而本文主要介紹了書店銷售管理系統(tǒng)中的銷售管理、購書管理等模塊功能的實(shí)現(xiàn).通過以統(tǒng)一建模語言（UML）進(jìn)行建模,編寫銷售管理、購書管理等功能模塊的用例,清晰的展現(xiàn)功能模塊的操作過程；以繪制銷售管理及購書管理的用例圖、時(shí)序圖來建立系統(tǒng)需求模型；用類圖來表示對(duì)象模型,用VB.NET語言來編寫代碼,最終實(shí)現(xiàn)其模塊的功能.
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.
