教育资源本体在关系数据库中的存储方法及其实现

Storage Method and Implementation of Education Resource Ontology in a Relational Database

随着数字化教育资源的成倍增加,准确查找教育资源变得越来越困难,本体与教育资源结合是解决问题的有效方案。为此提出了一种教育资源本体模型和构建教育资源本体方法,在结合本体和关系数据库特点的基础上,给出了基于关系数据库存储教育资源本体的六条原则,并设计了一种存储教育资源本体的关系模式。最后,通过在SQL Server2008中实现,进一步证明该方法在一定范围内的可行性和有效性。

With the increase of digital educational resources, it becomes more and more difficult to search educational resources accurately. The combination of ontology and education resources is an effective solution to these problems. Thus, this paper presents the model of educational resources ontology and the method to construct them. On the basis of combining the ontology and relational database, this paper presents six principles and relational schema of storing educa- tional resources ontology based on the relational database. Finally, this paper proves that the method is feasible and effec- tive in certain range through the implementation in SQL Server 2008.
