The problems of and solutions need to be solved in "Online mobile phone sales system" are analyzed and studied. By comparing the development methods and techniques for structured and object-oriented design, the oriented object method is used to analyze and design "Online mobile phone sales system".In this paper, we carry out deeply needs analysis for "Online mobile phone sales system", including business needs, functional requirements and data demand analysis. In business requirement analysis, we use UML language to describe the system’s business process diagram, case diagram and class diagram, give out some relevant use case description. In functional requirements analysis, we analyze user roles, system use cases, overall system function package diagram in detail, and design the function module at the same time.
