Q: What is a federated database system?
Solution: A federated database system is a collection of autonomous databases that appear as one, allowing for distributed data access while maintaining individual database autonomy.
Steps: 4
Step 1: Understand that a federated database system is made up of multiple databases.
Step 2: Know that these databases are autonomous, meaning they can operate independently.
Step 3: Realize that even though they are separate, they work together to present data as if it is one single database.
Step 4: Learn that this system allows users to access data from different databases without needing to know where the data is stored.
