What are the features of distributed database?

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.

What are the components of a distributed database system?

The required components of a distributed database management system can be categorised as hardware, communications media and software. Each processing site (or node) that forms the database system can consist of various types of hardware. Nodes can be mainframes, minicomputers or microcomputers.

What are the main reasons for distributed databases?

Distributed databases offer location transparency of data with local autonomy. This means that even though applications might not know where exactly the data resides, each site has the capability to control local data, administer security, keep track of transactions and recover when local site failures occur.

What are the key characteristics of a distributed architecture?

  • Resource sharing.
  • Openess.
  • Concurrency.
  • Scalability.
  • Fault tolerance.
  • Transparency.

What are the four different types of distributed database systems?

The next section of this chapter discusses the distributed architectures namely client – server, peer – to – peer and multi – DBMS. Finally, the different design alternatives like replication and fragmentation are introduced.

What are advantage of distributed database?

The database is easier to expand as it is already spread across multiple systems and it is not too complicated to add a system. The distributed database can have the data arranged according to different levels of transparency i.e data with different transparency levels can be stored at different locations.

What is the application of distributed database?

A distributed database is a set of databases stored on multiple computers that typically appears to applications as a single database. Consequently, an application can simultaneously access and modify the data in several databases in a network.
