Giving the educational Resource library life

Facing the increasing capacity of educational resources and the rapid development of information technology in education, the construction of campus network resources is confronted with many problems, such as "mixed resources, Liangfen and disturbing information too". The information data store occupies the leading position together with the network security, the fund reasonable allocation and so on in the education informationization, has become the campus network to the teacher, the student provides the Service foundation. Whether to have timely, accurate, comprehensive information storage, processing and extraction has become a measure of a campus network and research institutions have the development potential of an important indicator.

Construction of core resources of information development

With the further development of education informationization, the core position of teaching resources construction has been established. In recent years, information resources in the Internet have grown exponentially, and these resources have varied in content as well as in form. Its impact on education and infiltration makes the use of network education resources be paid attention to, and with the emergence of a new, student-centered, resource-centered teaching model. The characteristics of this web-based learning approach are: Resource based learning (resources-based Learning), which is an important way for students to learn by reading or finding lots of information.

The core of network education is the construction of network education resources, only with rich content, high-quality and practical Network Education resource database, all kinds of network education application system can give full play to the power of modern education technology and satisfy the students ' thirst for knowledge. Network education should provide a very rich learning resources for learners, including digital library, electronic reading room, online newspaper and various databases, multi-media electronic books and so on.

Why is the resource pool in distress?

Problem One: Resource classification is inflexible

This problem is a lot of universities and education Information Center in the beginning of the library has encountered, how to a large number of educational materials to classify the problem has been puzzling us. For example: According to the subject classification, may refer to the National Planning teaching material chapter to divide, but this kind of classification is advantageous in the school teaching, may not be advantageous to the student exploration self-study. According to grade classification, in the comprehensive knowledge expansion is not conducive to student inquiry learning; According to the "Integrable Ware Theory" classification, this requires the resource combination platform to browse, find, call, process, reorganize, expand and many other functions, but so far there is no one resource library backstage can integrate all these functions completely integrated.

Problem Two: Resource solidification

Now some of the resources of the courseware is often close to the content of textbooks and chapters of the order, and in today's economic development, the rapid updating of the era of information, textbooks update, revision of the situation always occurs. For example, the operating system in the information technology class is Windows XP, and the video teaching resource in the resource pool is Windows 98. It is not easy to modify and update these information resources, so that the life cycle of this solidified resource is shortened greatly.

In many repositories, besides providing a resource search tool, no other information integration tool is provided, and information retrieval technology is extremely backward. The resource database without processing analysis can only be regarded as data, these data are "dead", and the process of education and teaching is the process of students ' active learning, which needs the strong support of informatization and discipline integration, and is the process of information refining.

Problem three: The storage method is backward

In order to solve the problem of "curing", the actual change of school has carried out a lot of dynamic supplement, the teaching resource storehouse only "keep pace with the Times", and continuously perfect the effective resources, can guarantee the resource visit quantity. And the data volume of resource database grows far beyond people's estimate value, at the same time weaken the user's use efficiency, also appeared and the resource backup ability is insufficient, existence security hidden danger and so on negative factor.

Although many school administrators are aware that storage must "pave the way" for the resource pool to ask questions. But some of the departments in charge of education in the "school Pass", and did not add sufficient information on the application of funds, so that the resources stored in some schools are still blank. Some colleges and universities, although the administrator expanded the scope of backup, increased the recovery process, but did not put the tools or programs in the appropriate location, the data interpretation and archiving, such as the processing is still on paper.

Change in storage status

Information retrieval, refers to the disorderly and disorderly information in order to form a collection of information, and according to need from the information set to find out the specific information process, the full name should be information storage and inspection (information Storage and retrieval), The storage of information mainly refers to the selection of information in a certain range, description of its characteristics, processing so that the orderly formation of information sets, that is, the establishment of a database, which is the basis for the success of the search; Information retrieval refers to the use of certain methods and strategies to find the necessary information from the database, which is the purpose of retrieval, is the storage of reverse process. Storage and retrieval is a mutually reinforcing process. The early construction of the resource pool only to retrieve, despise the storage phenomenon is very common.

Many universities (or county Resource Center) Information centres face the problem: "When using direct-attached storage for storage management, when one system is low on storage capacity, there is no way to switch to another one to provide or add more disk space, while at the same time, some of the available storage capacity is underutilized These issues need to be deployed with a flexible infrastructure to support and respond quickly to growing teaching-assisted design resources. ”

When this problem arises, it is necessary to have a new concept to complete the fusion of storage and retrieval. Many foreign advanced digital libraries, not only to store a large number of electronic book materials, at the same time, the number of "T" video resources will be unlimited growth. The use of "old" storage technology is simply not able to complete data development and utilization, and then reposition storage technology as an intelligent management mode-"networked storage services."

Networked storage services are often defined as complex programs that automate the process of storing, classifying, and using information in a large degree. Software-based network Service automation ensures that these complex programs are executed effectively and reliably.

In addition, data can be collected automatically and can be accessed in real time, extending and terminating life in accordance with the plan. These theories and realistic conditions, all determine the role of storage services has changed, will become the core of our information construction.
