define too much redundancy ¬†using -'sql,relational-database,normalization,redundancy'
I'm doing an online course and it gives the following relvar example and then says:
¬†¬†Hmm. Although answer and answercode are different in each tuple‚ÄĒmaking
¬†¬†each tuple technically unique‚ÄĒthe values for attributes id,
¬†¬†questionID, and answertype are exactly the same. Normalization is in orderd.
