Has metadata cataloging features but needs changes in domain model
The tool's metadata cataloging is the most valuable feature.  The tool's domain model needs to be changed.  Alation Data Catalog is stable.  The solution is scalable.  Alation Data Catalog's deployment is easy. I rate it a nine out of ten. Deployment takes only two to three hours to complete.…

Business glossary is good, workflows are good but installation was difficult
I believe the relationship between business and technical terms could be improved, as well as the focus on data discovery. If we leverage the power of AI, we could provide more user-friendly outputs with relational insights between data. This is a core area for success. Any tool that focuses on data insights will add value. It's not just about linking clear data with clear business terms, but gaining insights is power and the key to success. So, I would like to improve the business and technical relations within OneTrust Data Governance. Customers mainly use OneTrust for compliance. For example, in Saudi Arabia, which is the top-selling country in 2023, there is a boom in data management investments due to digital transformation and government initiatives. They are heavily investing in data enrichment and data management. To succeed in this market, OneTrust needs to invest more and check the requirements from Saudi Arabian regulations. There are around 200 specifications to comply with. Once OneTrust meets those specifications, it will be able to sell more products. If OneTrust adapts well, OneTrust will see significant sales growth until 2030 in Saudi Arabia. An important thing to consider is to offer both on-premises and cloud deployment options. Currently, cloud-only solutions, especially on Azure, are not widely accepted. So, I would like to have an on-premises version as well. On-premises is crucial. If OneTrust can offer Google Cloud within Saudi Arabia, that would be good, but outside the country, Azure is acceptable for HIPAA compliance. So, in future, there should be both on-premises and Google Cloud options for cloud deployment.

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 provides a nice interface for connecting to the database, querying the data, and working on it."
"The solution's most valuable feature is the ALLIE AI feature."
"Alation Data Catalog was very useful for sharing SQL queries easily in a platform."
"Given the relatively low level of maturity, Alation's most relevant feature at the moment is a user interface that's easy to navigate, which helps us find and understand the data. So while Alation has a lot more functionality, our pain point right now is being able to easily find, understand, and trust the information to use it."
"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."
"The most valuable feature is cloud integration."
"The solution is used to query MySQL clients and store data and documentation."
"The tool's metadata cataloging is the most valuable feature."
"The tool gives us the ability to trace the path of an incident."
"The platform enhances the collaboration between data governance teams and other business units."
"The data flow analysis is especially valuable from a security perspective. It helps set a perimeter concerning security aspects."
"OneTrust DataGovernance has excellent on-premise data mapping and visualization capabilities."
"The product's valuable feature is its integration with other tools, such as risk management and risk assessment."
"This product makes it easy to manage personal data."
"OneTrust allows seamless management of multiple geolocations at one time and offers workflow automation based on location-specific parameters."
"One valuable aspect of the solution is its cloud-based nature. Users can just pay the fees and get started instantly."
 

Cons

"The tool's domain model needs to be changed."
"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."
"Alation Data Catalog does not provide end-to-end data lineage."
"It would be good if the tool could show the output from the records while querying."
"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."
"Although the solution performs far better in terms of data cataloging, its data governance capabilities need improvement."
"Data observability within Alation would be incredibly helpful for addressing these challenges"
"The tool is an amalgam. It's a collection of loosely integrated pieces and parts that don't work well together. There is room for improvement there. My team reached out to the support team, and their experience was not satisfactory."
"The process management capability could be improved."
"The integration with third-party products could be better."
"In OneTrust DataGovernance, there is room for improvement in creating customized email notifications in plain language and enhancing text editor features for form creation."
"To succeed in this market, OneTrust needs to invest more and check the requirements from Saudi Arabian regulations."
"Deployment is a big issue."
"The process management capability could be improved. It would be beneficial to have an authorization mechanism for users to process certain actions."
"Stability issues, like unexpected backend actions or data loss during updates, need to be addressed."
 

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."
"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."
"The solution is a little expensive."
"The product is worth every penny."
"The product cost was reasonable due to a discount for NGOs."
"The solution is a low-cost option."
"There is a licensing fee that we pay regularly."
