示例用法

olap_model = OLAPModel() olap_model.add_sales_data(SalesData("Product A", "Region 1", "2023-01-01", 100)) olap_model.add_sales_data(SalesData("Product B", "Region 2", "2023-01-02", 150)) olap_model.add_sales_data(SalesData("Product A", "Region 1", "2023-01-03", 200))

olap_processor = OLAPProcessor(olap_model) total_sales_by_region = olap_processor.total_sales_by_region() total_sales_by_product = olap_processor.total_sales_by_product()

print("Total Sales by Region:") print(total_sales_by_region) print("Total Sales by Product:") print(total_sales_by_product)
