【摘要】 为解决云计算中海量数据的存储管理问题,分析了关系数据模型和NoSQL数据模型各自的特点,提出了一种新的数据模型。该模型根据数据本身的特点将数据横向切分为一组实体的集合,不同的数据实体负责处理不同的数据应用,结合了关系数据模型的可用性与NoSQL数据模型的可扩展性。通过详细定义该模型的数据结构、约束条件以及数据操作,保证了数据模型的完整性。通过一个原型系统运行实例,验证了该模型的有效性,为云数据管理提供了可行的解决途径。更多还原

【Abstract】 To solve the problem of mass data storage and management in cloud computing,each characteristic of relational data model and NoSQL data model is analyzed,and a new data model is proposed.Data is transversely partitioned into a group collection of entities by this model according to the characteristics of the data itself,different data entities are responsible for their own applications,and this model is combined with the availability of the relational data model and the scalability of the NoSQL data model.After defining the data structure,data constraints and data operations of this model,the integrity of the data model is ensured.Finally,this model is validated by an application case of prototype system and the solutions are offered for cloud data management.更多还原
