Tableau Desktop Architecture

Tableau Desktop is a data visualization software and tool that allows you to connect to almost any data source and visualize and create interactive dashboards. The software architecture of Tableau Desktop is designed to support these features.


At the core of Tableau Desktop is the VizQL Server. This high-performance query engine converts user interactions into SQL queries and renders the visualizations. The VizQL Server is stateless, meaning it does not store any data but retrieves it from the data source when needed.


The VizQL Server can connect to various data sources, including relational databases, OLAP cubes, flat files, and web services. It can also connect to multiple data sources simultaneously, which allows you to combine data from different sources in your visualizations.


Tableau Desktop includes several other components, such as the Data Engine, a column-oriented database used to store the results of queries efficiently, and the Tableau Desktop Client, a graphical user interface that allows you to interact with the VizQL Server and create visualizations.


The Tableau Desktop architecture is designed to be scalable and extensible. You can deploy the software on a single server or a cluster of servers, and additional data sources can be added as needed.


Tableau Data Server

Tableau to Extract and Analyze Data from Multiple Sources

Tableau can connect to multiple data sources, including databases, spreadsheets, and cloud-based data warehouses, to extract and analyze data from various sources leading you to make better business decisions.

Some sources that Tableau works with include :

  • Amazon Redshift
  • Google BigQuery
  • Hive
  • Salesforce.com, and many more.

Tableau can help you visualize your data in many different ways. For example, you can create a bar chart to see how sales have changed over time or a pie chart to see the percentage of customers from each region. You can also create maps and scatter plots to see relationships between data points. Tableau is very flexible, so you can explore your data in diverse ways to find insights you might not have found otherwise.

Tableau to Visualize Data and Get Insights

As a data analyst, one of the most critical skills to pursue is effectively communicating your findings visually, and Tableau is an effective tool to make it possible. Let’s look at how to use Tableau to turn your data into beautiful, informative charts and graphs to understand your data better and make better decisions. We’ll also learn to use Tableau's more advanced features, like creating custom maps and table calculations. 

Creating Custom Maps

One of the most powerful features of Tableau is its ability to create custom maps. With Tableau, you can take any data set with geographic information and turn it into a beautiful, interactive map. You can even use custom maps to create heat maps and choropleth maps, two of the most popular varieties of visualizations for data with geographic information.

To create a custom map in Tableau, you'll need to start by connecting to a data set that contains latitude and longitude information. Once connected to your data, drag the latitude and longitude fields onto the view. Tableau will automatically recognize these fields as geographic information and create a map.

If you want to create a choropleth map, you'll need to drag a field representing some geographic area onto the view. For example, if your data set contains information about US states, you would drag the "state" field onto the view. Tableau will automatically color each state based on the data in the field that you dragged onto the view.

You can also create heat maps in Tableau. To do this, simply drag a numeric field onto the Color shelf. Tableau will automatically assign colors to your data based on the values in the field. Heat maps are a great way to quickly see which areas have higher or lower values.

Table Calculations

Table calculations can be used to perform complex data analysis in Tableau. With table calculations, you can quickly and easily answer questions that would otherwise be difficult or time-consuming.

To use table calculations, you'll need to start by creating a view containing the data you want to analyze. Once you've made your view, click the drop-down arrow next to the field you want to calculate. From the menu that appears, select "Compute Using" and then choose the appropriate option from the list.

For example, let's say you have a view containing sales data by region. If you wanted to see what percentage of total sales each area represents, you would click the drop-down arrow next to the "Region" field and select "Compute Using > Percent of Total". Tableau will then calculate the percent of total sales for each region and display it in the view.

You can also use table calculations to create Running Sums, Differences, and Moving Averages. To do this, click the drop-down arrow next to the field you want to calculate and select the appropriate option from the list. For example, if you wanted to see a running sum of sales by region, you would select "Running Sum > Region".

Parameters

With parameters, you can create visualizations that change based on user input. In our previous sales by region example, with a parameter, you could allow the user to select a region from a list, and then the view would only show data for that region.

To create a parameter, click the drop-down arrow next to the field that you want to use as a parameter. From the menu that appears, select "Create Parameter." Tableau will then display the "Create Parameter" dialog box.

In the "Name" field, enter a name for your parameter. In the "Data Type" field, select the appropriate data type for your parameter. In the "Current Value" field, enter a default value for your parameter.

Finally, click "OK" to create your parameter. Tableau will then add a control to the view that you can use to change the parameter's value.

Calculated Fields

With calculated fields, you can create new fields based on the data in other fields. For example, let's say you have a field containing sales data by region. You could create a calculated field showing each region's sales per capita.

To create a calculated field, click the drop-down arrow next to the field you want to use as a basis for the calculation. From the menu that appears, select "Create Calculated Field." Tableau will then display the "Calculated Field" dialog box.

In the "Name" field, enter a name for your calculated field. In the "Formula" field, enter the formula you want to use for the calculation.

Finally, click "OK" to create your calculated field. Tableau will then add the new field to the view.

Groups and Hierarchies


Groups and hierarchies are a great way to organize data in Tableau. With groups, you can combine multiple fields into a single area, which is pretty useful if you want to simplify a view or if you want to create a more granular view. In our sales by region data example, we could create a group that contains the fields for "North America" and "South America" and then use that group in your view.

To create a group, click the drop-down arrow next to the field you want to use as a basis for the group. From the menu that appears, select "Create Group." Tableau will then display the "Group" dialog box.

In the "Name" field, enter a name for your group. In the "Fields" section, select the fields you want to include in the group.

Finally, click "OK" to create your group. Tableau will then add the new group to the view.

Hierarchies are similar to groups, but they are typically used to organize hierarchical data. In the sales by region example, we could create a hierarchy that contains the fields for "Continent" and "Region." It would allow you to drill down from the continent to the regional level.

To create a hierarchy, click the drop-down arrow next to the field that you want to use as a basis for the hierarchy. From the menu that appears, select "Create Hierarchy." Tableau will then display the "Hierarchy" dialog box.

In the "Name" field, enter a name for your hierarchy. In the "Fields" section, select the fields you want to include in the hierarchy.

Finally, click "OK" to create your hierarchy. Tableau will then add the new hierarchy to the view.

Sets

Sets are a great way to filter data in Tableau. With sets, you can define a specific subset of data that you want to use in your view. For example, in our sales by region example, you could create a set that only includes data for the regions you are interested in.

To create a set, click the drop-down arrow next to the field that you want to use as a basis for the set. From the menu that appears, select "Create Set." Tableau will then display the "Set" dialog box.

In the "Name" field, enter a name for your set. In the "Field" drop-down list, select the field you want to use as a basis for the set. In the "Set Type" drop-down list, select whether you want to create a fixed or dynamic set.

If you want to create a fixed set, select the values you want to include. If you want to create a dynamic set, select the criteria you want to use to define the set.

Finally, click "OK" to create your set. Tableau will then add the new set to the view.

Tableau as a Drag-and-Drop Interface

Tableau is a drag-and-drop interface that makes it easy to analyze data. Simply connect to your data, and then drag and drop the fields you want to analyze into the Tableau workspace. Tableau will automatically create charts and graphs based on your data, making it easy to see patterns and trends. You can then customize your charts and graphs to suit your needs better. Tableau helps you make sense of your data and find insights you may have missed in a completely drag-and-drop UX environment.

Tableau as a Collaborative Platform

Tableau is a great platform for collaboration where multiple users can work on the same project simultaneously and see each other's changes in real-time. This makes it easy to brainstorm and collaborate on data projects.


Tableau is also a great platform for sharing data visualizations. Users can export their visualizations as images or PDFs or embed them on websites or blogs. Tableau's sharing features make it easy to share data visualizations with colleagues, clients, or the general public.

Why online Tableau Course is better than Offline Tableau Course
