【正文】 processor server resources would lead to operate at a slower pace. Moreover, the use of CGI Web application development support is a more difficult process of the database, linking state management is very important. Without state management, then every browser request, require the establishment of a link with the release process less efficient. CGI does not provide state management functions, and must use a specific database server dedicated to SQL language manual preparation of the database interface, and its portability is well. 2) JDBC Discuss the introduction of a vibrant and dynamic Web. Inter users can download Java from Web service objects to the small local browser, operating procedures. These procedures like downloading small local procedures, can independently visit local servers and other resources, and the initial database programming language did not visit functional, with applications in depth, providing a database for Java visit function has been getting higher and higher. To prevent the emergence of Java in the database visits different expansion Java Soft JDBC pany developed as a database programming language is the first visit API, JDBC standards, support Java database API, which makes it easier to discuss procedures and database connections. JDBC and ODBC functions in the same development staff to provide a unified database visit interfaces. At present, many manufacturers have JDBC support, including Borland, Oracle and Sybase, and other panies. Most of the current popular database systems are introduced its own JDBCdriven process. 3) JSP JSP Java Server Pages is short Sun is the Java language development on the basis of dynamic web technology. Servlet and JSP with JavaBean technology, Logic and the website design and website shows separation, and support for reusable ponentbased design, Webbased application development bees quick and simple. JSP to good portability and platform independent, powerful interactive capabilities, and data processing capability quickly swept the world. on the Inter almost everywhere can see it in a hurry, and the website language is a dynamic future development trends. JSP technology for the creation of dynamically generated content showed the Web page provides a simple and rapid method. JSP is designed to make Webbased structural applications easier and faster. These applications can with a variety of Web server, application server, browser and development tools work together. JSP standard Web servers, application servers, transaction system and the development tool vendors extensive cooperation between the results. In traditional web HTML document (*htm. html) to add Java fragment (Script let) and JSP tags (tag) , constitutes a JSP website (*.jsp). Web server in the face visit the website at the request of JSP, the first implementation of the procedures footage The results would then be implemented in HTML format back to the customer. Procedures fragment can operate databases, and the reorientation website , etc., This dynamic site is to build the necessary functions. All operating procedures in the implementation of server, work uploads given client is only the result, on the client browser requests a minimum, can be achieved without plugin, no ActiveX, no Java Applet, even without Frame. JSP technology is based on Java open process products so it can support the widely different providers with the tools, Web servers and application services, This enables the user to choose the best method of developing and select the most responsive to their application development tool kits, effective protection of the user code, and staff training on the investment, so they have an even broader prospects for development. 4) ASP ASP is Microsoft Corporation in November 1996 launched Web application development technology. Microsoft in the relevant files, ASP is described as: a server script environment, and can generate dynamic operation. The world, highperformance Web service device applications. ASP is a Windows dynamic site recognized the best tool. It is fully integrated with ado to provide a powerful database visitation function to bee a major online database management tools.
