Design And Implementation Of Postal Self-Service Terminal Service Software

Since the current market of postal services is highly competitive, self-service equipment has been recognized by the society, and applied and developed in all sectors of the society. With the development of the Henan Post Office's business, self-service equipment is needed to conduct the repetitive operations instead of manual equipment so that the cost will be reduced and the corporate image of Henan Post Office will be improved.This article focuses on the design of self-service terminals and discusses why we should apply the self-service terminals to postal services based on the start of the demands. According to the existing business systems of Post Office, the article demonstrates how to design the architecture of self-service terminal system and gives the detail introduction of five representative transactions analysis models for zip code inquiry, newspaper subscription, public transportation card refill, air ticket order, and phone bill payment by using object-oriented analysis methods and theoretical ideas. Moreover, this article also shows the details of how to conduct the hardware interface code development based on the self-service terminal system, Tirst, this article shows the design and Implementation of Presentation layer, including the uses and developments of second-generation ID card reader and Radio Frequency Identification (RFID) card reader, For better introduction of those three types of hardware code development, the article starts with the overview of function analysis and working principle. Then it provides the detailed descriptions for the platform development, the use of API functions, and source codes. Second, this article shows the design and Implementation of Business Logic Layer.last. this article shows the design and Implementation of Component layer, including the design of Database operations Components,Tuxedo call Components,Multi-transaction control Components.At the end of this article, it discusses the scalability and maintenance issues of the system, explains the reasons leading to those problems and issues and points out the next step is to be done.
