数据迁移的一般原则

General Principle of Data Migration

在应用软件及数据库开发中经常要做数据迁移工作 ,数据迁移就是将数据从一种数据环境移入另一种数据环境中。进行彻底而精确的数据转换应遵循以下关键步骤 :识别源数据、确定数据集成转换的规则以及开发转换规则代码。介绍了数据迁移的一般步骤 ,并提出了从数据转换。

Data migration,that is migrating data from one data environment to another environment,is often did during application software and data base development.And the following key step should be followed as perform absoute and accurate data conversion:identification of source data,determination of data integrated conversion rule and development of conversion rule code.This paper introduces the general procedure of data migration,also presents migration tool evolution standard from angles of data conversion,selection of migration method and source data management.
