DATABASE OPERATING METHOD AND FULLY ENCRYPTED DATABASE

Disclosed are a database operation method and a fully-encrypted database. The method is performed by a read node in a write-once-read-many database and comprises: receiving a read operation request from a user; determining that responding to the read operation request requires carrying out a write operation on a data key table; establishing a connection with a write node and forwarding the write operation; obtaining a data password table updated by the write node on the basis of the write operation; and on the basis of the updated data password table, generating a read operation response and sending same to the user. Thus, provided in the present invention is a write-once-read-many solution suitable for a fully-encrypted database, solving the problem of key information writing of a read node in a distributed database scene. When a user read request processed by the read node relates to writing key information, a connection with the write node can be achieved by utilizing remote SQL technology, such that the w
