The paper introduces the bookstore sales management sales management system,textbook management,module function implementation.Through the Unified Modeling Language (UML) modeling,the preparation of sales management,textbook management modules of the use cases,clearly shows the operation of the process modules; to draw the textbook management,sales management and use case diagram,sequence diagram create a system requirements model; use class diagrams to represent the object model to write code using VB.NET language,and ultimately the function of the module.
