[Year 12 IPM] Redundancy

[Andrew Sutton]

Doesn't it also have to do with two fields in the one table that are
essentially giving you the same information? For example, In a table, You
shouldn't need the Age field if you have an accurate D.O.B. field.

Subject: [Year 12 IPM] Redundancy

Hi everyone,
Thanks for the help this list has provided throughout the year again!! Could
someone plese explain to me the meaning of 'data redundancy'? My
understanding is that it relates to loss of data and I also think it is
different to 'data integrity' but am not clear about these. It has come up
as a result of students having just completed the Insight Trial Exam paper.
Thanks in advance.
