Database reading and writing method and device

Abstract

Embodiments of the invention disclose a database reading-writing method and apparatus. A database is included in a terminal, wherein the database has at least one primary connection for executing a writing operation on the database and at least two non-primary connections for executing a reading operation on the database; the database reading-writing method comprises the steps that: the terminal obtains the reading operation on the database; if the reading operation is initiated by a first application, the reading operation is executed by the first non-primary connection; the first application is an application in the terminal, wherein the first non-primary connection is pre-set non-primary connection only used for executing the reading operation initiated by the first application; and at least two non-primary connections comprise at least one first non-primary connection. By adoption of the database reading-writing method and apparatus provided by the embodiments, the first non-primary connection is only used for executing the reading operation initiated by the first application, so that it is ensured that the executing efficiency of the reading operation initiated by the first application is not influenced by the reading operation of other applications.

Description

technical field [0001] The embodiments of the present invention relate to the field of terminals, and in particular, to a method and device for reading and writing a database. Background technique [0002] To facilitate the management of contact information, existing terminals usually use a contact database to store contact information. The application on the terminal can realize reading and writing of contact information through database operations such as read operation and write operation, so as to realize functions such as speed dialing and contact information backup. With the increasing diversification of terminal applications, more and more applications need to read and write contact information, so that the terminal needs to process more and more read and write operations. [0003] In order to improve the execution efficiency of database operations, the prior art generally adopts a write-ahead logging (WAL for short) mode to schedule read operations and write operati...
