中国石油已建统建信息系统与各专业分公司建设的信息系统之间，存在数据存储格式不相同、系统兼容性差、系统间的业务数据同步效率低等问题。针对该问题，通过设计“数据源端→中间服务器→地理信息系统目标端”的数据同步模式，提出了中国石油地理信息系统与其他统建系统、地区公司信息系统之间的数据同步方法。规范了各统建系统的动态数据接口，实现数据同步的历史可追溯性，为中国石油地理信息系统建设工作提供了可靠数据支撑，有效地提升跨系统数据同步的标准化程度及工作效率。%There exits some problems in the data synchronization process between the uni-fied system and the sub-branch system of CNPC, such as different data storage type, low system compatibility, and the low synchronization efficiency among different systems. Aimed at those problems, through the data synchronization mode’ s design from the data source to the middle server to the GIS target,the paper put up with a new data synchroniza-tion method among the CNPC’ S GIS system and other unified system or the sub-branch systems. And this method standardizes the dynamic data interface among different systems, which could reach the historic traceability of data synchronization. It could be expected to provide a solid foundation to the CNPC’ S GIS system data construction, and improve the standardization and efficiency of the trans-systems data synchronization effectively.
