Research on Multi-source Heterogeneous Ocean Data Integration System

The multi-source heterogeneous nature of marine environmental element data makes it impossible to achieve unified management and sharing, it is easy to cause problems of information island, technology island, and resource island, the economic and social values contained in the data cannot be fully utilized. In order to manage data more scientifically and efficiently, this paper designs a multi-source heterogeneous marine data integration system based on ETL architecture to achieve the goal of information exchange and resource sharing. In this paper, the resampling method is used to perform interpolation experiments. The grid data of the same latitude and longitude are selected for comparison in the time dimension. The experimental results show that the data provided by the system after data integration is relatively reliable, has achieved the construction goal of the multi-source heterogeneous marine data integration system, and has improved the data island phenomenon to a certain extent.
