The process in which a data warehouse is updated regularly is known as ETL (Extract, Transform, Load).

Here's a step-by-step explanation:

1. Extraction: This is the first step in the process. Data is extracted from various sources, which can be in different formats (like text files, databases, etc.).

2. Transformation: Once the data is extracted, it is then transformed into a format that can be easily analyzed. This could involve cleaning up the data, aggregating it, and making it consistent.

3. Loading: The final step is to load the transformed data into the data warehouse, where it can be accessed and analyzed.

So, the correct answer is b. ETL.
