1.	Which of the following is not a feature of a good relational design?(a) Specifying primary keys(b) Specifying foreign keys(c) Preserving integrity constraints(d) Allowing redundancy of attributesI got this question in unit test.My doubt is from Features of Good Relational Design in division Relational Database Design of RDBMS
Answer» CORRECT OPTION is (d) Allowing redundancy of ATTRIBUTES To elaborate: Allowing redundancy of attributes makes it very difficult for data extraction. So, It is not a good relational design feature.
