Data Warehouse
A centralized repository that stores structured, processed data from multiple sources for analytics and ML training.
Overview
A data warehouse consolidates data from various operational systems into a single, organized repository optimized for analytical queries and reporting. Unlike operational databases optimized for transactions, data warehouses are designed for complex queries across large datasets.
Role in ML
Data warehouses serve as the source of training data for many ML systems. Cloud warehouses like Snowflake, BigQuery, and Redshift integrate with ML tools for feature engineering, model training, and batch prediction. The quality of ML models depends heavily on the quality and breadth of warehouse data.
