Database vs. Data Warehouse: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
A database is a system for storing and managing data in a structured format, while a data warehouse is a centralized repository for integrating and analyzing data from multiple sources.
Key Differences
A database is designed for the efficient storage, retrieval, and management of data, typically in a structured format like tables. A data warehouse, on the other hand, is structured to store large amounts of historical data and enable complex queries and analysis.
