Type your answer here... "the distribued system is a collection of independent computers work as a single system for the user" prof--- Kaushlandra Pratap singh(DBIT)
Distributed systems refer to a network of independent computers that work together to achieve a common goal, while distributed database systems specifically involve databases that are spread across multiple locations. Distributed database systems focus on storing and managing data across various nodes in a network, whereas distributed systems are more general and encompass a broader range of functionalities beyond data management.
Distributed databases offer advantages such as improved scalability, increased availability, and better fault tolerance compared to centralized databases. They also provide better performance by reducing network latency and enabling data to be processed closer to where it is needed. Additionally, distributed databases can offer better data security by replicating data across multiple locations.
A database is a collection of related data organized for quick search and retrieval, usually stored on a single computer system. A distributed database is a database in which parts of the database are stored in multiple locations but managed by a centralized control. Distributed databases are used to improve performance, reliability, and scalability by allowing data to be spread across multiple servers or locations.
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.
There are several reasons for building distributed database systems. Firstly, distributing data across multiple nodes allows for better scalability and improved performance as the workload is distributed. Secondly, it enhances fault tolerance and reliability as data is replicated across multiple nodes. Finally, distributed database systems can provide better availability as accessing data from multiple nodes allows for load balancing and redundancy.
File systems are used to store and organize files on a computer's storage device, whereas database systems are used to store and manage structured data in a way that allows for efficient retrieval, updating, and querying. Database systems provide features like data integrity, security, and concurrency control that are not typically found in file systems. Additionally, database systems use structured query languages (SQL) to interact with the data, while file systems do not offer such querying capabilities.
1 Explain architecture of Distributed Database systems? Also, explain the reasons for building distributed database systems?

differences between document management and database technology
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.
Redundancy means duplicacy of data or repetitive data. In distributed database case the data is stored in different systems . So the answers is yes there can be redundancy of records / data.In distributed database , data is stored in different systems. Since the data is distributed there is redundancy of records.

=A database physically stored in two or more computer systems. Although geographically dispersed, a distributed database system manages and controls the entire database as a single collection of data. If redundant data are stored in separate databases due to performance requirements, updates to one set of data will automatically update the additional sets in a timely manner.==Read more: [http://www.answers.com/topic/distributed-database#ixzz2R7Aof5Cb http://www.answers.com/topic/distributed-database#ixzz2R7Aof5Cb]=
Replicated Allocation ie copies of one or more database fragments are stored at several sites.
A distributed computing system requires each machine attached to the network to has specific software allowing them to talk to each other. A distributed virtual systems allows the machines on a network to talk to each other without the use of central software.
