Chapter 3. Using Metadata - The Key Points of this Chapter
Metadata are useful only when they help an organization in a tangible manner.
From a practical perspective, metadata can be used to assess and improve
technical systems, data management, and data reporting and use.
Data profiling uses many of the metadata items in this chapter to characterize
the quality and other features of a data set.
Business rules describe the policies and guidelines an organization has
established to manage its businesses processes, data elements, and data sets
related to those processes.
