The invention discloses a 
multidimensional model based oil and gas resource data key 
system implementation method and 
system. According to the 
multidimensional model based oil and gas resource data key 
system implementation system, sorting, cleaning, classification and systematization are performed on 
source data of oil and gas resources, cleaning, transformation and integration are performed based on an ETL (Extract-Transform-Load) framework, the 
source data are loaded into a 
data warehouse or a market to form a core 
database, and the 
data processing efficiency is improved and 
data mining is performed through establishment of a 
multidimensional model. According to the multidimensional model based oil and gas resource data key system implementation method, different latitudes of the data can be flexibly combined, the custom analysis on core data such as the oil price, the yield, reserves, the quantity of the resources, import and export and the mining right is achieved, integrated management and visual display of statements, 
graphics, texts and maps are supported, interfaces and function modules of the system are based on a configuration scheme, and accordingly the configuration is flexible, the extension can be performed, the use is easy, the display form of the data is enriched, and the retrieval efficiency is improved.
