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?

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.

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

Replication or data fragmentation, which is preferable in a distributed database system? If we combine fragmentation with replication, what do you think? Is it possible to tell whether a file is fragmented in a vertical or horizontal direction? You need to back up your assertion with an example.
