From orders to a sales report
A shop may need its order records in a data warehouse to make sales reports. A pipeline copies the records from the shop’s system, checks for missing details, converts amounts into one currency, and sends the results to the warehouse. Software performs these steps at set times or as new orders arrive.
An ETL process is one common kind of pipeline: it collects, prepares, and loads data.
Check that the data arrived
If a pipeline misses or repeats an order, a report can be wrong even though the pipeline appeared to run. Teams check how many records arrive, watch for delays, and plan how to retry or correct failed steps.
