The Importance of Information in the Supply Chain Information is important because it provides the facts that supply chain managers use to make decisions. Without information, a manger will not know what customers want, how much inventory is in stock and when more products should be produced and shipped. In short, without information, a manager can only make decisions blindly. Managers must understand how information is gathered and analyzed. This is where information technology comes into play. Information technology serves as the eyes and ears of management in a supply chain, capturing and delivering the information necessary to make a good decision. For instance, an IT system at a personal computer manufacturer may help a manager analyze the information and recommend an action. The manager can use the remaining chips first, then look at demand forecast, and determine whether to order more chips. There are four reasons why timely and accurate information has become more important for effective logistics system design and operations. First, customers recognize information about order status, product availability, delivery schedule, and shipment tracking as necessary elements of total customer service. Then, managers realize that information can be used to reduce human resource requirements. What’s more, information increases flexibility with regard to how, when, and where resources may be used to gain strategic advantage. And finally, enhanced information transfer and exchange capability using the Internet is changing relationships between buyers and sellers and refining channel relationships.21.

Generally, data mining (sometimes called data or knowledge discovery) is the process of analyzing data from different perspectives and (1) it into useful information information that can be used to increase revenue, (2) costs, or both. Data mining software is one of a number of analytical tools for analyzing data. It (3) users to analyze data from many different dimensions or angles, categorize it, and summarize the relationships identified. Technically, data mining is the process of finding correlations or patterns among dozens of fields in large relational databases.Although data mining is a (4) new term, the technology is not. Companies have used powerful computers to sift through volumes of supermarket scanner data and analyze market research reports for years. However, continuous innovations in computer processing power, disk storage, and statistical software are dramatically increasing the accuracy of analysis while driving (5) the cost.A．organizingB．summarizingC．composingD．constituting

The entity-relationship（E-R）data model is based on a perception of a real world that consists of a clletion of basic objects,called（ ），and of relationships among these objects.An entity is a“thing”or"object"in the real world that is distinguishable from other objects.Entities are described in a database by asetof（ ）:A relationship isan association among several entities.The set of all entities of the same type and the set of all relationships of the ametype are termed an entity sct and relationship set,respectively.The overall logical structure（schema）of a database can be expressed graphically by an E-R diagram,which is built up from the fllowing components:（ ）represent entity set,（ ）represent atributes,ete.In addition to entities and relations,the E-R model represents certain（请作答此空）to which thecontents of a database must conform.The entity-relationship model is widely used in database design.A.thingsB.objectsC.conditionsD.constrains
