Qujing City Teaching Of Primary And Secondary Education Data Resource Sharing Platform Integration

During the western audiovisual education reform in 2004,all elementary and middle schools in Qujing city have established some computer teaching environment,including the assistant teaching computer hardware equipments,the teaching software for the elementary and middle schools' education and the long-distance satellite signal receiving devices.Among them,every elementary school can use the long-distance satellite signal receiving system receives the data from the "modern country elementary and middle schools distance education resources net",and established the fixed compact disc broadcast classroom,the middle school has also established teaching computer network classrooms besides elementary schools'long-distance satellite signal receiving system and the fixed compact disc broadcast classrooms.All elementary and middle schools have successfully realized the network connection of fixed compact disc broadcast classroom,the long-distance satellite signal receiving system and the computer network classroom.Under the premise of basic hardware demanding,all the elementary and middle schools in Qujing city collected the data resources which were useful for their education through the "modern country elementary and middle schools distance education resources net" or the Internet.Under the existing condition,all the collected data resources basically deposited on their own servers,the data on the server will grow more and more as time goes by. Speaking of the existing server as the central structure in various middle schools,the constant growing data bring a kind of challenge to the server data storage space' s expansion:At the same time,the simultaneous visit on the same time from the massive students machines also gave the server's handling ability a higher request.Usually,the data collected in "modern country elementary and middle schools distance education resources net","TengTu Resources Storehouse" and the "Center Multimedia Education Star To Prepare a Lesson System " are frequently using in every middle schools' assistant education,all the middle school servers in Qujing city have these same data.they are dispersible on the various middle schools" servers,they server for various middle schools' education and do not share with each other.Used only by the schools" own teachers and students,it forms one and another information "isolated island".it also wastes various elementary and middle schools servers' isometric,limited data storage space.reduces the use efficiency of the investment funds.at the same time.looking the actual movement situation.if some middle school's server appears some breakdown which cannot be known in advance.the entire school education teaching data resources' usability has no safeguard in the same time.This article aims at the server data-carrier storage capacity expansion questions in all elementary and middle schools in Qujing city and the education and teaching data resources collection,storage,management and the server data resources usability questions,using the technology related with SAN,we conformed the education and teaching data resources in all elementary and middle schools in Qujing city,constructed a data resources sharing platform with easy expanding and high usability.It avoids the same data resources repetition on various elementary and middle schools servers in Qujing city. effectively saves the storage space on various elementary and middle schools servers.enhances the servers' server ability to student machines by the way of servers' clustering,enhances the responding speed of the system,enhances the usability of the education and teaching data resources using the SAN's fault-tolerant technology,this design has the certain reference value for the conformity and the optimization of the teaching data resources in every elementary and middle schools in Qujing city.
