hi everyone
A book "Distributed Database System" says
“If a predicate influences how fragmentation is performed, (i.e., causes a fragment f to be further fragmented into, say, fi and fj ) then there should be at least one application that accesses fi and fj differently.”
What does
“then there should be at least one application that accesses fi and fj differently.”
mean?
Does it mean that
at least one application should be satisfied completely by one of the new fragments.
1. Am I right?
“accesses fi and fj differently” is confusing me.
2. We can be required to make fragments once in a month in any organization. Sounds OK?
