Abstract

The invention discloses a data migration method and system. The method comprises the steps of reading target data in a source database; conducting first character transcoding on the target data with the first character coding format to obtain a middle character set, wherein the middle character set contains a first type of characters and a second type of characters; conducting second character transcoding on the first type of characters in the middle character set with the second character coding format, wherein the coding range of the second character coding format is different from that of the first character coding format; writing the second type of characters and the first type of characters subjected to second character transcoding into a target database.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data migration method and system. Background technique [0002] With the development of science and technology, the upgrade of application systems with various functions is getting faster and faster. When replacing a new system, it is only necessary to migrate the data in the old system to the new system. This process requires Introduce data transcoding technology to realize data conversion, so in the process of data transcoding, special characters such as invisible control characters cannot be compatible, etc., resulting in transcoding failure. [0003] For example, in host EBDIC encoding, Chinese fields start with OE and end with 0F, but when truncation occurs due to insufficient length, 0F is often missing, so when processing according to the UTF-8 encoding method, the last One field replaces the identification character, which is the 0x001A character, which represe...
