Tableau is a powerful and intuitive data visualization software that has gained significant popularity in recent years. It allows users to quickly create visually appealing and interactive dashboards, reports, and charts using large datasets, making it an invaluable tool for business reporting and data analysis. In this overview, we will explore the ins and outs of Tableau, including its key components, use cases, advantages, and how it compares to other popular data tools like Excel and Microsoft Power BI.
Tableau offers a suite of products that cater to various aspects of data visualization and analysis, including
Tableau Desktop is the primary tool for creating interactive data visualizations, reports, and dashboards. It provides a drag-and-drop interface that allows users to quickly create visually appealing charts and graphs without any coding knowledge. Users can connect to multiple data sources, blend and clean data, and even perform advanced business logic calculations using Tableau Desktop.
Tableau Desktop is the original flagship product of the Tableau suite and has largely spearheaded how data visualization tools have been built out today. It is designed with a non-technical business user in mind with the click-and-drag interface and is also capable of technically sophisticated visualizations and calculations to get exactly what you need from the product.
Tableau Server is an on-premise solution that allows organizations to host and manage their Tableau reporting environment. This provides control over security, integration, and customization while enabling users to access and collaborate on Tableau dashboards and reports through a web browser.
Tableau Server provides a lot of flexibility for organizations that want to take on the added management of hosting, infrastructure, and upgrades. While Tableau Server offers more robust options for integrating into existing IT infrastructure, large enterprises or organizations within heavily regulated environments tend to choose Tableau Server. Enter Tableau Cloud.
Tableau Cloud, formerly known as Tableau Online, is a fully-hosted, cloud-based solution that enables organizations to access and analyze data without the need for on-premises infrastructure. It offers similar functionality to Tableau Server but eliminates the need for organizations to manage their own infrastructure. Tableau Cloud is an easy plug-and-play solution for organizations of all sizes without the added overhead of administration.
With Tableau’s acquisition by Salesforce in 2019, there is an increasing focus on innovation and messaging for customers to move to Tableau Cloud - as Salesforce has the entirety of their ecosystem based in cloud applications as well.
Tableau Public is a free platform for sharing and discovering interactive data visualizations created by Tableau users worldwide. It is an excellent resource for learning and inspiration, as well as showcasing one's data visualization skills to a broad audience. Tableau Public’s Viz-of-the-Day is a great showcase to see what’s possible when using Tableau - just be mindful of publishing any content, as the data will be publicly accessible.
Tableau Prep is a data preparation tool that helps users clean, combine, and reshape data before visualizing it in Tableau. It offers an intuitive, visual interface for performing common data preparation tasks like filtering, aggregating, and merging data sources. Tableau’s Prep’s focus is mainly built for business users as no SQL knowledge is required. While it has the ability to handle complex data structures and cleansing operations, Tableau Prep is not intended as an enterprise-grade ETL (extract, transform, load) solution at scale.
Tableau Data Management is an add-on that helps organizations ensure their data is accurate, up-to-date, and easily accessible. It includes features for data cataloging, data quality checks, and automated data updates for Tableau Prep workflows. This can be an incredibly valuable add-on for organizations looking to organize data content better, understand data lineage (where data is being pulled from), and be able to schedule Tableau Prep flows to run without human intervention.
Tableau also provides ‘Ask Data’ capabilities within Tableau Server and Tableau Cloud to let users type questions in common language and get visualizations to answer with data. The visualized answers are created automatically without necessarily understand the nuances of the data.
Tableau is primarily used for:
Although Excel is a widely-used spreadsheet application, Tableau offers several advantages when it comes to data visualization and analysis:
Tableau Advantages
Ease of use: Tableau's drag-and-drop interface allows users to create complex visualizations quickly and easily, even without coding knowledge.
Interactive visualizations: Tableau enables users to create interactive, dynamic visualizations that can be explored and manipulated by end-users.
Scalability: Tableau can handle large datasets more efficiently than Excel, making it a better choice for working with big data.
Collaboration: Tableau Server and Tableau Cloud facilitate collaboration, allowing teams to work together on dashboards and reports.
Static visualizations: Excel produces static charts and graphs, which lack the interactivity and dynamism of Tableau visualizations.
Limited scalability: Excel struggles with large datasets, leading to slow performance and limited analytical capabilities.
Less intuitive for visuals: Creating complex visualizations in Excel often requires advanced knowledge of formulas and chart customization, making it less accessible for non-technical users.
Collaboration challenges: Excel files need to be shared manually, increasing the risk of version control issues and making real-time collaboration difficult.
Tableau is both a tool and a software suite. As a tool, it enables users to create data visualizations, dashboards, and reports. As a software suite, it encompasses a range of interconnected products, including Tableau Desktop, Tableau Server, Tableau Cloud, Tableau Public, Tableau Prep, and Tableau Data Management.
Tableau is designed to be user-friendly, with a drag-and-drop interface that makes it accessible to users without coding experience. However, like any software, there is a learning curve involved. The difficulty of learning Tableau depends on the user's familiarity with data analysis concepts, as well as their willingness to explore and experiment with the software.
No, Tableau does not require coding knowledge to create visualizations or perform basic data analysis. However, users with coding skills (e.g., SQL, R, or Python) can leverage their expertise to perform more advanced calculations and data transformations within Tableau.
While SQL is not required to use Tableau, having SQL knowledge can enhance the user's ability to work with data in Tableau. Users can write custom SQL queries to filter, join, or aggregate data before visualizing it in Tableau. Additionally, Tableau supports integrating with various SQL databases, allowing users to connect to and analyze data stored in these databases directly.
The original user design and intention of Tableau was to create an interface for business users to see and understand their data without having to directly write SQL code to make it happen. With that said an understanding of SQL will only make you more proficient in how Tableau interacts with data behinds the scenes.
One of the best parts of Tableau is the passionate community that creates a ton of great content, active forums, and ongoing learning opportunities. For starters, Tableau’s free training videos, tutorials, and educational webinars are a great spot to get started with bite-sized content - it’s how I started back in 2012.
There are several quality paid learning subscriptions through both popular content platforms (Coursera, Udemy, LinkedIn Learning) as well as customized classroom training packages delivered by Tableau Partners like DataDrive.
For technical support, the Tableau forums are filled to the brim with questions to almost every question you can imagine if you find yourself stuck on an error or specific concept. I recommend for new Tableau users to take a look at the following two community initiatives.
Lastly, there is the vibrant Tableau community that often identifies as #DataFam. Annually, Tableau recognizes Ambassadors and Visionaries, individuals who have contributed to the community above and beyond regarding education, content, and socializing of the tool.
Tableau's popularity can be attributed to several factors:
The best part of Tableau is that use cases exist across all industries for seeing and understanding data.
Although Tableau excels in many areas, it may not be the best choice for certain tasks:
Tableau continues to be in high demand due to the growing importance of data visualization and business intelligence. Tableau's ease of use, powerful analytics capabilities, and integration with various data sources make it a popular choice for organizations across industries. As the need for data-driven insights increases, demand for Tableau skills is expected to remain strong.
While both Tableau and Microsoft Power BI are popular data visualization and business intelligence tools, they have some differences:
Ultimately, the choice between Tableau and Power BI depends on the specific needs, budget, and existing infrastructure of the organization.
Tableau is a powerful and versatile data visualization and business intelligence tool that enables users to transform raw data into actionable insights. With its user-friendly interface and extensive features, Tableau has become a popular choice for organizations across industries.
When considering Tableau as a tool for your organization, it is essential to evaluate its capabilities in relation to your specific needs and requirements. It’s smart to compare against other popular analytics tools to make the decision about the best data visualization solution for your organization - and the true cost of ownership beyond the license pricing.
