The invention discloses an ETL (Extract Transform and Load) framework design method for safety monitoring business analysis, which comprises data extraction, data transformation and data loading. The data extraction is completed by the steps of obtaining source data from a plurality of heterogeneous data sources, affirming the data sources through utilizing an XML (Extensible Makeup Language) adapter and utilizing a timestamp to carry out incremental extraction; the data transformation process is a link for connecting the data extraction process and the data loading process, and data transformation is carried out in the process by utilizing two components, namely a data processing engine and an Redis storage engine; during data loading, data loading mainly includes two loading types, namely initial loading and incremental loading, the initial loading mainly utilizes an incremental loading engine to process, and the incremental loading utilizes a way of combining a batch loading engine and a real-time loading engine to process. According to the method, high unity of heterogeneous data is implemented for laying a foundation for the subsequent decision support work.
