I think Electronic health records (EHRs) combined with wearable device data from thousands of patients. for example, Apple Watch is a great example of a device that generates Big Data in healthcare.
1. Volume:
It collects a large amount of data continuously such as heart rate, steps, sleep patterns, and ECG readings.
2. Velocity:
Data is recorded in real-time and can be synced instantly to the user’s phone or cloud.
3. Variety:
Different types of data: numeric (heart rate), categorical (activity type), time-series (sleep patterns), and notifications from health apps.
4. Veracity:
Some measurements may be inaccurate due to movement, sensor errors, or incorrect usage, so data quality varies.
5. Value:
When analyzed, it helps track fitness, detect irregular heart rhythms, monitor chronic conditions, and provide insights for personal health.
