The Designing And Implementation Of The Data Gateway & Business Interface Of PISP Of Shaanxi

Postal integrated service platform (PISP) of Shaanxi Province has already begun to put into commercial operation, this is a typical on-line trade to deal with OLTP (On-Line Transaction Processing ) system.Operate in advance to withhold CHINA MOBILE and CHINA UNICOM telephone expenses system at present.The data gateway bears the different network of constructing, construct the form of the data differently , construct the conversion of the communication protocol differently, bridge graft work, it contact between getting leading interconnected system having at systematic host computer and outside this, it is a core of communication of ground floor of whole system. According to concrete business content, define various kinds of trade code and datum make the form, thus confirm the data processing model between data gateway and different business interface finally, this is the basic train of thought that gateway and business interface module are designed. Realize the course all on Unix platform entirely, develop and realize in C language. In order to describe better, it is necessary to build up and make the basic introduction with the data processing mode to the whole PISP system, imprison to network datum of module make the regulation , the module is controlled , the route is controlled, concrete business interface and redundant interface are defined and described in detail.
