Abstract: An electronic device includes: a memory storing a database, a journal file for the database, and instructions; and a processor electrically connected with the memory. The instructions are configured to, when executed by the processor, cause the electronic device to: record a result of processing a transaction in the journal file through a thread of a process associated with the database; identify a size of the journal file through the thread; perform a lock for the journal file during a reference time through the thread, based on the identified size of the journal file through the thread; and transfer the result of processing the transaction to the database through the thread, based on a success of the lock for the journal file, the result of processing the transaction being recorded in the journal file.

Abstract: An electronic device for managing a database is provided. The electronic device includes a storage configured to store a database, a memory, and a processor operably connected to the storage and the memory. The memory stores instructions that, when executed, cause the processor to identify the state of a first file that is at least temporarily stored data stored in the database, the first file related to a first operation mode of the database, in response to identifying the first file in a first state that allows reading data included in a file, identify the state of a second file that stores information indicating a portion of the database to store information stored in the first file, perform transactions related to data stored in the database using the first file, based at least in part on the identified state of the second file, and in response to identifying the first file in a second state different from the first state, perform the transactions, based on a second operation mode different from the first operation mode.
