摘要
针对我军信息系统普遍存在"信息孤岛"和"数据烟囱"的现状,阐述构建统一高效、互联互通、安全可靠的军队数据资源体系,打通各军兵种信息系统,推动信息跨军兵种跨层级共享公用的重要意义,提出一种基于XML的数据迁移技术。该技术以XML文件作为数据交换中介,建立"源数据库-XML-目标数据库"的映射模型,生成源表与目标表之间的映射,根据实际需求进行字段格式转换、合并、拆分、计算等操作,实现数据在在新旧信息系统之间的无缝迁移,推动军队信息化建设。
According to the present status of ＂information isolated island＂ and ＂data stack＂ of our military information system, expounds the construction of a unified and efficient, secure and reliable military interoperability, data resource system, open every military information sys-tem, promotes the information sharing across the military cross level important public, proposes a data migration technology based on XML. The technology uses XML files as data exchange, establishes a mapping model of ＂Source Database-XML-Target Database＂, generates the mapping of source table and target table, field format conversion, merger, split, calculation and other operations according to the actual demand, achieves seamless data migration in between the old and new information system, promotes the construction of military in-formation.
