Abstract: The article introduces some important influences of Web technology on information system,
discusses the new characteristics of Web-based agricultural information system development method and
the key technologies.
Keywords: agriculture; information system; development method; Web
1 Introduction
Management information system (MIS) is an important embranchment of computer application field and
has been widely used in agriculture area, such as crop planting, seed breeding, livestock & fowl breeding,
soil fertilizer, irrigation, plant protection, farming mechanization, agricultural district, weather service,
agricultural science document and information management etc.. Agricultural Information System (AIS)
has been the core power of agriculture informationization in China. With the development of network
technology and the rapid spread of Internet，Web technology has developed rapidly and has been accepted
by lots of people for its using standard Browser via HTTP(Hyper Text Transfer Protocol) to display
multimedia information such as image, movies, sounds and so on, which leads great changes in architecture,
functionality, and development environment of traditional information system. More and more agricultural
information system have been developed using Web-based development method, which brings both
opportunities and challenges.
2 Influences that Web technology brings to information systems
Web technology brings information system some significant influences, as following:
2.1 Changes of information system architecture
Traditional information systems use Client/Server (C/S) mode (see chart 1). It is developed under
time-sharing and resource-sharing mode. This mode divides applications into two parts, which
accomplished by Client and Server cooperatively. The Client takes charge of communicating with user and
information collection, and sending out requests to Server. Server accomplishes the works that Client
cannot complete such as data manipulation or very complicated calculations. C/S mode can fully exert
server’s power, but at the same time it can also lead to trivialness of system exploitation and maintenance,
and results in network bottleneck incidentally.
