Abstract

The invention provides a method for updating a memory database file which includes steps as follows: comparing the update-waited memory database file structure with a new edition database file structure for obtaining a difference information, confirming the update-waited database table and need not update database table in the update-waited memory database file according with the difference information; updating the update-waited database table according with the difference information, and updating the update-waited memory database file to a new edition memory database file according with updated database table and need not update database table. The invention also provides an updating device for the memory database file. The method and device provided by the invention can increase updating efficiency of the memory database table edition.

Description

technical field [0001] The invention relates to the communication field, in particular to an updating method and updating device for a memory database file. Background technique [0002] In recent years, the main applications in the field of telecommunications and finance have become data-intensive applications, in which database systems play an important role, data is the core of all systems, especially for communication systems, data access, storage and upgrades are more important important. [0003] In the communication system, the real-time requirements are very high. The traditional disk-based relational database system is far from meeting the above-mentioned high-performance and real-time data access requirements of the application. The memory database system can well meet the real-time requirements of various application systems. Data management needs. The so-called in-memory database refers to the establishment of in-memory data tables in the system memory, and the...
