A federated database management system (DBMS) is a type of DBMS that allows multiple autonomous database systems to be integrated into a single, unified system. Each individual database system in a federated DBMS remains independent and maintains its own data and processing capabilities, but they are able to communicate and share data with each other through a common interface.
Federated DBMSs are often used in large organizations or enterprises that have multiple databases spread across different locations or departments. By integrating these disparate databases into a federated system, organizations can improve data sharing and access, reduce data redundancy, and provide a unified view of the data to users.
Overall, federated DBMSs offer greater flexibility, scalability, and efficiency compared to traditional centralized DBMSs, as they allow organizations to leverage existing database systems while still providing a unified and integrated data management solution.

Federated Database Management System (Federated DBMS)
A federated DBMS is a database system that integrates multiple autonomous databases into a single, logical database, allowing users to access and manipulate data from different databases as if they were part of a single system.
Key Features:
- Heterogeneity: Integrates databases with different data models, structures, and storage mechanisms.
- Data Independence: Users can access data without understanding the underlying database systems.
- Transparency: Hides the complexity of multiple databases, presenting a unified interface to users.
- Integration: Allows data to be shared and accessed across different databases, improving data accessibility and interoperability.
- Centralized Management: Provides a central point of control for managing and administering all federated databases.
Benefits:
- Increased data accessibility and sharing: Enables users to access data from different databases without the need to access each database individually.
- Improved performance: Optimizes queries and reduces data movement by accessing data directly from the source database.
- Data consolidation: Aggregates data from various sources, reducing data redundancy and improving data quality.
- Centralized security and administration: Simplifies data security and administration by providing a single point of control for all federated databases.
- Scalability: Supports the integration of additional databases as needed, making it easy to expand the data landscape.
Architecture:
A federated DBMS typically consists of:
- Federation Broker: Central entry point that manages user requests and coordinates data access.
- Local DBMSs: Individual database systems that contain the actual data.
- Database Wrapper: Software that translates data and queries between the federation broker and local DBMSs.
- Data Dictionary: Stores metadata about the federated databases, including schema and data relationships.
Uses:
Federated DBMSs are commonly used in organizations with:
- Distributed data environments
- Mergers and acquisitions
- Data consolidation and integration projects
- Data sharing and collaboration initiatives
- Legacy system modernization
