Data management method and apparatus using buffering

A data management apparatus comprising:

• a buffer managing device configured to allocate a buffers for an application based on request information associated with data requested by the application, wherein the buffers comprise a first buffer dedicated to storing first sensor data generated by a first sensor and a second buffer dedicated to storing second sensor data generated by a second sensor,
• wherein the buffer managing device is further configured to synchronize the first buffer and the second buffer such that a ratio based on an amount of the first sensor data stored in the first buffer and an amount of the second sensor data stored in the second buffer corresponds to a reference ratio requested by the application,
• wherein the buffer managing device is further configured to
• discard the first sensor data received in the first buffer until the amount of the second sensor data corresponding to the ratio is stored in the second buffer after the amount of the first sensor data corresponding to the ratio is stored in the first buffer, or
• store the first sensor data received in the first buffer in a spare buffer until the amount of the second sensor data corresponding to the ratio is stored in the second buffer after the amount of the first sensor data corresponding to the ratio is stored in the first buffer;
• a sensor managing device configured to store sensor data corresponding to the request information in the buffers;
• and
• a processing device configured to
• receive corresponding quantity information indicating a quantity of data to be transferred from each buffer of the buffers at a time point, and
• in response to an amount of the sensor data stored in the first or second buffer exceeding the corresponding quantity, transfer the sensor data stored in the corresponding first or second buffer to the application.
