The invention discloses a multi-dimension data distribution method based on a data distribution base and belongs to the technical field of power grid data processing. The method includes the steps that firstly, the service logic is analyzed, the logic relation between the service function and tables in a database is analyzed, horizontal or vertical distribution is determined, the overall data partition rule is determined according to the service analysis result, the vertical distribution strategy is suitable for being adopted for a simple logic system, the horizontal distribution strategy is suitable for being adopted for a complex logic system, then multi-dimension mixed distribution is determined, and the distribution strategy in the data distribution base is combined to be the best mixed distribution by combination with the service logic; the finest granularity of data blocks distributed in a multi-dimension mode is determined through the highest common divisor rule by analyzing the storage space of cluster nodes; data distribution is achieved finally. The multi-dimension data distribution method based on the data distribution base can achieve high-performance data query and analysis, and meets the requirement of users for the real-time performance of big data processing.
