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.

Head Of Information at Ericsson
Managing limited lineage across clouds has highlighted missing connectors but has supported basic cataloging
There are no specific areas of Google Dataplex I think could be improved because that is not our priority. To improve or enhance Google Dataplex, I would point out the connections; there is a lack of connections, and the variety of databases are not in a position to connect. I assess the usefulness of Google Dataplex's centralized management layer in simplifying data operations across environments as not there yet because the connections are lacking. If I look at the environments of something such as Ericsson, there are so many environments; to connect to each and every system, they are not there yet.

Quotes from Members

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

Pros

"Alation Data Catalog has positively impacted my organization by improving the data marketplace section, the data utilization section, and the quality of the data."
"The solution's most valuable feature is the ALLIE AI feature."
"The solution is used to query MySQL clients and store data and documentation."
"We do see a return on investment, though I cannot share exact numbers."
"The tool's metadata cataloging is the most valuable feature."
"The most valuable features of Alation Data Catalog are the simplicity in onboarding data sources, the security in securing the data sources, and the way the various users of Alation Data Catalog communicate with each other through a messenger."
"Alation Data Catalog provides a nice interface for connecting to the database, querying the data, and working on it."
"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."
"For Google Cloud data, Google Dataplex's AI-driven data classification has really helped; the out-of-the-box capabilities are good, and they have good classifiers."
 

Cons

"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."
"Alation Data Catalog needs to develop a lot in terms of data governance and would be improved with a built-in interactive data quality solution."
"We have had issues setting up the connectors and getting Alation's support team to resolve issues."
"Alation Data Catalog does not provide end-to-end data lineage."
"Alation Data Catalog is not user-friendly for business users. Its user experience is comparable to a Wikipedia page, lacking good visualization."
"Alation Data Catalog can be improved by treating areas that could incorporate best practices or improvements, such as identifying data domains, which refer to logical data groups customers, vendors, and other entities."
"I notice a couple of pain points with Alation Data Catalog: they can improve on the lineage perspective and improve their data sources integration."
"The interface is not user-friendly."
"I assess the usefulness of Google Dataplex's centralized management layer in simplifying data operations across environments as not there yet because the connections are lacking."
 

Pricing and Cost Advice

"The solution is a little expensive."
"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 platform is moderately expensive compared to the other competitors in the market."
"I don't have all the details on the pricing side, but the solution was more expensive than originally expected."
