a) Hierarchical
b) Network
c) Distributed
d) Decentralized
Decentralized is not a traditional type of database.
Here’s a brief explanation of the other options:
- Hierarchical: Data is organized in a tree-like structure with a single root.
- Network: Data is organized in a graph-like structure with multiple parent-child relationships.
- Distributed: Data is stored on multiple computers connected by a network.
Decentralization is more of a concept or architecture than a specific database type. It refers to systems where control and management are distributed among multiple entities rather than centralized in a single location. While decentralized systems can use various database technologies, they are not a database type themselves.
In essence, while decentralized databases are emerging as a concept, they don’t fit into the traditional categorization of database types like hierarchical, network, or distributed.
