Ataccama ONE Platform and Atlan compete in the data management and governance sector, each offering distinct strengths. Atlan appears to have an edge due to its intuitive design and integration capabilities, which are especially beneficial for business users.

Features: Ataccama ONE Platform excels in data profiling, cleansing, and effective quality checks, along with straightforward match and merge rule setups. Its drag-and-drop feature and ability to function in diverse environments are notable. Atlan is recognized for its out-of-the-box connectors and automated lineage tracking, which enhance data cataloging efficiency. The intuitive design facilitates metadata management and data governance practices while integrating with communication platforms and automating processes.

Room for Improvement: Ataccama ONE Platform struggles with large data volumes, requiring enhanced integration capabilities and better documentation. It could benefit from improved flexibility in interfacing tools like Collibra. Atlan could improve its governance capabilities and streamline workflows for smoother integration with business data, enhancing lineage tracking, user interfaces, and support documentation.

Ease of Deployment and Customer Service: Ataccama ONE Platform accommodates diverse deployment environments, including on-premises and hybrid cloud setups, with generally positive technical support though some users mention delays with complex issues.

Streamlines reusable data quality rules and has highlighted the need for richer logic and documentation

I worked in Ataccama ONE Platform from version 5 and now we have version 15, which has improved a lot. However, there is still considerable scope for improvement because Ataccama ONE Platform was not that great around 2020 when I started working with it. There can still be more features including writing any logic, improving more keywords for logic building, and enhancing address validation, based on my understanding. User experience is actually good; I do not have any complaints or feedback on that. However, the documentation part can be improved because documentation is key for any organization or tool. If anything is needed for understanding, you have to rely on documentation. Ataccama's documentation has potential for improvement.

Automation has transformed data quality workflows and now saves significant time and cost

A quick specific example of how our team uses Atlan to automate a manual or high-risk task is the robust functionality for the quality management of metadata sets. The most helpful thing here is all the dashboards that provide visibility in one place. We use this tool because it is very easy and integrable with other data sources, which is very convenient and time-saving. By switching to Atlan, we have increased our productivity and saved a lot of business time through automation. My team, whether technical or non-technical, adapted Atlan very quickly because of its simple and intuitive user interface. The best features Atlan offers include the ease to extract and modify the data. We can do very quick and smooth integration. It is an open-source framework that provides extension capability to the APIs it uses. Tons of automation help to automate tedious and time-consuming tasks, thereby reducing error and saving time and cost. It is extremely user-friendly and intuitive to navigate, especially the user interface. Atlan has positively impacted my organization by saving time and money while consolidating our metadata sets. Integration with Amazon and Tableau have definitely sped up our time to value. We have saved fifty-five percent of our time through the automation of tedious and time-consuming tasks. Extraction of data is easy. In this data catalog solution, data modification is really simple and easy. Integration with other software is very seamless and easy, thereby simplifying our workflow. Atlan is very scalable and helps to grow our organization while catering to our needs. It enables the team to automate manual and high-risk tasks to make them error-free as much as possible and save time and cost. It is a very cost-effective tool that should be highly adaptable and usable in any organization.

Quotes from Members

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

Pros

"The data profile itself is excellent. You can understand the quality of the data in layman's terms."

"The ease of use of the user console is valuable."

"By understanding the existing data from various source systems, we were able to arrive at the requirements for a data quality plan, and create a separate plan to improve the data quality."

"Customer service was excellent, and I would give it a ten out of ten."

"Ataccama ONE Platform has positively impacted my organization by being much cheaper compared to other DQ tools and providing very good support."

"The software itself is quite good and met all my requirements."

"I was able to ascertain that elements of information was or was not of value to the migration process, thus saving money in the migration project."

"Ataccama ONE Platform has positively impacted my organization significantly, as it enables us to understand our enterprise data and clean it more effectively to gather proper insights."

More Ataccama ONE Platform pros

"By switching to Atlan, we have increased our productivity and saved a lot of business time through automation."

"The AI part is integrated for enriching metadata engagement, making it a comprehensive tool."

"Atlas is quite intuitive."

"Overall, I rate Atlan a nine out of ten."

"The technical support services are good."

"Atlan has positively impacted the organization since it helps in discovering already available assets, allowing for reduction of redundant ingestion of external data and reduction of time to market for any project."

"By switching to Atlan, we have increased our productivity and saved a lot of business time."

"They also offer automated lineage embedded in the connectors, allowing us to track where the data is coming from and where it's going. We find it very efficient in cataloging data sources.

More Atlan pros

Cons

"I have heard that the licensing and setup costs are quite high, especially if we try to connect for a support call."

"It was a little tough for my team to learn and start using Ataccama ONE Platform because the documentation at that time was not good."

"I believe it would be beneficial if it could enhance its flexibility to connect with a wider range of downstream systems beyond just Excel and Postgres."

"Speaking specifically about the version we use, version 12.3, I'm unsure if this has been addressed in subsequent versions. One improvement I'd like to see pertains to the language used in certain components, especially in data quality checks. The language complexity posed a challenge for beginners. Although we had on-site assistance from Ataccama, making it manageable for us, some individuals found it difficult to comprehend, necessitating additional support. The provision of a comprehensive guide for on-premise installation can also be enhanced. The lack of detailed information on the solution's workings and the overwhelming nature of notifications, with extensive content, were areas of concern. Streamlining the notification content in newer versions would significantly expedite issue resolution."

"I would not say Ataccama ONE Platform is one hundred percent stable. I would rate it at seventy percent stable."

"They could focus more on marketing the product. The current marketing strategy is not working."

"The non-free version has much more capabilities and I did not have the occasion to try it."

"For improvement, I feel there is a size issue. Whenever we create a monitoring project with a large amount of data, such as multiple catalogs, it starts failing."

More Ataccama ONE Platform cons

"Atlan can be improved by integrating agents that can support users in finding assets of interest."

"The product could be improved by offering scheduled email reports for managed assets."

"Customer support for Atlan is not so proactive."

"One of the main areas for improvement is its governance capabilities. Atlan supports only basic out-of-the-box workflows, and it becomes challenging to customize features like how data owners should approve access to data assets."

"There are some improvements. There is a feature called Playbooks, which basically allows me to automate certain activities that would otherwise be manual. It's a very interesting feature, but there is room to improve it because, depending on the task you automate, the playbooks seem to have a hard time handling the task. So, it could be improved there. Even though it's a great feature, it can evolve further."

"One area that could be improved is the capability to find duplicates of datasets."

"Certain UI changes could make Atlan more user-friendly."

"The challenge is in the lineage, where it requires improvement. Atlas needs to capture areas where organizations use less known applications."

More Atlan cons

Pricing and Cost Advice

"Our licensing model wasn't user-specific; instead, we paid fees for the engine and maintenance. As we didn't have a support contract, maintenance fees were likely nonexistent. Regarding the upgrade, we had an account for the initial two or three years, and considering the features provided by the solution, the pricing was reasonable."

"The product is reasonably priced."

"There is no need to buy a license. You can just download it and use it for free."

"Despite not being extremely low-cost, the pricing appears reasonable, making it a profitable and viable choice for companies that prioritize data security and adhere to specific policies."

"We pay per-user license. It's a different classification model than with other solutions, where they usually charge you for resources. So, that was a better model for us. And because of this difference in models or classification, it was cheaper for us to go with Atlan."
