The research on transaction system based on mainframe

In order to make all get the benefits of health care system, we need one platform which can hold very large scale data for all participation. And this platform is non-none other than IBM Z900 mainframe server system, DB2 Large-scale relational database and CICS transaction middleware. As the lowest bottom of all system dealing data, we store all concerned data through DB2 large-scale relational database which is at the mainframe. We also deal with data for program which concern many table data through the storage procedures of mainframe; of course, if the data is little, for example the small transaction-participation user medical clinic or medication card transactions, we use the CICS transaction middleware in the mainframe. The paper firstly introduces the background of system design, purpose and design goals. Following this, it mainly states system requirements, running environments, system structure, basic design concepts, functionality and system security precautions. The last gives the summary of this paper.
