Most people use Relational databases to simplify work. All a Distributed DBMS is a Relational Database spread over a wider area than the workplace. Fragmentation and Date replication are complications and experience says that Distributed DBMS are built to make life simpler

What are distributed-databases in dbms?

Distributed databases in a DBMS are databases that are stored on multiple computers across a network. They allow for data to be spread out and accessed simultaneously from different locations, which can improve performance and scalability. Distributed databases can enhance fault tolerance and reduce the risk of data loss.


What is query processor in distributed dbms?

The query processor in a distributed DBMS is responsible for receiving and analyzing queries from users or applications, determining how to execute the query across multiple distributed nodes, and coordinating the execution of the query to retrieve the desired data efficiently. It optimizes query performance by considering factors such as data distribution, network latency, and data transfer costs across distributed nodes.

What is the difference between ddbms and parallel dbms?

A distributed database management system (DDBMS) manages databases that are stored on multiple computers, often in different locations. A parallel database management system (parallel DBMS) uses multiple processors to perform operations on a single database, improving performance by dividing tasks among these processors. In essence, DDBMS focuses on data distribution and replication across different sites, while parallel DBMS focuses on high-speed data processing using multiple processors.


Which DBMS features do you find most useful and why?

Some of the most useful DBMS features include data security mechanisms like encryption and access controls, scalability options for handling growing amounts of data, and performance tuning tools for optimizing query performance. These features help ensure data integrity, protect against security threats, and allow for efficient storage and retrieval of data as needed by the application.
