Just to clarify my understanding of Database Indexing...
I just want to make sure I understand what's going on when we index a table in a database.
Does it create a literal index, as in A, B, C, D etc?
So when I run :
SELECT * FROM table WHERE col = "Something"
the database starts looking from the 'S' index rather than the top of the table?
Or is there a bit more to it than that?
