Temporal Sales Data Analysis

Data Modeling Example for Temporal Queries:

To analyze sales data for the last quarter using temporal queries, follow these steps:

1. Data Preparation:

   • Ensure your sales data contains a date or timestamp field indicating when each sale occurred.

2. Temporal Query:

   • Use SQL to filter the sales data for the last quarter. The query should filter data based on the date range for the last quarter.

SQL Query Example:

SELECT *
FROM sales_data
WHERE sale_date >= DATEADD(quarter, DATEDIFF(quarter, 0, DATEADD(month, -3, GETDATE())), 0)
AND sale_date < DATEADD(quarter, DATEDIFF(quarter, 0, GETDATE()), 0)

3. Explanation:

   • This query selects all columns from the sales_data table where the sale_date is within the last quarter.
   • DATEADD and DATEDIFF functions are used to dynamically calculate the start and end dates of the last quarter.

4. Implementation:

   • Run this SQL query in your database management tool to retrieve sales data for the last quarter.

By utilizing temporal queries like this, you can easily extract and analyze data for specific time periods, enhancing your sales data analysis capabilities.
