Who are we to say? Distinguishing inter

Do you have any specific examples to back up your assertion that many-to-many links cannot be stored in a relational database? If you have, we'd appreciate it if you'd tell us about them.

When attempting to handle data fragmentation in distributed database systems, when is it appropriate to utilise data replication? It would seem that the processes of replication and fragmentation cannot coexist in any meaningful way. What is the function of horizontal fragmentation in contrast to the role that is played by vertical fragmentation? You will need to present an example for me to buy into your line of reasoning if you want me to do so.

When should data replication be used in distributed database systems to address data fragmentation? It seems that the methods of replication and fragmentation are mutually exclusive. In comparison to vertical fragmentation, what is the role of horizontal fragmentation? If you want me to accept your argument, you'll need to provide an illustration.
