Embodiment Construction

[0040] figure 1 Shown is a flow chart of the data synchronization method between the memory database and the physical database of the present invention. The method includes: step 1, expressing the operation on the source database in the form of SQL operation, decomposing the SQL operation into SQL syntax and corresponding SQL parameters, registering the SQL syntax and SQL parameters for operating the source database, and combining the registered SQL syntax and SQL parameters are stored in the SQL management area for management; step 2, for data changes in the source database, generate logical logs in the form of SQL syntax combined with SQL parameters; step 3, according to the registered SQL syntax and SQL parameters, the Logical logs are redone at the destination database.

[0041]In step 3, each logical log is associated with an SQL syntax. When redoing the destination database, first search for the prepared SQL syntax through the SQL syntax registered in the management are...

Abstract

The invention relates to a data synchronization method between an memory database and a physical database. The method comprises the following steps: 1) representing the operation to the source database in the mode of SQL operation, decomposing the SQL operation to an SQL syntax and the corresponding SQL parameters, registering the SQL syntax and the SQL parameters of the operation source database, storing the registered SQL syntax and the SQL parameters in an SQL management region to manage; 2) for a data change of the source database, combining the SQL syntax with the SQL parameters to generate a logical log; and 3) regenerating the logical log of the step 2) in the target database according to the registered SQL syntax and the SQL parameters. The data synchronization method of the invention utilizes the prepare mechanism once and the execute mechanism many times to greatly increase the synchronization efficiency; the size of the logical log is reduced, the transmission loss of the system and the waste of the disk space are reduced; and the synchronization application and the corresponding SQL changes can be supported, and the updating and extending of the system can be supported.

Description

technical field [0001] The invention relates to a data processing method, in particular to a data synchronization method between an internal memory database and a physical database. Background technique [0002] Modern communication is increasingly dependent on computer technology. In the continuous development of telecom operators, various information systems have been established, including operating network systems, integrated camping systems, billing systems, office automation systems, customer service systems, large Customer management system, business analysis and decision-making system, etc. These systems have accumulated a large amount of valuable data. Through data mining, query analysis and online analysis of these data, market opportunities can be identified, market strategies can be formulated, and customers can be further improved. relation. However, these data materials are too large, and the number of records is often in the hundreds of millions. Taking China...
