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.
Andres-Martinez - PeerSpot reviewer
BI Data Analytics Engineer at Targa Research
Helps with metadata management, saves time, and allows us to do impact analysis on any changes
There are always ways to improve things. For example, we can use AI to be able to find out something. When we are typing something, if we don't know the exact term, Artificial Intelligence would be useful to find terms that are phonetically or syntactically similar. Instead of having to type in the exact name, they can provide those in the list. So, they can provide AI support for the search because when you have thousands and thousands of terms, it is hard to remember all the names. There were some issues when drawing the data models. If you have more than 500 or 600 tables, it takes a long time to display those in the right position on the screen. That can also be improved. They need some caching and some parallel pipelines working on the backend in order to divide it into sections.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We have improved data quality and accuracy, made informed decisions faster while reducing risks, and ensured compliance by enabling security and efficient access."
"The most valuable feature is cloud integration."
"We had some of our data science engineers, who had built out some cloud-based data and data products for users. They were spending a lot of their time, up to 30 to 35% of their time, answering questions about the data and helping people understand how to use it. Once they were able to document that information within Alation, they were only focusing on around 5% of the high-value questions that really couldn't be solved through the catalog itself. It freed them up to be more productive, it made their end-users more productive, and it made the adoption rate of their data products rise more quickly because people were able to get to using them."
"We had nothing before, so we can't compare anything we used before with what we've got now, but what we've got now is infinitely better."
"Alation Data Catalog positively impacts my organization by improving data efficiency, data quality, and collaboration, allowing analysts to spend more time on analysis instead of searching and preparing, so they can just start their analysis."
"The tool's metadata cataloging is the most valuable feature."
"Alation Data Catalog has positively impacted my organization by allowing users to answer questions that they had without trying to track down an expert, saving them quite a bit of time and frustration and allowing them to solve problems they probably would not have been able to solve had they not had the catalog."
"We can customize templates based on our use cases."
"When you combine it with data lineage, every time you need to make a change, it allows you to do impact analysis on any changes and then connect to the end-users or data stewards so that they can be aware that a change is coming."
"When you combine it with data lineage, every time you need to make a change, it allows you to do impact analysis on any changes and then connect to the end-users or data stewards so that they can be aware that a change is coming. That's one of the main benefits we use it for."
"The data catalog feature is pretty good."
 

Cons

"The product's data governance features need improvement."
"Alation Data Catalog doesn't support end-to-end lineage. By that, I mean the ability to trace the movement of data from when it first comes into our organization to where it's consumed."
"I know that this has been on their roadmap and they're working on it, but as a whole, there's an untapped reservoir of capabilities within their article features that could be used and built upon."
"The interface is not user-friendly."
"Alation Data Catalog can be improved by enhancing their lineage capabilities to make it easier for us as users to search the lineage without having to use the Alation Data Catalog user interface."
"I know that this has been on their roadmap and they're working on it, but as a whole, there's an untapped reservoir of capabilities within their article features that could be used and built upon."
"We have had issues setting up the connectors and getting Alation's support team to resolve issues."
"Alation Data Catalog is not user-friendly for business users. Its user experience is comparable to a Wikipedia page, lacking good visualization."
"There were some issues when drawing the data models. If you have more than 500 or 600 tables, it takes a long time to display those in the right position on the screen."
"There is room for improvement with respect to the connector and how to connect to the structured and unstructured database."
"There are always ways to improve things. For example, we can use AI to be able to find out something. When we are typing something, if we don't know the exact term, Artificial Intelligence would be useful to find terms that are phonetically or syntactically similar. Instead of having to type in the exact name, they can provide those in the list. So, they can provide AI support for the search because when you have thousands and thousands of terms, it is hard to remember all the names."
 

Pricing and Cost Advice

"A three-year agreement is better than a one-year rolling 12-month agreement from a price point of view. I'd recommend looking at a three-year deal because you can't stand up a catalog and produce value in 12 months."
"The solution is a little expensive."
"I don't have all the details on the pricing side, but the solution was more expensive than originally expected."
"The platform is moderately expensive compared to the other competitors in the market."
"I am not very familiar with its pricing. I know it is not cheap, but it is also not super expensive. It depends on the company size. For a company making $1 million, it is very expensive. For a company making 10 million and above, it might be okay."
"Erwin Data Catalog is very expensive."
