- Extract: Gather sales data from various databases.
- Transform: Filter and aggregate relevant data, such as total sales per region.
- Load: Export the transformed data into a CSV file.
Benefit: Provides a portable and easily accessible format for analysis, sharing, or archival purposes.
c. Batch Processing for Periodic Data Updates
Scenario: A company updates its inventory system daily with data from multiple suppliers.
ETL Process:
- Extract: Collect inventory data from supplier APIs overnight.
- Transform: Standardize data formats and resolve discrepancies.
- Load: Update the inventory database with the latest information.
Benefit: Ensures inventory levels are current, preventing stockouts or overstock situations.
d. Using Webhooks for Real-Time Data Synchronization
Scenario: An e-commerce platform wants to update its CRM in real-time when a new customer makes a purchase.
ETL Process:
- Extract: Capture purchase events via webhooks.
- Transform: Format customer and purchase data appropriately.
- Load: Immediately update the CRM with the new information.
