Like any good puzzle, metadata management comes with a lot of complex variables. If not defined in a consistent manner, these variables can be as scattered and misleading as a large dataset is on its own.


That’s why you need to use data dictionary tools, which can help organize your metadata into an archive that can be navigated with ease and from which you can derive good information to power informed decision-making. Let’s look at some specific benefits that can be expected from the construction of a data dictionary.


You know what a dictionary is, but what is a Data Dictionary?

There’s a distinction between a data dictionary and a business glossary. A data dictionary is a tool that organizes and describes different variables indicated by metadata associated with a dataset.


A business glossary, sometimes referred to as a data glossary, is a broader tool. It defines terminology used by multiple departments across an enterprise. A business glossary should be understandable by anyone in the company.


A data dictionary is a tool specialized for IT system analysts and anyone who modifies those systems. Beyond this, a business data dictionary allows you to set more detailed parameters about the data. These include:

  • Columns that contain unique identifiers, allowing for easier data navigation
  • Permissible inputs for particular data, such as the allowed values in a specific row or column
  • Text descriptions of data objects that allow for greater interpretation and application of data than a basic label


Having a data dictionary means any potential user will be able to understand the data in a data warehouse. By defining the metadata that is created by the data stored in the system, you can isolate relevant information and identify which variables impact the results of the data.

Why Have a Data Dictionary? 

#1 Reason: There’s too much metadata to keep in one person’s head. 

In large datasets, metadata management can suffer from the same limitations as raw data. Quite simply, there can be too much metadata for any one person to organize and maintain.


Try to memorize an Excel file. Remember the titles and qualifications of every row and cell, and you’ll know what we mean.

Beyond making metadata easier to identify and locate, a data dictionary also allows for the construction of reports and dashboards. These give users more information for stronger business decisions.


A data dictionary is a resource useful for many different teams, including designers, programmers, and application builders. Improvements are delivered to multiple processes across your enterprise organization.
