What are disturbed databases? What are the advantages of distributed database?
A disturbed database is a database system in which data is distributed across multiple nodes or locations, often in different physical locations. Each node in the distributed database system typically stores a subset of the total data and may perform local data processing.
Advantages of distributed databases:
1. Improved reliability and fault tolerance: Distributed databases are more resilient to failures as the data is replicated across multiple nodes. If one node fails, the data can still be accessed from other nodes in the system.
2. Improved performance: By distributing data across multiple nodes, distributed databases can provide faster access to data for users. Queries can be processed in parallel, resulting in faster response times.
3. Scalability: Distributed databases can easily scale to accommodate large amounts of data and high volumes of transactions. New nodes can be added to the system to increase storage capacity and processing power.
4. Geographical distribution: Distributed databases can support data access and processing across different geographical locations. This can be useful for global organizations with offices in multiple locations.
5. Cost-effectiveness: Distributed databases can be more cost-effective than centralized databases, as they can use lower-cost hardware and distribute the workload across multiple nodes.
6. Enhanced data security: With data distributed across multiple nodes, distributed databases can provide enhanced data security. Data encryption, access control, and backup mechanisms can be implemented at each node to secure the data.
