You probably don't need a data dictionary

While efforts to build a data dictionary are often undertaken out of a zeal for documentation that we would normally applaud, in practice data dictionaries and data catalogs end up being a large maintenance burden for little actual value, and tend to very quickly become out of date. Instead of investing in building out traditional data dictionaries, we recommend a few different approaches for achieving the same goals in ways that are less burdensome to maintain and better serve the original objectives as well.
