Discuss the trade-offs between data replication and consistency in a distributed database, considering factors like latency and fault tolerance.

When using a distributed database system, when should we employ replication vs data fragmentation? Is it possible to mix replication with fragmentation? Where do lateral and vertical fragments vary and what do they mean? Could you provide me with an illustration of your argument?

Discuss the concept of distributed database replication strategies, including synchronous and asynchronous replication. When is each strategy most appropriate?

When should distributed database systems employ data replication to address data fragmentation if it is a problem? It seems that the processes of fragmentation and replication are incompatible. What distinguishes vertical fragmentation from horizontal fragmentation? Give me an example so I can better grasp your position.

Discuss the challenges and trade-offs involved in implementing deadlock avoidance mechanisms in distributed databases. How do these mechanisms affect system performance and availability?

Describe different approaches to data replication in distributed databases, such as primary-backup, multi-master, and eventual consistency. What are their trade-offs?

Explain the concept of data replication in distributed systems. What are the benefits and challenges of data replication, and how can consistency be maintained in a replicated environment?
