Asp Web Database Development

The rapid development of Web technology provides an efficient method for information exchange and share. The simple static page cannot meet the need of people, while the variable, flexible and interactive active page turns to be the direction of the development of new Web technology. The ASP fetched by Microsoft is an ideal tool for active pages compiling under the mode of browser/server. Besides of all of the functions of CGI(Common Gateway Interface) and ISAPI(Internet Service Application Program Interface), it also provides many other extraordinary advantages: it can process the clients' request more quickly, access database more conveniently and simply and provide supportable tools for almost all of the script languages. So that it has been accepted more easily. As a newly developed tool for Web application, ASP has shown strong power in Web database developing and become the main technology in dynamic net pages developing. It acts more and more efficiently in database application.The main points of the paper includes following:1 Introduces the architecture of Web database application system (B/S). By comparing with other technologies, the paper lists the advantages of ASP technology;2 Details the main technologies to in developing Web application database that includes ASP and ADO;3 As for the part of data display, the paper provides a new method for page diversion, which not only speeds up the visit of database but also reduce the use of resources.4 As for the part of data inquire, the paper advances blur inquire and long sentence inquire, so as to secure the sound result when received indefinite keywords;5 As for the part of database access, the paper provides an excelling method based on decision diagram ,which avails of the conception of entropy in Shannon's information theory and can reduce the time of data access so that huge database can be searched quickly, and decrease the cost of database design.6 Finally, the paper advances an example of products information search system based on Web.
