Key to successful data governance is the management of metadata—the frame of reference giving data its
context and meaning. Effectively governed metadata provides a view into the flow of data, the ability to perform
an impact analysis, a common business vocabulary and accountability for its terms and definitions, and finally
an audit trail for compliance. The management of metadata becomes an important capability enabling IT
to oversee changes while delivering trusted, secure data in a complex data integration environment. Good
metadata management tools, then, play a central role in holistic data governance.
