The invention provides a database model and a data processing method thereof. The database model comprises a user terminal, a gateway server, an application server and a data server, and the user terminal, the gateway server, the application server and the data server are in communication in sequence. The user terminal is used for obtaining data and sending the data to the gateway server; the gateway server is used for receiving the data, filtering the data, reserving target data, and sending the target data to the application server; the application server is used for sending the received target data to the data server which is in an idle state; the data server is used for splitting the received target data into multiple data blocks based on a preset rule, and attaching a data label to each data block to store the data blocks independently to form multiple blocky data carrying labels. The database model avoids the situations that a traditional database is easily cracked after being attacked, is low in work efficiency, and cannot solve problems in the data storage process under a large amount of data and the high concurrency condition of the data.
