Abstract: Automated Index Management entails automated monitoring of query workload in a DBMS to determine a set of higher load queries to use to evaluate new potential indexes. Without the need of user approval or action, the potential indexes are automatically created, evaluated and tested, and then made available for system wide use for executing queries issued by end users. Indexes created by Automated Index Management are referred to herein as auto indexes.

Abstract: A terminal device obtains a first volume value in response to detecting that the terminal device establishes a communication connection to a first electronic device. The first volume value conforms to a use habit of a user when the user uses a second electronic device, and the second electronic device was previously connected to the terminal device. The terminal device sends a volume adjustment message to the first electronic device. The volume adjustment message carries first volume value information indicating to the first electronic device to adjust a playback volume to correspond to the first volume value.
