of branches aboard by issuing the debit card in overseas branches according to "MasterCard Maestro" standard.The main function of Debit Card Service System is as follows: to receive all kinds of transaction requests from debit card owner, to check the status of transaction account, to debit transaction amount from the account balance, to send the transaction results back to the original, to collect the annual management fee of debit card, and support the 7*24 non-stop global services.According to the method of software engineering and Model Falls, the article clearly analyzes the target of Debit Card Service System, the transaction process of debit card, 7*24 non-stop services solution and dataflow in detail. It also designs the hardware and software operating environment, architecture structure, database, communication, interfaces and module function. It proves its feasibility and correctness by coding and putting it in production. In fact, this system has achieved an excellent result after popularizing.According to software engineering, the article researches the implementation process of project and efficiently manages process and action, such as setting up project, planning project, analyzing requirement, general design, detail design, coding, testing, acceptance, popularization, project closure, monitoring and controlling etc. All of these can realize efficiency software engineering, produce the satisfied software to meet the final requirement and project goal.Finally, as project manager, the author summarizes his experience on software project management and points out the development direction of system.
