AI Technical Summary

Technical Problem

Traditional databases suffer from problems such as low efficiency in data organization and retrieval, insufficient data quality and preprocessing, and lack of comprehensive consideration of forecast model values, spatiotemporal continuity, and spatial correlation when processing meteorological and oceanographic data.

Method used

Employing a KEY-VALUE distributed in-memory database, and utilizing a three-level preprocessing mechanism and a multi-dimensional index structure, combined with EEMD transformation and GIS technology, we achieve data cleaning, classification detection, and schema reduction, thereby improving data quality and retrieval efficiency.

Benefits of technology

It improves the access efficiency and accuracy of meteorological and oceanographic databases, supports tens of thousands of concurrent queries, eliminates noisy data, standardizes data formats, and enhances the speed and accuracy of data retrieval.
