What does the term 'data latency' refer to in a data warehouse?
Correct Answer: Data latency is the time delay between data generation and its availability for analysis.
- Step 1: Understand that data is created or generated from various sources, like transactions or sensors.
- Step 2: Recognize that this data needs to be collected and processed before it can be used.
- Step 3: Identify that data latency is the time it takes from when the data is created to when it is ready for analysis.
- Step 4: Realize that lower data latency means data is available for analysis more quickly, while higher latency means a longer wait.
