In the demand analysis stage, using activity diagram to describe the main business process, using the use case diagram to describe the core business requirements, and other non functional requirements. In the stage of design and analysis, the model is completed by the package diagram, class diagram, sequence diagram and activity diagram, and the model of the database is described by the attribute diagram and the diagram.In this paper, we design the basic functions of the stock trading system, including: Securities buying and selling, trading records, account funds and open positions, as well as the background of the management of accounts and other functions.
