What is Tableau ?

Tableau software is a data visualization tool that is used by Business Intelligence Analysts (BIA) to create reports and dashboards.

It is used by the BIA’s to transform the raw data into reports that are visually pleasing and understandable.

By why do Business Intelligence Analysts use data visualization tools ?

Data visualization tools are tools that are used to present visually pleasing analyzed data.

Representing data visually is better because it is easier to understand and more engaging than using only textual data.

So why do BIA’s use Tableau ?

Some of the reasons why BIA’s use Tableau include the following :

  1. Data visualization: Tableau can perform complex calculations that are needed to create customs reports and dashboards that the stakeholders need. These reports are used in analysis and can help the executives to make strategic decisions.
  2. Interactive reports : BIA’s can create interactive reports by using the built in functionalities of Tableau. Tableau has standard functionalities that make it easy to use and understand.
  3. It can handle large amounts of data: Tableau can easily handle a huge amount of data without compromising on its performance. It works by connecting to a data source such as SQL in order to pull the data that is used to create reports and dashboards.
  4. Scripting language capability : The BIA’s can incorporate scripting languages such as Python and R in Tableau. This helps enhance the built in functionalities in Tableau and enable the BIA’s to create powerful reports.
  5. Mobile Support functionalities : Tableau reports and dashboards are responsive and can automatically make adjustments based on the device being used.

So how does Tableau work exactly ?

Once the Business Intelligence Analyst (BIA) is ready to create their reports and dashboards, they would launch the Tableau desktop application which is used to create and modify the report and connect to the data source using a data connector .

Tableau works by connecting to a data source and extracting its data. It has built in connectors that can pull data from numerous data sources including the following :
