Within the data value chain, which activity focuses on transforming raw data-through cleaning, enrichment, and aggregation-so that it becomes trustworthy and ready for analysis?
Data visualization
Data ingestion
Data storage
Data processing (data preparation)
The data processing (or preparation) stage of the value chain is where raw, often inconsistent data is transformed into a structured, high-quality form. Tasks such as data cleansing, deduplication, normalization, and aggregation occur here. These steps make the data reliable for subsequent analytics. While ingestion moves data into the platform, storage simply persists it, and visualization presents insights to users, only processing prepares the data itself for meaningful analysis.
