Also, what are the features of a Ddbms?
In general, distributed databases include the following features:
- Location independent.
- Distributed query processing.
- Distributed transaction management.
- Hardware independent.
- Operating system independent.
- Network independent.
- Transaction transparency.
- DBMS independent.
Similarly, what are the issues of Ddbms? The design issues of Distributed Database

- Distributed Directory Management. •
- Distributed Query Processing. •
- Distributed Concurrency Control. •
- Distributed Deadlock Management. •
- Reliability of Distributed DBMS. •

Similarly one may ask, what is the importance of distributed database?
Because distributed databases store data across multiple computers, distributed databases may improve performance at end-user worksites by allowing transactions to be processed on many machines, instead of being limited to one.
What is Ddbms explain in detail?
A DBMS that enables end users or application programmers to view a collection of physically separate databases as one logical single-system image.

How distributed data storage is performed?
Distributed Data StorageIn this approach, the entire relation is stored redundantly at 2 or more sites. If the entire database is available at all sites, it is a fully redundant database. Hence, in replication, systems maintain copies of data.
What are the advantages and disadvantages of distributed database?

databaseHow do you control concurrency in a database?
Two Phase Locking Protocol also known as 2PL protocol is a method of concurrency control in DBMS that ensures serializability by applying a lock to the transaction data which blocks other transactions to access the same data simultaneously. Two Phase Locking protocol helps to eliminate the concurrency problem in DBMS.What is the main limitation of hierarchical database?
