The traditional database is designed for the structured data and the complex query. In the environment of the cloud, the scale of data is very large, the data is non-structured, the request of the data is dynamic, these characteristics raise new challenges for the data's storage and administration, in this context, the NoSQL database comes into being. The article compares and analyzes the general structure of the Cassandra, HBase, MongoDB, the data's distribution mechanism in the cluster, the mechanism of the fault tolerance, their support for the programming model and some relevant technologies, in order to provide some references for selecting or building the NoSQL database solution.
