• Data Warehouse is used for long-term analysis, showing trends over time, and predicting the future.
Purpose :
• DBMS (Database Management System) purpose are Operational tasks, managing day-to-day transactions.
• Data Warehouse purpose are analytical tasks, facilitating complex querying and trend analysis.

Here's a example of the difference between DBMS and Data Warehouse :
DBMS (Database Management System) :
Imagine your grocery store has a filing cabinet. Each drawer holds different folders :
• One folder for products, listing details like price and quantity.
• Another for customer info, with names and purchases.
• And one for daily sales records, noting what was sold.
This filing cabinet acts like a DBMS, helping you manage day-to-day store operations efficiently.
Data Warehouse :
Now, picture a big room with shelves in your store. Each shelf holds different types of data :
• One shelf for yearly sales records.
• Another for customer feedback and reviews.
• And one for tracking inventory history.
Together, these shelves form a data warehouse, allowing you to analyze trends and make strategic decisions for your grocery store's future.
