The invention provides a large data management system which adopts a distribution type framework. The system comprises a local data server and a principal data server, wherein the local data server provides a local clustered database which constitutes a high-availability cluster by means of two machines and a disk array; the principal data server provides cluster proxy service which is data access proxy service of the local clustered database. Preferably, the large data management system further comprises one or more clients which are suitable for determining whether the one or more clients have the authority to have access to a target data point by having access to the cluster proxy service, obtaining position information of the local clustered database where the target data point belongs to, and directly having access to the local clustered database corresponding to the position information. The large data management system solves the problem of super-large-scale data management capacity of a system by means of the distribution type high-availability cluster framework, and solves the problem of high-frequency data sampling and processing capacity by the adoption of a local real-time database.
