IBM Cognos Analytics vs. Tableau Public

I use predictive analytics techniques, which can help me predict my future sales based on collected data, giving me insight into my market's trends.This market data can be analyzed, giving me the opportunity to gain in-depth insight into my market's competition and positioning it competitively, aided by developing strategies to improve my marketing approach.

Tableau Public is great, especially if you're new to the platform or considering implementing it within an organization. The Public version has most of the capabilities of the full version, with extensive community documentation to troubleshoot issues you may run into. Additionally, there are many resources to check out Public workbooks from other users and communities: a GREAT learning resource to figure out new, innovative ways to visualize and present data. It is perfect for evaluating public datasets, for doing exploratory data analysis, or contributing to cross-organizational or extracurricular projects that may benefit from more sophisticated data analysis and exploration. Tableau Public, because it stores to the cloud and has limitations on connectivity (ie, cannot connect to SQL servers) is not suited for confidential, financial, PII, etc., data, and care should be taken to avoid including sensitive data in any of the Tableau Public workbooks used by an individual or organization.

• Data Visualization: Plenty of options exist for multiple use cases, and dashboards are easy to implement and customize.
• Integration with IBM Watson: makes it easy to use Watson AI features (NLP etc.) on your data.
• Its advanced analytics functionalities with powerful pattern detection/prediction models.

• Tableau Public can work with data that are differently formatted, such as MS Excel, .txt file, Google Sheets, not sure about MS Access.
• GUI interface of Tableau Public is not that hard to start working on; Also, it can generate codes for the operations and so it is relatively easy to visualize and correct mistakes.
• Lots of Tableau Public users upload their work to the online community, users can easily find very good figures/graphs that are similar to their problems and so they can use these figures/graphs as templates to modify and make their own ones.

Incentivized

• API integration is not upto the mark with very limited options.
• Laptops get overheated when the tool is used from moderate to heavy use. Also, there is a lag in the tool times.
• Licensing & Maintenance can go from cheap to expensive depending on the scope.
• Lot of scope to improve the customer support & its not upto the industry standards.

Incentivized

• The biggest drawback to the Public version of Tableau is that any data used in the program is 'public' and therefore not secure: workbooks are saved to the cloud, rather than locally
• Tableau Public limits data ingestion to 10 million rows per source
• Limited connections - can't connect to SQL databases to ingest data (must be through CSV, Access, TDE, or text files)

It took my BI team one year to become productive at developing useful content on the IBM Cognos platform. After this year, the reports being developed for a client were stale and no longer relative to the ever changing needs of the business client. Given the same opportunity, I would select a platform that allows the team to quickly produce BI content. Fail fast and recover quickly!

It's free, right? I'll keep using the free version. So the real question to ask is this? Will I pay $999 for the Personal version or $1,999 for the Professional? Yikes! That is a big stretch. I'm not sure about that. The product comparison chart is at: http://www.tableausoftware.com/public/comparison

We have a strong user base (3500 users) that are highly utilizing this tool. Basic users are able to consume content within the applied security model. We have a set of advanced users that really push the limits of Cognos with Report and Query Studio. These users have created a lot of personal content and stored it in 'My Reports'. Users enjoy this flexibility.

Tableau public is a great training tool to understand the basics of Tableau before buying it. A great tool to extend Excel's visualization and to publish data for others. Not useful for anything you need secure. No ability to access databases. Static information only.

Reports can typically be viewed through any browser that can access the server, so the availability is ultimately up to what the company utilizing it is comfortable with allowing, though report development tends to be more picky about browsers and settings as mentioned above. It also has an optional iPad app and general mobile browsing support, but dashboards lack the mobile compatibility. What keeps it from getting a higher score is the desktop tools that are vital to the development process. The compatibility with only Windows when the server has a wide range of compatibility can be a real sore point for a company that outfits its employees exclusively with Mac or Linux machines. Of course, if they are planning on outsourcing the development anyways, it's a rather moot point

Overall no major complaints but it doesn't handle DMR (Dimensionally Modeled for Relational) very well. DMR modelling is a capability that IBM Cognos Framework Manager provides allowing you to specify dimensional information for relational metadata and allows for OLAP-style queries. However, the capability is not very efficient and, for example, if I'm using only 2 columns on a 20-column model, the software is not smart enough to exclude 18 columns and the query side gets progressively larger and larger until it's effectively unusable.

Why is their web application not working as fast as you think it should? They never know, and it is always a a bunch of shots in the dark to find out. Trying to download software from them is like trying to find a book at the library before computers were invented.

Onsite training provided by IBM Cognos was effective and as expected. They did not perform training with our data which was a bit difficult for our end-users.

The online courses they offer are thorough and presented in such a way that someone who isn't already familiar with the general design methodologies used in this field will be capable of making a good design. The training environments are provided as a fully self contained virtual machine with everything needed already to create the environments. We've had some persisting issues with the environments becoming unavailable, but support has been responsive when these issues arise and straightening them out for us

I found it sufficient, and fast. I could easily "kick the tires" with Tableau on my data so I got up and running fast.

The implementation was handled very well. The initial implementation exposed a lot of disagreement between our campuses and departments as to how we define data. This was not entirely unexpected, but I thought that we did a nice job as a team to work through some of these challenges.

Start at the end and work backward. Identify the business case / issue and questions the end users have, then identify the data needed, and where to get it.

Power BI is stronger for quick ad-hoc analysis and dashboards, but IBM Cognos Analytics is better when consistency, precision, and mass distribution matter. Tableau is best for interactive analysis, while IBM Cognos Analytics is better for standardized, repeatable enterprise reporting. Sigma shines for customizable dashboards and drill-down analysis while IBM Cognos Analytics holds an edge in data discovery and visualization.

Tableau public is Free and no subscription is required whereas Tableau Desktop is a paid subscription. if there is no private or confidential data it's easy to Tableau public and share reports with people. Tableau public has same features and options same as desktop. its easy for students or beginners to signup and start learning/build reports.

The Cognos architecture is well suited for scalability. However, the architecture must be designed with scalability in mind from day one of the implementation. We recently upgraded from 10.1 to 10.2.1 and took the opportunity to revamp our architecture. It is now poised for future growth and scalability.

• The platform can be pretty pricey.
• Convoluted contracts and they fine you for any breach during audits.
• Things are changed between releases without any warning and break.
• It is second to none at being able to customize list and crosstab type reports.
• You can easily set up a report to be emailed out every day and even have it export the report to a shared folder.
• On-prem environments can be scaled up pretty much as much as you would like.

• We have saved costs on Dashboarding tools thanks to the free tools within Tableau Public
• Streamlined reporting
• Time saved with easier data preparation features
• Professional looking dashboards and visualisations
