摘要: 介绍分布式异构数据库的相关概念和特点,基于B/S模式设计分布式异构数据库迁移系统,将JDBC SQL数据类型作为各种异构数据库数据类型的中间模型,实现整体和部分迁移。说明了数据转换规则、数据迁移实现方法、转义处理、大型数据字段处理、迁移过程、断点续传。项目实例表明该系统具有较好的可行性和实用价值。

关键词: 分布式异构数据库, 数据库管理系统, 数据转换, 转义处理, 迁移过程

Abstract: This paper introduces the conception and features of Distributed Heterogeneous DataBase(DHDB), designs distributed heterogeneous database migration system based B/S model, which adopts JDBC SQL data type as the middle one of various data types, implements holistic and partial migration, and introduces type conversion, data migration method, transferred meaning and large data field management, migration process, as well as netants. The feasibility and practicality are proved in project cases.

Key words: Distributed Heterogeneous DataBase(DHDB), database management system, type conversion, transferred meaning management, migration process
