Abstract

The invention discloses a method and device for data conversion as well as a method and device for data migration. The method for data conversion comprises the following steps: reading a data conversion rule which is described by adopting a domain specific language from a pre-generated configuration file, wherein the data conversion rule is used for appointing a conversion operation which indicates generating target data according to data to be converted; analyzing the data conversion rule and generating a data conversion algorithm corresponding to the data conversion rule; and reading the data to be converted and converting the data to be converted according to the data conversion algorithm. By adopting the method provided by the invention, the reuse of data conversion codes is realized, so that the workload of the developers is effectively decreased; and the domain specific language which is simple and easy to understand and low in learning cost is adopted to describe the data conversion rule, so that the common users which execute the data conversion operation can be qualified for configuring or modifying the data conversion rule in the configuration file.

Description

technical field [0001] This application relates to data processing technology, and specifically provides a method and device for data conversion. The present application also provides a method and device for data migration. Background technique [0002] With the development of the Internet, social data, online transaction records, social media and other data are increasing day by day. A large number of enterprises begin to have massive customer information. complex. These data are usually stored in various data sources, some are stored in traditional relational databases, such as: mySQL, oracle and other database systems; some are stored in NoSQL databases that have flourished in recent years, such as: HBase, Redis, etc. Database system; some are stored in the file system, for example: in the distributed file system HDFS (Hadoop Distributed File System, HDFS) of the distributed system cluster Hadoop. [0003] Due to the needs of system backup, upgrade, data exchange or da...
