The database can be of two types either distributed or centralized . In distributed database the data is in different systems. In centralized database the data is in a single central system.
We can categorize database as either distributed or centralized . In centralized database the data is in a single centralized system. While In distributed database the data is in different systems .

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.

Different between distributed and decentralized on database?
Distributed databases are spread across multiple nodes or locations, while decentralized databases operate without a central authority or control. Distributed databases may have a centralized component for coordination, while decentralized databases use consensus algorithms for decision-making. Decentralized databases offer higher resilience and security against single points of failure compared to distributed databases.
Discuss the relative advantages of centralized and distributed databases?
Centralized databases offer easier management and maintenance due to a single point of control, while distributed databases provide better scalability, fault tolerance, and performance due to data distribution. Centralized databases are simpler to design and enforce consistency but can become a single point of failure, whereas distributed databases can continue functioning even if some nodes fail but are more complex to manage and balance data distribution. Both approaches have their own strengths and weaknesses depending on the specific requirements of the system.
What are advantages of rdbms over dbms?
Some advantages of relational database management systems (RDBMS) over traditional database management systems (DBMS) include data integrity through the use of constraints, normalization to reduce redundancy, support for ACID transactions, and standardized SQL language for data manipulation. RDBMS also offer scalability and flexibility for complex data structures and relationships.
What are the disadvantages of a DDBMS?
Some disadvantages of a distributed database management system (DDBMS) include increased complexity in data management, higher costs for implementation and maintenance due to the need for specialized hardware and software, and potential security risks associated with data transmission over networks. Additionally, ensuring consistency and coordination among distributed nodes can be challenging.
Why fragmentation and date replication are useful in Distributed DBMS?
Fragmentation and data replication are useful in Distributed DBMS for various reasons. Fragmentation helps in breaking a large database into smaller fragments that can be stored on different nodes, improving data access and query processing speed. It also enables data distribution and parallel processing, which can enhance overall system performance. Data replication, on the other hand, involves creating multiple copies of data on different nodes. This ensures data availability and fault tolerance, as if one copy becomes unavailable, the system can retrieve data from other replicas. It also enables load balancing and improves data accessibility in a distributed environment.

Why are distributed systems complex than centralized systems?
Distributed systems are more complex than centralized systems because they involve multiple nodes interacting over a network, leading to challenges such as network latency, node failures, and data consistency. Coordinating and managing these interactions across multiple nodes require additional considerations such as fault tolerance, concurrency control, and communication protocols.
Is there an advantage if a top weight jockey rides a horse with high handicap?
The main advantage is that the weight is distributed over the wither rather than in a lead bag right across the hos back.
What advantage do reports have over printed forms in database?
Reports allow you greater flexibility in grouping and summarising data compared to printed forms.
Advantage of relational model over hierarchical model?
Use of primary keys less data redundancy compatible with inconsistencies associated with database anomalies
Advantages and disadvantages of distributed system over centralized system?
Advantages of Distributed Systems over Centralized ones 1:Incremental growth:Computing power can be added in small increments 2:Reliability:If one machine crashes, the system as a whole can still survive 3:Speed: A distributed system may have more total computing power than a mainframe 4:Open system: This is the most important point and themost characteristic point of a distributed system. Since it is an open system it is always ready to communicate with other systems. an open system that scales has an advantage over a perfectly closed and self-contained system. Economic:ANd Microprocessors offer a better price/performance than mainframes Disadvantages of Distributed Systems over Centralized ones 1:As i previously told you distributed systems will have an inherent security issue. 2:Networking:If the network gets saturated then problems with transmission will surface. 3:Software:There is currently very little less software support for Distributed system. 4:Troubleshooting:Troubleshooting and diagnosing problems in a distributed system can also become more difficult, because the analysis may require connecting to remote nodes or inspecting communication between nodes. To design my own distribute system i would do the following: 1:Distributed users always pose a threat to be exposed by hackers.Therefore I'l create groups of users and will provide them constrained access to data. 2:Authentication required by all users who use the system. 3:encryption..that is for message protection, 4:The whole Domain is also to be protected via firewalls..so i would install good Firewalls. 5:Would install good anti viruses on my machines which are a part of the distributed system, as these systems are prone to the domino effect that is if one system gets effected the whole network will be susceptible to becoming effected. 6:Design: As far as possible I'll keep the design simple and as local as possible.Will probably use a virtual private network. Will use machines that are compatible with each other. Will enforce secure access on all users. Will probably save the most important, the database on another well equipped machine so that it has a system that is only dedicated to look after the database.
