ETLtilnærminger
ETLtilnærminger refers to different methodologies and strategies employed when performing Extract, Transform, Load operations, a fundamental process in data warehousing and data integration. These tilnærminger (approaches) dictate how data is sourced, manipulated, and moved into a target system.
One common approach is the batch ETL. In this method, data is extracted from source systems at
Another significant approach is real-time ETL, often referred to as Change Data Capture (CDC) or streaming ETL.
A hybrid approach combines elements of both batch and real-time ETL. It might involve processing critical data
The choice of ETLtilnærming depends heavily on factors such as the volume and velocity of data, the
