Sticky Note
The purpose of normalization is to Identify a suitable set of relations that support the data requirements of an enterprise. Followings are the characteristics of a suitable set of relations EXCEPT?
  1. The minimal number of attributes necessary to support the data requirements of the enterprise.
  2. Attributes with a close logical relationship (described as functional dependency) are found in the same relation.
  3. Implementation of a method that depends on the type of the object it is applied to (overriding).
  4. Minimal redundancy with each attribute represented only once with the important exception of attributes that forms all or part of foreign keys, which are essential for the joining of related relations.
Explanation
  • Normalization organizes a database to reduce redundancy and dependency.
  • A suitable set of relations has minimal attributes, logical grouping, and minimal redundancy.
  • Object-oriented concepts like overriding are not related to normalization.
