What is DDBMS with example?
A Distributed Database Management System (DDBMS) contains a single logical database that is divided into a number of fragments. Every fragment gets stored on one or more computers under the control of a separate DBMS, with the computers connected by a communications network.
What are the four different types of distributed database systems?
Distributed Database System
- Fragmentation –
- Replication –
- Heterogeneous Database:
- Homogeneous Database: In a homogeneous database, all different sites store database identically.
Where is distributed database management system used?
DDBMS is widely used in data warehousing, where huge volumes of data are processed and accessed by numerous users or database clients at the same time. This database system is used to manage data in networks, maintain confidentiality and handle data integrity.
What are the uses of distributed system?
Distributed computing allows different users or computers to share information. Distributed computing can allow an application on one machine to leverage processing power, memory, or storage on another machine.
Is MongoDB a distributed database?

What is the difference between DBMS and DDBMS?
Database management system is any software that manages and controls the storage, the organization, security, retrieval and integral of data in a specific database, whereas DDBMS consist of a single database that is divided into many fragments.
What are the main software modules of DDBMS?

Is Oracle a distributed database?
