Abstract: According to embodiments, an electronic device comprises: a memory including a database file; and at least one processor connected to the memory. The at least one processor may: identify that the database file is damaged while a first application running on the electronic device accesses the database file; control a second application running on the electronic device to wait without accessing the database file until recovery of the damaged database file is completed; when the recovery of the damaged database file is completed, record recovery state information indicating that the database file has been recovered; and on the basis of the recovery state information, control the second application to access the recovered database file.

Abstract: An electronic device for providing a video call function, and a control method therefor are provided. The present electronic device comprises: a projection unit; a camera; a sensor for obtaining information about the distance to an external object; a memory for storing at least one instruction; and at least one processor which is connected to the projection unit, the camera, the sensor and the memory, and which is for controlling the electronic device. The at least one processor executes the at least one instruction so that, if a video call function is executed, a user is captured through the camera, and thus first user video is obtained. The at least one processor calculates a horizontal correction angle and a vertical correction angle on the basis of the first user video, the rotational angle of the camera, the projection angle of the projection unit, and a sensing value obtained through the sensor. The at least one processor obtains frontal video of the user on the basis of the first user video, the horizontal correction angle, and the vertical correction angle. The at least one processor controls the projection unit so that a video call screen including the obtained frontal video of the user is projected.

Abstract: Disclosed are an electronic device for recovering a database and an operation method thereof. The disclosed electronic device may comprise: nonvolatile first memory in which a database is stored; volatile second memory; and a processor operatively connected to the first memory and the second memory. The processor may: determine whether the database is damaged; when the database is determined to be damaged, perform a first integrity check of the database after initializing a DB cache in which at least a portion of the database is loaded in a user area of the second memory; when the first integrity check of the database fails, perform a second integrity check of the database after initializing an OS cache in which at least a portion of the database is loaded in a kernel area of the second memory; and when the first integrity check or the second integrity check of the database is successful, perform tasks on files in the database.

Abstract: An electronic device including a processor, a volatile first memory connected to the processor, and a non-volatile second memory connected to the processor is provided. A file manager configured to manage files stored in the second memory may be loaded from the second memory into a first memory area of the first memory and executed by the processor. A second application configured to access the files through a first application and the file manager may be loaded from the second memory into a second memory area of the first memory and executed by the processor. The first memory area may store instructions that may cause, when executed by the processor, the electronic device to, based at least on a request for directory data by the first application, read the directory data from the second memory through the file manager, return the directory data to the first application, and request the second application to store metadata describing files belonging to a directory corresponding to the directory data in the first memory area. The instructions may cause the electronic device to, based on a request for file data by the first application, read the file data from the second memory by using the metadata stored in the first memory and return the file data to the first application.
