10. A method for controlling an electronic apparatus, the method comprising:
storing a plurality of pieces of data by a distributed data storing method in a memory of the electronic apparatus;
communicatively connecting to an external apparatus;
based on identifying that first data corresponding to the external apparatus among the plurality of pieces of data stored in the memory of the electronic apparatus replaced with second data, delete the first data and change a state of the second data to a locked state, and
transmitting the second data in the locked state to the external apparatus by a streaming method,
wherein, in the locked state, the second data cannot be changed in response to a data change command,
wherein the memory is a database accessible by a structured query language (SQL), and
wherein the method further comprises:
based on an instruction for identifying a change of the data and transmitting only the changed data to outside being undefined in the SQL, generating a separate control signal capable of directly accessing the memory without using the SQL and identify whether the plurality of pieces of data are changed based on the generated control signal.
