The Design And Implementation Of A Enterprise Online Bank System

The enterprise online bank of Banco Nacional Ultramarino is a management system used to enhance the core competitiveness of the banks,facing the pressure of the financial market in the Macao Special Administrative Region.The system is based on the actual status of regional cities commercial banks and developed by advanced design methods and technologies.In this paper,the system development background has been discussed,as well as current research status of online bank system.Then problems to be solved have been clarified by describing the two aspects of system.During the course of system design,the work begin with architecture design.The function architecture,technology architecture,security archiecture and commounition architecture are bulit at first.The the system use case analysis method,the interface design strategy and the design procedure of database structure have been discussed in detail.At last,several important problems encountered during the implementation have been analyzed.Effective solutinos to those problems encountered during the procedure of requirement analysis,design and implementation have been put forward in this article. All those supply powerful examples for the enterperise online bank system developmemt.The key problems solved in this paper are as follows:First,Improved waterfall model solved the problem that tradition waterfall model can not retrospect,and avoided the inconsistent with the needs of the users after the sofware completion.Rapid prototyping,a system development method based on computer,is proposed recent years.In this paper,rapid prototyping is used with waterfall model to complete the system analysis,desing and implement.Then the user requirement can be fully understand and the system can be optimized step by step.Second,management information system based web is easier to be attacked and destroyed,so the system security architecture is buit when the system architectur was designed except the hardware proteciton.The authorization system is developed to authenticat user's identity by using the Role-Based Access Control model.Third,in so many solutinos of builiding B/S structure,J2EE and SPING becomes the most favorable one because of the excellence it has been putted up when develop Web application.According to the user's requirement and the characteristic of this system,we use the J2EE platform.The representation layer architecture Struts and persistence layer architecture Hibernate is also used to reduce the cost and improer the maintenance and expansibility.Fourth,in this paper the database structure design,one of the key questions in the MIS development,begin with the conception model design,and then the object-oriented model,at last the physical modle is built.This kind of method makse the database design more reasonable.Fifth,effective methods are put forward to sovle the problems often encountered in the implementation of the enterperise online bank system.The enterperise online bank system has been trial run in Banco Nacional Ultramarino and achieved certain results.
