The Design And Implementation Of The Development Platform For Internet Information Publish System

When the world has come into the information period, the fast development of internet and its widespread application in the whole world is changing the human life revolutionarily. Internet turns the traditional physics space into the electron space, and takes people into the internet world. Internet changes the traditional pattern of working and living, and with the powerful tool, the people not only can do some network work and entertainment, but also can do some network shopping with electric business.This article introduces the framework and workflow of "The Development Platform for Internet Information Publish System" which is part of "Integrate Platform for Developing Intelligent Agriculture Information System"(863 Program). During the course of design and implement, I summarize and inherit the theory research and the develop experience of the utility system and in the same time use the newest development technology for building a expediently using development platform.The Development Platform for Internet Information Publish System is a development tool for internet information publish. It integrates a B/S mode for facing information publishment into a development platform, hides the technology detail of the B/S application to developers, and shows a second development environment of friend-interface and simple application. Here developers need not do the page, manage the join among the codes, and even consider the security problem. All of these have been done by the development platform. Developers may only show the logic frame of publishing data, the data relation description and function description for users. It can create an Internet Information Publish System which has the function of menu-creation, building information browse interface, making and putting in orders and accessing local and long-distance database. Based the require analysis and design object of the platform, we design The Development Platform for Internet Information Publish System into the four layer system frame development platform of Windows NT. The bottom layer is operating system service layer, which is supported by the Windows NT operating system and IIS. This layer is made up of two parts: One is operating system component, the database accessing and main page translation (ASP page) of the platform both use the ADO database accessing component to access the database; the other is the service supported by the operating system and IIS, and the development platform based on Web which runs on IIS is a multiuser application program. The second layer is the development platform kernel layer which is above the operating system layer. It is the most important part of the platform and made up of database and page interpreter. The third layer is development platform tool layer. This layer faces the platform users, is an integrated development environment, and is made up of database accessing tool and webpage-creation tool. The top layer is the application system layer. This layer is made up of Internet Information Publish System based on Web which is created by The Development Platform for Internet Information Publish System, interacts with the last users and achieve the function of internet information publishment.
