“Our idea was to build more than a data catalog. We don’t only want to have the tables, the columns, and the documentation, we want to expand our domains to go beyond data literacy.”

Terms and Categories

Organize your glossary
the way you want

A Term is the fundamental unit of your glossary. It can be a KPI definition, metric formula, or business taxonomy — it’s up to you. The special part? Group collections of Terms into Categories, and create multi-level hierarchies that mimic the way you work.

“We needed something that could help bridge the gap between publishers and consumers, so we adopted a data catalog. Atlan is the layer that brings a lot of the metadata that publishers provide to the consumers, and it’s where consumers can discover and use the data they need.”

“Each engineer was answering questions 10 to 20% of their time. And then you multiply that over a certain number of employees across the team, that’s hundreds of hours per month that you’re losing in terms of productivity. Atlan reduced it really, really significantly.”
