I wish to know in simple English (Because my knowledge on the subject is poor), on an understanding of Normalization (functional dependencies), that occur within a database.
I wish to know the following:
an brief introduction to what it is.
A small amount of features that are used in order to full fill it's job.
and some advantages & disadvantages from using functional dependencies.
In case you are wondering this is for a college assignment, I've been up for about 28 hours and I haven't been able to write more than:
"A functional dependency is a link between two sets of attributes in a relation, we can normalize a relation by removing undesirable functional dependencies."
I'm even unsure as to if this is even correct or not, thank you for your kind responses(if any).
