Volume: Large volume of data generated from different sources, it could be customer-facing, financial data, equipment data, or logistical data.

Velocity: Operational Data generated from IoT devices, customer interactions with your product, or logistical support for delivery all are high-velocity data that are continuously ingested into data stores.

Variety: Data comes in all formats structured with defined schema and data characteristics to emails, texts, voice messages that are completely unstructured.
