I don't understand Collation? (Mysql, RDBMS, Character sets)

Question

I Understand Character sets but I don\'t understand Collation. I know you get a default collation with every Character set in Mysql or any RDBMS but I still don\'t get it! C

Answer 1

Collation is information about how strings should be sorted and compared.

It contains for example case sensetivity, e.g. whether a = A, special character considerations, e.g. whether a = á, and character order, e.g. whether O < Ö.
