Modern relational database management systems have been around for a relatively short period of time. As time goes by, more and more emphasis has been placed on design issues, especially database modeling. What is the reason for this increased emphasis?

Wheaton's (2007) article states five "commandments" (i.e. best practices) for data management. Pick one of the commandments from below, explain it and the rationale for it, and then discuss a data example from your current or previous workplace that illustrates the importance of that commandment.

The commandments are:

1.The data must be maintained at the atomic level.
2.The data must not be archived or deleted except under rare circumstances.
3.The data must be time-stamped.
4.The semantics of the data must be consistent and accurate.
5.The data must not be overwritten
