Discussion on: Data Normalization, with storage being so cheap what’s the point? http://itknowledgeexchange.techtarget.com/sql-server/data-normalization-with-storage-being-so-cheap-whats-the-point/ Wed, 09 Jul 2008 09:41:06 +0000 http://wordpress.org/?v=wordpress-mu-1.2.1 By: Jgunja http://itknowledgeexchange.techtarget.com/sql-server/data-normalization-with-storage-being-so-cheap-whats-the-point/#comment-54 Jgunja Wed, 14 May 2008 06:45:56 +0000 http://itknowledgeexchange.techtarget.com/sql-server/data-normalization-with-storage-being-so-cheap-whats-the-point/#comment-54 I agree with Denny that we still need to normalise data even with the storage becoming cheap. Particularly, if we are storing the same data in so many places in an enterprise, then it becomes a problem for the enterprise (a) to maaintain the data - you may have more than one system maintaining the same data - thus maintenance cost increased unnecessarily. (b)to determine which data is up-to-date - if we have more than one place to store the same data, then it would difficult to determine which data is correct. Thus if a customer having given his particulars to one business area fins that another business area in the same enterprise does not have this information, the enterprise would not be considered customer-oriented. It would not be able to use the data effectively, as the data is not consistent. It would hinder its own goals for improving its bottom line or increasing its sales.
