We performed a comparison between Dremio and IBM Cognos based on real PeerSpot user reviews.
Find out what your peers are saying about Databricks, Microsoft, Alteryx and others in Data Science Platforms."Dremio gives you the ability to create services which do not require additional resources and sterilization."
"We primarily use Dremio to create a data framework and a data queue."
"Dremio allows querying the files I have on my block storage or object storage."
"Dremio enables you to manage changes more effectively than any other data warehouse platform. There are two things that come into play. One is data lineage. If you are looking at data in Dremio, you may want to know the source and what happened to it along the way or how it may have been transformed in the data pipeline to get to the point where you're consuming it."
"The most valuable feature of Dremio is it can sit on top of any other data storage, such as Amazon S3, Azure Data Factory, SGFS, or Hive. The memory competition is good. If you are running any kind of materialized view, you'd be running in memory."
"Everyone uses Dremio in my company; some use it only for the analytics function."
"It is a stable product."
"Integration with Office can enable the 'download' mode of storytelling."
"Stability-wise, I rate the solution a ten out of ten."
"The most valuable feature is developing reports from different data sources, making it a reliable data source."
"We use the account statement report. When you use an account in HSBC, you receive various types of accounts, such as the stock market, fixed accounts, credit cards, and business accounts. We can create one consolidated report called CCS support, which includes all these accounts. In that statement, we are consolidating all those accounts."
"The most valuable features are Report Development (Functionality) and Information Distribution (Flexibility)."
"IBM Cognos improves the effectiveness of the sales team."
"The comprehensiveness or broadness of the software functions or business intelligence functions that it provides is valuable. It is also quite easy to use and user-friendly."
"Dremio doesn't support the Delta connector. Dremio writes the IT support for Delta, but the support isn't great. There is definitely room for improvement."
"It shows errors sometimes."
"We've faced a challenge with integrating Dremio and Databricks, specifically regarding authentication. It is not shaking hands very easily."
"They have an automated tool for building SQL queries, so you don't need to know SQL. That interface works, but it could be more efficient in terms of the SQL generated from those things. It's going through some growing pains. There is so much value in tools like these for people with no SQL experience. Over time, Dermio will make these capabilities more accessible to users who aren't database people."
"I cannot use the recursive common table expression (CTE) in Dremio because the support page says it's currently unsupported."
"Dremio takes a long time to execute large queries or the executing of correlated queries or nested queries. Additionally, the solution could improve if we could read data from the streaming pipelines or if it allowed us to create the ETL pipeline directly on top of it, similar to Snowflake."
"Tableau and Power BI are faster than Cognos."
"The data uploads that we do, such as Excel files, have a lot of restrictions. If we can make it a bit more user-friendly, allowing us to have more flexibility it would be a great help."
"It would be good if the solution had conditional formatting."
"Compared to Tableau and PowerBI, the IBM interface is easier to use. However, the drag-and-drop functionality isn't as straightforward. Formatting is also more challenging in the cloud than in other applications, like Power BI. Also, if you encounter an issue, it takes more time to resolve it on the formatting side."
"Data modeling needs to be improved. We use the ETL process, and when we get errors, we then need to identify which structural change is required. The error messaging should be better. They should be descriptive rather than semantic."
"The visualization aspect needs to be improved and I believe, this is being resolved in upcoming versions."
"The tool needs to improve the connectivity since I see that, at times, there is a need to increase the memory in the database."
"It could have more options for themes."
