Abstract
The present disclosure discloses a second-degree friend query method. The method includes storing a first-degree friend of each account, querying for the first-degree friend after receiving a second-degree friend query command, and query the first-degree friend to obtain a second-degree friend. A storage module stores the first-degree friend relationships. The second-degree friend is obtained through a query according to the first-degree friend in real time. The present disclosure further discloses a second-degree friend query apparatus and system corresponding to the foregoing method and a storage medium. The system includes a processing server and a storage server. The storage server stores a first-degree friend for each account, and queries for and returns the first-degree friend at the request of the processing server. The processing server controls an entire query procedure, and obtains a second-degree friend after twice queries. Further, because the processing server can manage multiple storage servers, obtaining a friend relationship chain of multiple types in one query command is supported.
