The Design Of Personalized Base91Plusg-in Network Sales

With the rapid development of Internet, the application of e-mail has been deeping constantly, and become the main contact way of people on the Internet gradually. As being the differences of the Internet network equipment, direct transmission of the eight binary data flow with Simple Mail Transfer Protocol can be unreliable sometimes, and it is needed to adopt an encoding method to convert the eight binary data flow into the printable ASCII characters. Now widely adopted encoding methods are Base64, of which the data extension ratio is133and the encoding efficiency is75%, while a new encoding methods—Base91encoding suggested by the professor Dake He’s, will make the data extension ratio decrease to123%, and the encoding efficiency increase to81.25%, thereby reducing the transmission data volume, reduce the time of channel taken up, attain the goal of increasing the transmission speeds and strengthening security and saving network bandwidth. The purpose of this paper is to promote this encoding method.In recent years, with the development of e-commerce, network marketing is commonly accepted, because it can reduce the manpower, material resources, and to provide more information. In addition, the network is not limited by region, and all over the world, thus it is vastly expanded the sales area. Because of these advantages, we finally adopt the method of network marketing to promote Base91encoding. Specific method is:1) developing plug-in components of Base91codec function as our product.2) developing a sales web site to sell the product. And the plug-in components of1) is based on the outlook2003, and has been developed by a precursor. While the work of this paper is mainly based on the PHP+MySQL technology, combine the characteristic of plug-in components, use the development tool Dreamweaver CS3to develop a personalize sales web site, and use DIV+CSS to layout and design pages.Analysising the research status at home and abroad, the paper first do detailed requirements analysis with the system, next according to the demand make an outline design and the detailed design step by step, finally give out the implementation procedure of the part function of the system and the main source code, and make the test, summarize and evaluation with the system.
