What are the main ways of network application

Enterprise Information Network refers to the computer network dedicated to the internal information management of enterprises, it is generally dedicated to an enterprise, covering the various departments of enterprise production and management, providing the sharing of hardware, software and information resources throughout the enterprise.

According to the geographical distribution of enterprise management, enterprise Information Network can be either local area network or WAN, which can be used to lay out the media in the near range, and can also use public communication medium in the remote area, which is the important technical basis of enterprise management Information System.

In the Enterprise Information Network, the information management function of the business function is provided by the microcomputer as the network workstation, carries on the collection and processing of the daily business data, while the control center and the data sharing and management center of the network are realized by the network server or a powerful central host, for the branch offices distributed in the wide area, Offices, warehouses and other remote business units, according to the size of their business management and information processing characteristics, through the remote simulation terminal, network remote workstation or LAN long-distance interconnection to achieve mutual interconnection.

At present, the Enterprise Information Network has become the modern enterprise's important characteristic and realizes the effective Management Foundation, through the Enterprise Information Network, the enterprise may get rid of the inconvenience which the geographical position brings, carries on the timely, the unified management and the control to the widespread business, and realizes the enterprise-wide information sharing, Thus greatly enhances the enterprise in the globalized market the competitive ability.

Enterprise Information Network Example:

Computer network application--online things processing

Online transaction processing refers to the use of computer network, will be distributed in different geographical location of the business processing computer equipment or network and Business Management Center network connectivity, so that on any network node can be unified, real-time business processing activities or customer service.

Online transaction processing is widely used in finance, securities, futures and information service systems.

For example, the banking network of the financial system, through dial-up lines, dedicated lines, packet-switched networks and satellite communications networks covering the entire country and even the global, can achieve a large range of savings business through the deposit of withdrawal, in any one branch, branch of the nationwide liquidation and transfer of funds.

On the ATM network, users can obtain withdrawals, deposits and transfers from any ATM machine with a credit card.

In futures, securities trading online, all the member companies all over the country can make quotations, transactions, delivery, settlement and information inquiries through computers. In addition, the Civil aviation booking system is also a typical online transaction processing, in the country and even around the world to provide air tickets booking and ticketing services.

Computer Network Application--pos system

POS (Point of Sales) system is a business enterprise management information system based on computer network, which is a network of commercial registers and computer systems used for collecting and clearing in the counter, and provides real-time integrated information management and service for commodity transactions.

The commercial cash register itself is a kind of special-purpose computer, which has the functions of commodity information storage, commodity transaction processing and sales document printing, which can be used separately at commercial point of sale, or can be run as network workstation on the network.

The POS system connects all the cash registers of the mall with the information system host of the shopping mall, realizes the overall management of the market's entering, selling and depositing business, and can communicate with the bank's business network, and support the customer to settle the direct with the credit card.

Computer network Application--e-mail system

e-mail system is a kind of non-real-time communication system, which is based on the functions of data processing, storage and transmission of computer and computer network.

The basic principle of e-mail is: In the computer network host or server's memory for each mail user to establish an electronic mailbox (open up a dedicated storage area), and give a mailbox address, the mail sender can in the computer network workstation (such as PC), the Mail editor processing, And by the recipient's email address to indicate the mail destination; After the message is sent, the network communication device determines the optimal transmission path according to the destination address of the message, transfers the message to the host or server of the recipient, and stores it in the corresponding mailbox; the recipient can open his or her own mailbox through the network workstation at any time, Review the messages that you receive.

Advanced e-mail systems can provide "text box", "voice mail," Graphic image box "and other types of electronic postage functions, supporting data, text, voice, graphics, images and other multimedia messages, and can be a variety of programs, data files as attachments to e-mail messages sent. Therefore, many e-mail based network applications can be constructed.

At present, worldwide e-mail services are provided through a data communication network based on packet switching technology. With the improvement of network capability and the increase of network users, e-mail will gradually replace the traditional mail delivery system and become a widely used non real-time communication means.

Computer network application--Electronic data interchange system

The Electronic Data Interchange System (Electronic data interchange, referred to as EDI) is a system based on the e-mail system, which is specialized in the business management of trade, transportation, finance, customs, insurance and other related business information, In the internationally recognized standard format, through the computer network, in accordance with the agreement between the trading partners of the computer system fast transfer, complete the trade-centric business process.

EDI is sometimes referred to as paperless trading, since EDI can replace a large number of written trade documents and documents passed between traders in the past.

The application of EDI is based on the trade and economic business documents, document format standards and network communication protocol standards. Business information is EDI processing objects, such as orders, invoices, declarations, import and export licenses, insurance policies and shipping orders, such as standardized business documents, their format standard is very important, the standard determines the EDI information can be different trading partners of the computer system to identify and deal with. EDI's information format standards are generally based on the EDIFACT standards developed and recommended by the United Nations Economic Commission for Europe.

EDI is applicable to industries and departments that need to deal with and exchange large amounts of documents, whose business characteristics are frequent transactions, periodic operations, large capacity data transmission and data processing. EDI in Europe, North America, Oceania and Asia-Pacific region in Japan, Korea and Singapore and other countries are widely used, some countries have clearly stipulated that the use of EDI Technology import license, customs declaration and other trade documents to give priority approval and processing, and the delay in the processing of written documents. The rapid development of international EDI application has promoted the implementation of EDI work in China, and in 1991 China has set up the "Chinese Promotion EDI application Coordination Group", and joined the relevant international organizations, EDI application and development into the National Science and Technology Project, the Economic and Trade Commission, customs, Banks, Transportation and other systems as well as some provinces and cities have carried out different degrees of research and application work, and some have begun a trial run. From the current level of scientific and technological development, the realization of EDI is not a technical issue, but a management problem.
