Problems solved by technology

[0003] In the above method, when the data in the OLTP system is converted to the OLAP system, not only the updated data from the previous conversion to the current conversion period are converted, but also the data that has not been updated from the previous conversion to the current conversion period Transformation is also performed, which will increase the data transformation time and thus reduce the data transformation efficiency

Abstract

The embodiment of the invention discloses a data conversion method and device. The method comprises the following steps of receiving a target operation instruction, wherein data information of data required to be operated is carried in the target operation instruction, and the target operation instruction is an insertion operation instruction or a non-insertion operation instruction; storing the data information of the data required to be operated in an on-line transaction processing system; and converting data corresponding to the data information stored in the on-line transaction processing system to an on-line analytical processing system during data conversion. With the implementation of the data conversion method disclosed by the embodiment of the invention, the data conversion efficiency can be improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data conversion method and device. Background technique [0002] In a row-column hybrid storage system integrated with an On Line Transaction Processing (OLTP) system and an On Line Analytical Processing (OLAP) system, OLAP queries are performed in the OLAP system. However, the data operation is carried out in the OLTP system. Therefore, in order to enable the OLAP query to query the updated data, it is necessary to convert the updated data in the OLTP system to the OLAP system. At present, one method of converting data in the OLTP system to the OLAP system is: converting all data in the OLTP system to the OLAP system. [0003] In the above method, when the data in the OLTP system is converted to the OLAP system, not only the updated data from the previous conversion to the current conversion period are converted, but also the data that has not been updated from the previous...
