What is the difference between full extraction and incremental extraction in data extraction techniques?
- Full extraction extracts all data every time, Incremental extraction extracts only the changed or new data since the last extraction
- Full extraction extracts data based on conditions, Incremental extraction extracts all data every time
- Full extraction extracts data only once, Incremental extraction extracts data continuously
- Full extraction extracts data without any criteria, Incremental extraction extracts data based on a fixed schedule
Full extraction involves extracting all data each time, while incremental extraction extracts only the changed or new data since the last extraction. This helps in optimizing the extraction process and reduces the load on the source system.
