BI Tools – Tableau


These days BI product are very common and everybody knows almost one of them. They can produce beautiful visualizations, dashboards, analytics, connect to any data; you can use them to cleanse/restructure your data, or build a machine learning project, combine them with your statistical and programming skills… all of them has their own advantages.
In my opinion You can find the best for all of your tasks/project You just need to know their features and what is their real strength.

In the first part of this series here comes Tableau.

“Our goal is to liberate the natural curiosity and creative energy stored in people everywhere, energy which is too often suppressed because it hasn’t had a proper channel for activity.” – Christian Chabot, CEO

“Tableau achieved extraordinary growth and has disrupted the market by appealing to business buyers, which propelled its “land-and-expand” strategy. Since its inception, Tableau has been sharply focused on making the analytic workflow experience for users easier, but at the same time giving them greater power to explore and find insights in data.” – Gartner – 2017

Tableau offers a highly interactive and intuitive visual-based exploration experience for business users to easily access, prepare and analyze their data without the need for coding. They offer this through three primary products: an authoring tool and two sharing/collaboration platform.

  • Tableau Desktop is the authoring tool, where you connect to data and create visualizations and dashboards to share with others.
  • For the sharing/collaboration products, we offer two options:
    • Tableau Server is an on-premise solution, which can be hosted on local hardware or through a cloud provider of your choice.
    • Tableau Online is a 100% cloud-based platform, hosted and maintained by Tableau.

Free trials are available for all of the products. You can download them and start finding insights in your data and get a feel for the experience of using Tableau. Lots of companies offer software that creates beautiful, visually appealing dashboards, but Tableau also delivers analytics that are easy to use and understand, flexible, and, most importantly, fast. Tableau’s core product strengths continue to be its visual data analytics and exploration, and analytic dashboarding capabilities for almost any data source — leveraging an extensive set of data connectors with both in-memory and direct query access for larger datasets.

In 2017 Gartner found, that ‘Tableau’s reference customers score its ease of use among the highest of all these vendors. […] All aspects of customer experience and operations (among Tableau’s reference customers) have improved this year compared with last year, and it scores above the vendor average for this Magic Quadrant. […] Tableau deployments are expanding and become a BI and analytics standard in most of its customer base, with survey customers either considering the platform to be “one of” (39%) or “the” (43%) enterprise standard. Moreover, Tableau’s reference customers report above-average deployment sizes.’


  • Tableau is enterprise ready – it’s enterprise-level security features manage authentication, permission, data and network security. Together, these capabilities provide a complete security solution that will serve the needs of a broad and diverse user base, whether internal to the organization or external on the Internet. The Tableau Server has passed the stringent security requirements of customers in the financial services, government, and healthcare sectors.
  • Tableau Server is highly scalable, serving the largest enterprises and tens of thousands of users:
    • Tableau Server:
      • Scale out by adding hardware to the cluster
      • Scale up by adding cores & memory to the machine
      • Data engine is also distributed for in-memory data
      • It even scales small by running effectively on VMs
    • Data Architecture
      • Leverages the power of the most sophisticated databases in the world
      • In-memory, when used, scales to 100s of millions of rows of data
      • In-memory, when used, is gentle on the memory consumption
  • has analytical depth
    • Rich calculation language
    • Forecasting and trending
    • What if analysis
    • Integration with R
    • Level of detail expressions
    • Time series analysis
  • supports associative search and goes beyond associative search
    • Actions and guided analytics
    • Flexible filters to include relevant values and all values
    • Most importantly, the end user can add elements to the view to do this exploration wherever they want to go.

People don’t always want to associate every part of their data, so Tableau provides flexibility. There are many ways to achieve similar results. Tableau does this with a combination of quick filtering, actions, and parameters.

  • has the ability to combine & transform data. Tableau can do data blending, we have built-in data prep, and have a rich ecosystem of partners to provide greater capabilities (Alteryx, Informatica, Paxata, Trifacta, LavaStorm, CloverETL, Snaplogic).
  • Tableau has the community like no other product. There is a network which really helps everyone – if You ask a question you will get the answer in minutes. And it’s not because there are Tableau employees behind it, this is because the whole community is about helping each other, there are the passionate people whose mission is help others succeed with Tableau.
  • no other similar product reinvests as much in the product as Tableau. Thanks to that there’re amazing new features in every release. But the best part is, that they’re following the trends of data analytics. This means the new features always what you was missing and you could be sure that if you’re waiting for something “mainstream” it will come to Tableau.
  • moreover there are infinite number of trainings and tutorials for Tableau. For every steps of learning Tableau you can’t find  videos, e-learnings, classroom or online trainings. There are webinars, and trainings in various topics, and of course you can get the certificates to prove your knowledge.

At the end let me quote the Tableau Zen Master, Andy Kiebel: ‘Tableau’s bread and butter is visual analytics. When Tableau says, they allow you to “see and understand your data,” they mean it. […] If you’re not using the power of visual analytics in your organization, you’re missing out on the true power of Tableau. No other product allows you to answer questions you have visually, at the speed of thought. You can literally SEE the answers to your questions.’
