Differentiate between a database and data warehouse?..

Answer / Laxmi Balmiki

Although databases and data warehouses both store data, they have several key differences:
- Database is used for transactional processing and operational reporting, while a data warehouse focuses on analytical processing and business intelligence.
- A database stores current and up-to-date data, whereas a data warehouse stores historical data for analysis purposes.
- Databases are typically normalized to minimize redundancy, while data warehouses are denormalized for improved query performance.
