Abstract
For the transformation and upgrading of the data model for oil exploration and development, different structures of specialized databases, data sharing difficulties and other issues, the idea of data migration that builds data mapping to describe the differences between heterogeneous databases on account of database dictionaries is proposed. It forms a unified mapping analysis method and description for different structures to solve the problem of heterogeneous data models description and generic conversion. By parsing data mappings and compiling data files, the data migration and back-to-original conversion among large heterogeneous databases are realized. This system has been operating on the fields. It has done well at data migration, and achieved unified management and maintenance with exploration and development data.关键词
