Abstract: Embodiments of this application provide a middle frame, a battery cover, and an electronic device. The electronic device may include a mobile or fixed terminal with an edge frame or a housing, such as a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a walkie-talkie, a netbook, a POS machine, a personal digital assistant (PDA), an event data recorder, a wearable device, a virtual reality device, a wireless USB flash drive, a Bluetooth speaker/headset, or a vehicle-mounted device. Two types of materials: ceramics and plastic, are used to form a middle frame and a battery cover, thereby reducing a weight of the electronic device. This resolves a problem that is of a relatively large weight of an existing electronic device and that is caused when a pure ceramic middle frame and a pure ceramic battery cover are used in the electronic device.

Abstract: A data migration method and an apparatus are provided. The method is as follows: sending, by a first storage system, a location update request to a location server, where the location update request is used to indicate the location server to update location information of a first bucket from being located in a second storage system to being located in the first storage system (402); migrating data (405) in a first bucket from the second storage system; receiving a data access request, where the data access request is used to access the data (406) in the first bucket; and determining based on a type of the data access request and a migration status of the data, that the first storage system or the second storage system processes the data access request (407).
