Overview
Data warehouses are essential for data-centric organizations, offering a scalable platform for managing data from various data sources. With an effective data warehouse architecture, organizations can access a centralized repository of current and historical data, supporting data mining and making it easier to analyze data effectively. Unlike data marts, which focus on a specific subject or use case, data stored in a data warehouse comes from across the entire enterprise. And unlike data lakes, which store raw data, data warehouses store cleaned and processed data ready for data analysis. As a result, data warehousing improves data quality and allows data scientists to perform more effective data analytics.
