Design And Implementation Of Online Banking Back-office Integration System (bis)

With the advent of economic globalization,banks need to develop more applications to meet clients' needs.However,isolated information systems have become a serious impediment for the information construction.EAI is a new way to solve the integration problem among complex IT environments.And with the usage of" Service-oriented Architecture(SOA),EAI can do this easier.Backend Integration System(BIS) plays an important part in Bank of China' snewplatform project.First,the paper describes the status and role of BIS in BOC' s New Platform. The system requirement and features are caught up too.In fact,we need to focus on three problems:How to shield the service,how to deploy the service dynamically and how to optimize efficiency.According to these problems,we come up with corresponding solutions which is based on Enterprise Service Bus.We create adapters to interact with the backend systems,create observer to monitor the service publish process and optimize efficiency in many ways.Beside this, we will discuss the architecture,working mechanism and technique selection of BIS.We will describe the implementation of request routing and service publishing modules in UML.
