centralized:

All the information is stored in a single system. To access the data, all users must go to the same system.

Data is distributed:

Across multiple nodes, allowing for speedy access. “Rather than relying on hardware to provide high availability, the Database Management software is designed to duplicate data between the servers,” allowing it to detect and handle faults.

Federated:

Provides data without requiring additional persistence or data duplication from the source. It combines numerous independent databases into a single colossal item. For heterogeneous and distributed integration projects, this database architecture is ideal.

Loosely Coupled:

Component databases create their federated schema, which necessitates using a multi-database language to contact other component database systems.

Tightly Coupled:

Component systems develop and published into an integrated federal schema using independent methods.
