Modern relational database management systems

Please assist with these two questions.

2. 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?

1. 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 commandments
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

2. 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?

In October of 2002, IBM made two key announcements. "The first was a vision of "e-business on demand," a blueprint for the future of computing. e-business on demand computing is characterized by four key traits?integration of systems, openness, virtualization of hardware and software resources, and autonomic computing.1 The second announcement concerned autonomic computing itself?IBM announced an organization, and a cross-company initiative, to deliver autonomic computing systems.

Autonomic computing is all about self-managing systems. At the core of the autonomic computing initiative is the concept that computers need to be more self-configuring, self-healing, self-optimizing, and self-protecting in order to reduce the overall complexity of a system. Therefore, more and more emphasis has been placed on design issues of database management systems for very good reasons."

Greenspun (2003) references that, "From an application ...

Solution Summary

Modern relational database management systems are discussed. The reason these are increasing are determined. The importance of the five commandments for data management are analyzed.
