摘要：With the development of Internet technology and cloud computing, cloud data management technology has emerged while the technology of traditional database management cannot meet the requirement. In this paper, we will compare the features and analyze the difference among the new cloud data management systems from data model, data partition schema, fault-tolerant mechanism of system, the load balancing mechanism of system and the model of data consistency and availability. And then we analyze and verified the system performance between the two open-source systems. Finally, research statuses of the cloud data management technology are analyzed and the key technologies in the research of cloud data management technology are summarized.
