Extract literally translates as "enterprise extranet". Although it is behind the firewall like Intranet, it is not only for internal services like Intranet, nor completely open to the public like Internet. It is only selectively open to the outside world, or provides selective services to the public. Generally speaking, this kind of network is applied to the connection and information communication between enterprises (such as partners and customers), which is an extension of the enterprise intranet to the outside. In short, an extranet is a business to business intranet. Through the control of access duration, legitimate users are allowed to use the internal information resources of the enterprise to achieve the purpose of resource sharing between enterprises.
Extranet adopts Internet technology, which is cheap to use, and can connect the network to every corner of the world. This feature makes Extrant an important medium to realize e-commerce, especially in the cooperation between enterprises. For example, enterprises all want to reduce inventory, and it is better to produce without inventory. To achieve this goal, there are two prerequisites: one is to predict the supply situation of "going home" and whether it can be delivered in time. Because although I don't want to have inventory, I don't want to be short of supplies. If I know every link of the supply chain like production and transportation at home, I don't need to reserve a lot of production materials. The second is to predict the demand of "next home" (users), so as to arrange production and transportation in a targeted manner, to prevent the occurrence of goods shortage or supply shortage.
Before extranet, people often communicated information by phone or email. Information lag is a common thing. Although intranet technology provides a good bridge for internal communication, the communication between internal personnel of enterprises is not Website construction The main purpose of the application. For enterprises, the quality of the relationship with customers, suppliers and other working partners directly affects the profits and costs of enterprises. Taking procurement as an example, in the traditional intranet environment, the process of the company's procurement of raw materials is roughly that the company's internal engineers are responsible for publishing the specifications of each raw material on the company's internal network, and then the production personnel are responsible for notifying the procurement personnel to purchase, and any procurement problems are notified to the production personnel through the procurement personnel, and then the production personnel notify the engineers, In order to find solutions to problems, it often takes a lot of time and energy to go back and forth like this. What is more troublesome is that once a procurement procedure has problems, it is often necessary to contact all relevant personnel to solve the problem, which is time-consuming and laborious. However, through the application of extranet technology, the internal engineers of the enterprise can transmit the specifications of raw materials to the suppliers, or publish the specifications of raw materials on the intranet of the enterprise, and the suppliers can query the relevant procurement information by themselves. The suppliers can also directly feed back any procurement problems to the engineers, which speeds up the procurement and process of raw materials.
With the continuous expansion of the business scope and business volume of enterprises, the traditional internal intranet can no longer meet the needs of enterprises. Enterprises need to cooperate with other strategic manufacturers, or provide immediate customer service to expand the performance of enterprises and improve their work efficiency. Build an extranet and use the existing technology investment to reduce the construction cost; It is conducive to creating a virtual enterprise sharing information resources among upstream, middle and downstream companies, and providing better upstream and downstream relationships; Improve core operations, quickly respond to consumer needs, improve consumer satisfaction, improve communication efficiency, and save time costs; Reassign and integrate resources, reduce costs, improve work processes, reduce operating costs, and improve production efficiency and product quality.
