基于 XML 的数据迁移技术在信息系统升级中的研究与实现

摘要

Aiming at the status quo of information system, we expound the importance of data migration in the process of information system upgrade, and propose an XML-based data migration technology.The technology uses XML as the data exchange medium, builds the mapping relationship between source database table and target database table, executes data migration according to practical demand, and realises information system upgrade.This technique has good scalability, openness and flexibility.%针对信息系统的现状，阐述数据迁移在信息系统升级过程中的重要性，提出一种基于XML的数据迁移技术。该技术采用XML作为数据交换的中介，建立源数据库表与目标数据库表的映射关系，根据实际需求进行数据迁移，实现信息系统的升级。该技术具有良好的扩展性、开放性和灵活性。
