Cause of Data Redundancy
Flat file database with tables - very simple row and column structure
- Because of this there are no relationships between the data , therefore creating duplicate entries as in data redundancy for example the Agent Richard Brown's name has been entered three times, the same property address has been entered more than once, agents details have been entered more than once
- By creating a relational database, the repitition of Richard Browns name would be be entered once and once only.
