Featured Reviews

Senior Data and Analytics Consultant at a manufacturing company with 10,001+ employees
Increases data discoverability and boosts self-service analytics through enriched metadata and intuitive search
The best features that Alation Data Catalog offers are its search capabilities and the fact that it works with many different data platforms; it is essentially platform agnostic. The other piece that I really think is important is how easy it is to use as well as to manage. What makes the search capabilities of Alation Data Catalog stand out for me is the fact that every item within the catalog is indexed and searchable, as well as the filtering features that allow you to narrow down to just the types of assets that you need. Wildcard searches are also very helpful. It is a very intuitive tool, as long as you are using the filters. Alation Data Catalog has positively impacted my organization by allowing users to answer questions that they had without trying to track down an expert. This has saved them quite a bit of time and frustration. It has allowed them to solve problems they probably would not have been able to solve had they not had the catalog. We have been measuring the curation of content within the catalog that has gone up over time, and we have also seen the number of users in the catalog increase, as well as the amount of activity within the catalog increase. We were seeing about an average of about 20% increase month over month for the last few months.

Behavioral insights have powered personalized investor journeys and data-driven campaigns
I have not used Segment for more than a year, so I am not aware of its current evolution, but I know there was a migration from Segment to Adobe as a strategic decision by XP bank, which pointed out unified databases as an improvement area compared to Segment, where they effectively utilized AI for creative marketing campaign generation. The necessary improvements in Segment based on my experience focus on providing more tools for the marketing team, particularly using AI to create campaigns through images and short videos, enhancing communication with end customers via offer banners in a more automated and effective manner.
