云计算系统中Key-Value数据管理研究

Key-Value Data Management in Cloud Computing System

Key-Value数据库是应用于云环境下的典型云存储系统,基于key-value数据模型的研究对大数据管理或称云数据管理系统提出了新的需求与挑战,成为人们关注的热点。本文对key-value数据模型与数据读写方式作了简单介绍,引入了key-value索引机制,重点讨论了key-value查询操作,给出了关于多维点查询的通用算法。

Key-Value database is a typical cloud storage system applied within Cloud Computing environment. Based on re-searches on Key-Value data model, the new demands and challenges emerged for big data management, or Cloud Data Management be-came the new focal point of this area. This article started with a brief introduction on Key-Value data modeling and data input and out-put methods. Then with the combination of Key-Value index mechanism, the author emphasized on Key-Value indexing operation, pro-viding a general algorithm on Multidimensional Query.
