基于资源分类信息树的教育资源元数据分布式存储

Distributed Storage of Educational Resources Metadata Based on the Tree of Resource Classification

在教育资源大规模应用系统中，除了资源数据存储外，资源元数据信息的更新、获取也会成为系统的瓶颈。我们提出了一种利用资源分类信息树来辅助教育资源元数据分布式存储的策略，并就其各种操作进行了研究。该策略除拥有集中式存储的资源查全、查准特性外，还拥有灵活的扩展性，能应对大规模用户访问。

In large-scale application systems on educational resources， in addition to resource content， the updates and access of resource metadata will also become a system bottleneck. We propose a strategy for distributed storage of metadata of educational resources， and studied its various operations. This strategy is flexible， scalable and able to cope with large-scale user access.
