Research On School News Information System For CZ College

News information system has changed the traditional conception of news spread, andprovides audience with new taste at vision, hearing and sense. Accordingly news informationsystem gradually becomes the preferred news medium for most people. CZ College is afamous vocational college which is developing quickly. However, the restraint of thetraditional news spread mode is accelerating the demand of school news information system.Based on above background, the paper studies CZ College school news information system,and tries to design the school news information system which fulfils the characteristic and thedemand of CZ College. Main contents are as follows.1. The existing news spread status of CZ College is analyzed, and its disadvantage ispointed out. Consequently the design principle of school news information system for CZCollege is confirmed.2. The function demand of school news information system for CZ College is put forward,and in succession, the performance demand of school news information system for CZCollege is confirmed.3. The system architecture of school news information system for CZ College is putforward is designed, and then the system architecture figure is drawn. Based on aboveanalysis, the function of school news information system for CZ College is designed, and thefunction tree is built. And furthermore, the system function mode is set up with IDEF0technique. According to the demand, the database of school news information system for CZCollege is designed, and the database design includes the database concept design, databaselogic design and database physical design.4. The system visitation quantity is discussed which is the important problem for schoolnews information system. The amounts of all kinds of students of CZ College are forecastedwith exponential smoothing method and weighted moving average method. Then the averagesystem visitation quantity school news information system for CZ College is forecasted withcausal forecasting method. And accordingly the system visitation quantity monthly of schoolnews information system for CZ College is forecasted with seasonal forecasting method.5. The news evaluation is also discussed. Batch news evaluation and whole newsevaluation are respectively analyzed. The news evaluation indexes are set up, and the newsevaluation methods are put forward. Both news spreader evaluation and news receiverevaluation are integrated into news evaluation. News spreader evaluates the news according to activation value, information value, education value, entertainment value and society value.News receiver evaluates news according to news visitation quantity and news responsequantity. Finally the news instance is evaluated to illustrate the news evaluation methods.The study has finished some especial jobs at the system function design, database design,transaction logic design and other aspect of school news information system for CZ College.The school news information system will directly be applied to CZ College. Consequently thesystem will break the situation about absence of school news information system in CZCollege, and will upgrade the information level and news media level for CZ College.
