Case Design for Software Engineering Training Course: Design and Implementation of Bank Securities Investment System

On the basis of software engineering courses, this paper combines open source service technology of IBM Z series mainframe and software engineering knowledge to complete the application development of bank securities investment system, which provides an experimental case of integrated software engineering technology for students. The technical platform of the system is based on the IBM Z series host, which adopts DB2 database system for data storage. For different users, the terminal operation mode and WEB browsing mode are used respectively. For the transaction process, the database information is accessed directly through the host CICS transaction program; For query and administration, the host database information is accessed through the Websphere server's CICS gateway or JDBC interface. The system demonstrates advantages of easy data operation, high efficiency and portability.
