Electronic apparatus and information providing method using the same

A method operable by an electronic apparatus for providing information from a database while reducing access to the database, the method comprising:

• updating cache counter information of a cache database based on an update time interval, the update time interval determined based on counter information of a main database;
• receiving a counter information request;
• identifying the cache counter information of the cache database in response to the counter information request;
• and
• transmitting response information corresponding to the counter information request based on the cache counter information,
• wherein the update time interval is determined based on at least one of a counter value identified from the main database, a change speed of the counter value, or a residual value of the counter value.

An electronic apparatus for providing information from a database while reducing access to the database comprising:

• a communication device configured to receive a counter information request and transmit response information corresponding to the counter information request;
• a first database configured to store cache counter information updated based on an update time interval, the update time interval determined based on counter information;
• a second database configured to store counter information;
• and
• a controller configured to update the cache counter information of the first database in consideration of the update time interval determined based on the counter information, identify the cache counter information from the first database in response to the counter information request, and identify response information corresponding to the counter information request based on the cache counter information,
• wherein the update time interval is determined based on at least one of a counter value identified from the main database, a change speed of the counter value, or a residual value of the counter value.
