Abstract:

National oil/gas database system is built to integrate and manage the multi-sources, heterogeneous national oil and natural gas data together those supplying for macroscopic decision of national resources utilization. The authors design an integration model for oil/gas data that has tow-level ETL tool, build the framework of system based on SOA using Web services as basic components. It uses Oracle 11g as the background spatial database, and uses C# as programming language to implement the system based on ArcGIS Engine and ArcGIS Server in secondary development method. This system can gather, integrate, publish and share the national oil/gas data. It combines the property data with spatial data to perform a number of spatial analyzing rapidly, such as buffer analysis. It provides the scientific data support for the history analysis and the future forecast of national oil/gas resources.

Key words: geographic information system（GIS）, service-oriented architecture（SOA）, oil/gas resources data, data integration, Web services
