Data Dictionary
The sooner it gets written down,
the easier it is to manage …
Why You Need It
It's something many firms
don't bother with. But it
can be really helpful.
Benefits of creating a Data Dictionary:
  • Correctness:  Documenting data
    specs helps you nail down the
    definitions everyone will use.
  • Consistency:  Approved methods
    for calculating and aggregating
    metrics helps you make sure
    all reports are accurate.
  • Easier Design:  You can develop and
    test new reports quickly, with results
    that are accurate and consistent.
  • Continuity:  Report code following
    a documented standard can help
    new IT staff and business users
    get up to speed faster.

Why You Need a
Data Dictionary

A centralized data dictionary tells analysts and report writers how to translate data into business information.

It's a major step forward in making sure that metric values remain correct & consistent across reports and analyses.

Fortunately, most of the base knowledge already exists in reporting code and staff experience. You just need to write it down.

Upgrade Your
SQL Skills

Even when your data specs are well-documented, the results are only as good as the SQL in the definitions.
