We performed a comparison between IBM Cognos, QlikView, and Tableau based on real PeerSpot user reviews.
Find out what your peers are saying about Microsoft, Tableau, Oracle and others in Reporting."In terms of stability, I think that Cognos is more stable than Tableau and Power Bi because of its framework manager concept that allows us to import metadata and store it in the framework manager."
"Dashboarding, reporting, and ad hoc reporting are the valuable features of IBM Cognos."
"The most valuable feature is developing reports from different data sources, making it a reliable data source."
"The main difference that I like about Cognos compared to other solutions is its data splitting functionality. We have all our company data inside the Cognos environment and so we prefer to split the information Cognos itself. It's more efficient this way."
"The most valuable feature of IBM Cognos is security. The solution has updated features that other competitors' solutions come out with long after IBM Cognos has had them."
"A positive feature is Report Studio, where we create beautiful, complex reports."
"Stability-wise, I rate the solution a ten out of ten."
"This solution allows you to input a wide range of file formats."
"QlikView is a scalable solution that multiple users can easily use."
"We use QlikView for its cost-effectiveness and ease of integration with databases."
"If you correctly use the product for your use cases, it provides value for money."
"The most useful feature of QlikView for me is the QVD concept."
"This is a very cool application with endless options of creativity and visuals."
"The search feature: ability to see the related data."
"The solution is fast."
"The most valuable aspect is its extensive library on Microsoft, providing a robust framework for implementation."
"The most valuable feature is the geographic data analysis."
"The stability seems to be very reliable."
"It's very easy to visualize data with this product. The visualization maps of and frames that we have been able to cross-reference has been excellent."
"One of the most valuable features of Tableau is that it's a visual analytics solution, not just a dashboarding solution. Compared to Power BI, which is a dashboarding solution, there are no limitations with Tableau. For example, when you add a chart or a map to Power BI, it has a 3,000-point limitation. When you try to track your whole vehicle on the map, you only see the first 3,000 rows on the map, and Power BI doesn't tell you which part of the data is shown on the map. But Tableau doesn't have any limitations, which means that you can see five million data points on a map. It starts the project by creating the visuals that directly converts to SQLs. In that way, all the components have no limitations. When we compared Tableau to Power BI, we also found Tableau to be more fancy. Fancy means you can create more visual graphics and more visual dashboards. With Power BI, this isn't so—it's just some tables and some simple charts together. Tableau is more for business users who want to analyze data. Tableau can directly connect the analytics systems, like R or Titan, and get the results in screen, so it's a good solution for analytics scientists. It has some predefined capabilities to understand the data."
"Better interaction and less time spent with end users."
"The most valuable feature is the interface, which is user-friendly and intuitive."
"It is a very stable product. It doesn't break."
"Tableau Prep tool for data preparation is a most valuable tool."
"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."
"It would be good if the solution had conditional formatting."
"Tableau and Power BI are faster than Cognos."
"Chart quality: many other competitors have charts and graphics that look much better and that provide dynamic effects. Cognos doesn't."
"There are many problems with the product's stability part, making it an area where improvements are required."
"The AI-based features could be further enhanced by the solution."
"This product could use improvement in terms of usability for those with less technical know how."
"We would like to see development of the product's UI function, to make it more of a UI tool that can be configured as required."
"The only thing I would improve about it is the fact that it refreshes all the time, and when it does that, it just deletes all the options you had, all the filters that you had selected, so you need to select them from the beginning."
"Though the initial setup phase is simple, when it comes to the integration with the custom systems, the configuration and the compatibility sometimes take some more time."
"They should offer the capability to directly access data from SaaS environments, as it would simplify the migration process, and while it may seem like a minor enhancement, it would be beneficial to our clients."
"For me, it is important to have a mix, what is the "view" and what is the "sense", Qlik Sense. They have two tools, but for me it is important to have only one tool, which combines the functions that we have from one side and the other side."
"The user interface is old."
"Sometimes, dealing with complex reports requires more effort, which could be really improved."
"Improvement in collaboration, between that and publishing of reports and publishing of models."
"Installation and deployment could be made easier and quicker."
"A strict security measure is needed. I believe it is weak in terms of security."
"Many things have to be improved in Tableau. Right now, we make the calculation, and then we get that information. It would be better if business users could do that. I would ask the people at Tableau to provide that option to business users to get that information in one click. It would be better if they automated some calculations. There should be more automation in Tableau. However, there are many things in automation mode, but it is very limited at the moment. We need automation for people who do not know much about Tableau. It would also be better if there were good community support like in Alteryx."
"At the organizational level, increasing the servers' capabilities to support us as an enterprise tool."
"Areas for improvement would be visualization and augmented analytics. In the next release, I would like to see automated insights from the data added to the dashboard."
"The charts in Tableau are quite limited."
"From a downside perspective, some of the more advanced modeling techniques are actually fairly difficult to do. In addition, I just fundamentally disagree with the way you have to implement them because you can get incorrect answers in some cases."
"There are not enough language options. It needs to be offered in more than just English."
"The charting is overly complex in comparison with Power BI's"
