Difference Between Cognos vs Tableau
Business intelligence and a performance management tool to extract business information without any technical expertise is called Cognos. This was developed by IBM to analyze the data and prepare reports so that the information can be used in the growth analysis of the business. Open-source software to visualize data and put forward certain patterns in graphs so that different analyses can be made to understand the data is called Tableau. The visual representations are interactive that makes the user change and use it for various purposes. The raw data is easily converted in Tableau and used.

Key Differences between Cognos vs Tableau
Following are the key differences between Cognos vs Tableau:
- The main idea of any tool is the user interface and customer satisfaction. While Cognos can boost more power as it is created by IBM, Tableau has won the customer hearts by providing an interactive user interface with pleasing visualizations and no technical expertise in the field. Data can be continuously checked for new information and hence more insights are gained through Tableau. On the other hand, Cognos does not help in looking more into the data, and reports generation is really tough. This makes the users to move to Tableau.
- When the user wants to change the visual appearance of the tool, layouts and displays can be changed easily without knowing much about Tableau. Custom settings can be done easily in Tableau while it is difficult to change the custom settings in Cognos. Users must know in detail about the tool and look for the settings to change the layout.
- Any inputs of data are easily taken in for Tableau and the users can change it into a visual treat by drag and drop features so that anyone who looks into the data can get knowledge of what the data is trying to explain. this is not the case in Cognos as it can take only either excel or csv as input but cannot work with both together.
- Basic knowledge of Java and SQL is preferable in Cognos as Java is the supporting language in Cognos. Cognos SQL helps the users to create frameworks and create the queries in the tool to extract information. Tableau requires the knowledge of SQL and the process of extract, transform and load does not easily happen in this tool.
- Both Cognos and Tableau help the users to do analytics in offline mode. Tableau helps the users to gather data and then work offline by creating visualizations and reports to do the analytics. Corporate data sources can also be taken as input. While in Cognos, the user has to create online and offline models, and IT expertise is needed to incorporate both the models and present it in a collaborative form.
- Tableau gives more importance to visualization and hence any business intelligence functions can be selected for the user for data warehousing and ETL functions. Any tools or functions can be incorporated with Tableau for visualization so that graphs and tables can be created easily. Cognos has limited functionalities in terms of visualization and it focusses more on the reports and analytics side.
- In Cognos, external tools cannot be incorporated and users have to be satisfied with the inbuilt analysis and ETL tools which most of them may not prefer. In the tableau, with the visualization it offers, it also supports external tools to be used within the tool. This helps the users to look into various options and select the needed ETL tool for their business usage.
