| With the development of information and increasing of the web users, Electronic Commerce (E-Commerce) has been a hot topic among us. Cyber revolution gives an impact on the living mode of the public. More and more people, especially the youth, have been engaged in E-Business transactions. At the same time, it is surprising to most of us to find that some enterprises who are engaged in E-Business practices begin to come down after short term prosperities. The hardship Amazon confronted, which is the biggest online supermarket in the world, has given many investors a fierce hit.In Chapter 1, the author discusses the profound reasons for this phenomenon. As the majority of the cybershoppers, university students are a chief research target in our project. The author presents the background and motivation to exploit this project — E-Commerce System for Campus (In this paper, we can call it EC System for simplify). The EC System is an online shopping system, which was entrusted to exploit by E-Commerce institution of South West University Financial and Economics (SWUFE). This software consists of four modules which are 'Online Procurement System', 'Electronic Payment System', 'Inventory Management System' and 'Just_in_time Delivery System'. As one of the developers, the author is in charged of fulfilling the Delivery System. Due to care of the leader in E-Commerce instituteion and efforts of each one in our development, the EC System is in trial in E-Commerce institution of SWUFE now.In this thesis, the author discuss the key technologies the EC System use, analyze the designing course and also gives the practical examples for each key technology. The key technologies adopted in this software containe ADO.NET (A data access model), XML (Data exchanged technology standard) and Microsoft Message Queue Service mechanism. The thesis is chiefly a summary of the key technologies based on .NET platform, which are described in Chapter 2, and some practically design thoughts are proposed in Chapter 3. Therefore the two chapters were emphasized by the author.In Chapter 2, the author introduces each technologies mentioned above respecitivly. One example selected from the originality programme is quoated for each section. This chapter is totally divided into four sections:The first section in Chapter 2 introduces the frameworks of .NET proposed by Microsoft. A graph is made to illustrate functions of Common Language Runtime (CLR) and Base Class Library (BCL), which are the primary components of the .NET frameworks.The second section in Chapter 2 discusses constitutions of ADO.NET module. As an intermediary in three levels structure, ADO.NET objects are offered to help the customer's application access to the database. In the latter discussion in this section, the author refer to technology of Data Binding, which is usually combined with ADO.NET objects to fulfill data's picking up from data sources to Windows Forms. Finally, the author cites an example to illustrate how the technologies mentioned above combined with each other to realize the functions of our programme.As a new technology standard, XML (eXtensible Markup Language) makes it easier to interconnect different kinds of computer systems or different platform, thus allowing suppliers and customers to exchange orders and information more easily. The ADO.NET objects support the standard of XML completely, which makes this technology accessed to Database supervior to its seniorities. Therefore, in the beginning of this section, the author briefly states the advantages of XML compared with SGML (Standard Generalized Markup Language) and HTML (Hyper Text Markup Language), and the specifications of XML are presented at the same time. At the end of this part, the author takes the module of Replying to E-Mall for example to explain the process of packing into a XML file.The last section of Chapter 2 gives a detail description of Microsoft Message Queue technology (MSMQ). At the beginning, the author introduces the attributes a... |
