AbsIrm-Due to the deregulation of the financial industry, bank branches now need to shift to a sales-oriented base, from an operation-oriented base. There are two types of office functions in a branch: front-office operations (i.e., counter work), and back-ollice operations. The latter functions require many office clerks and large amounts of time. To enable efficient baekollice operations, banks are now moving these operations to centralized business operation center. Forms received from customers at branches are scanned with image scanner, and the scanned data are then transferred electronically to the centralized business operation renter. There, the back-office functions can be performed more effectively.Branches handle a wide variety of forms, to which the centralized business operation center must correspond. Consequently, the challenge is to reduce the development cost of client applications used in this center.We propose new client application architecture based on B framework extending the Delegation Event Model and a component connection method using an event adapter. In this architecture, client applications can be developed by simply describing the screen configurations and lheir transitions in XML documents. By utilizing our architecture, we developed client applications for the central business operation center of a new bank branch system. Our experiments demonstrated B reduction in development cost of about 60%.
Due to the deregulation of financial industry, the branches in banking industry need to shift to the sales-oriented bases from the operation-oriented bases. For corresponding to this movement, new banking branch systems are being developed. It is the main characteristics of new systems that we bring the form operations that have traditionally been performed at each branch into the centralized operation center for the purpose of rationalization and efficiency of the form operations. The branches treat a wide variety of forms. The forms can be described by common items in many cases, but the items include the different business logic and each form has the different relation among the items. And there is a need to develop the client application by user oneself. Consequently the challenge is to arrange the development environment that is high reusable, easy customizable and user developable. We propose a client application architecture that has a loosely coupled component connection method, and allows developing the applications by only describing the screen configurations and their transitions in XML documents. By adopting our architecture, we developed client applications of the centralized operation center for the latest banking branch system. Our experiments demonstrate good performances.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
