摘要
随着新技术出现和业务发展,企业运行多年的信息系统需要升级改造,需要将旧系统的数据迁移到新系统,保证系统切换后业务平稳过渡。数据迁移不是单纯的数据"搬运",而是按照全新的"图纸"进行数据"重构",不仅要对旧系统中的业务数据进行清洗,还要完成新老系统数据的映射关系和新业务要素的生成规则,并最终完成数据内容和格式的转换。在Eclipse开发平台上开发一款异构数据库数据迁移工具,利用XML为信息迁移平台,建立一种有效的"源数据库-XML-目标数据库"映射模型,实现异构数据库数据迁移,对信息系统数据迁移具有借鉴意义。
With the new technology and business development, corporate operation information system needs to be upgraded for many years, migrate data from old system to new system, guarantee system after switching the business smooth transition. Data migration is not a simple“move”, but shall be carried out data “refactoring” in accordance with the new “drawing”, not only to the old system of business data cleaning, data mapping and complete the new and old system and new business elements to generate rules, and finally complete the data content and format conversion. On the Eclipse development platform to develop a heterogeneous database data migration tools, use of XML for migration of information transfer platform, establish an effective “source database-XML-target database” mapping model, realize the heterogeneous database data migration, it has reference significance for information system data migration.
