12-27. In this chapter, you learned about four dimensions along which poor data might impact a business. For a company of your choice, such as a hospital, identify one or more scenarios that could serve as a good example for each type of impact.

4 Dimensions

1. Operational data are transient rather than historical.

2. Operational data are not normalized. Depending on their roots, operational data may never have been normalized or may have been denormalized for performance reasons.

3. Rather than being comprehensive, operational data are generally restricted in scope to a particular application.

4. Operational data are often of poor quality, with numerous types of inconsistencies and errors.
