基于EAP的异构数据迁移
摘要数据库是企业应用系统中的重要基础设施，随着计算机网络和数据库系统的迅速发展，软硬件的更新换代也是非常频繁，企业信息技术更新速度加快，应用系统经常需要更换平台以提供更好的性能并满足业务系统的需要，此时需要在系统间进行数据迁移。同时随着企业的规模的日益发展，造成企业应用系统中有异构性的存在，而其中异构数据库是尤为突出的一点，因而数据迁移的需求大增。异构数据库数据迁移是新型信息系统研制的重点之一。数据迁移是将数据从一个数据库系统移入另一个数据库系统当中，它不仅仅只是简单数据转移，还涉及到数据格式上的转换。在以往常用的方法的基础上，提出一种更有效的方法来实现数据迁移。由于XML具有较高的扩展性、灵活性和自定义等特性, 本文提出利用XML来处理、实现异构数据库系统之间的数据迁移问题。64533

Heterogeneous data migration Based on EAP
Abstract
Database is an important infrastructure of enterprise application system, with the rapid development of computer network and database system, software and hardware upgrades are very frequent, and enterprise information technology accelerates the speed of update.Under this way, the new application system often need to replace the old platform to provide better performance and meet the needs of the business system. At the same time, enterprise scale has been developed very quickly, which resulted in a heterogeneous enterprise application system. So heterogeneous database is particularly prominent, increased and data transfer is required. Heterogeneous data migration is one of the key application of information system development. Data migration is the data from a data environment into another data environment. It is not a simple data transfer, but also involves the data format conversion. Based on traditional methods, a method is proposed in this paper to achieve more effective data migration. XML has high scalability, flexibility and custom properties, so this paper processing, to achieve between the heterogeneous database's data transfer using XML.
