What is the difference between a dimension and a measure in Tableau?

A dimension is a categorical or qualitative variable that represents the characteristics or attributes of the data, A measure is a quantitative or numerical variable that can be aggregated or summarized.

Be able to give a Story about Tableau as an example

A story is a set of worksheets or dashboards that work together to tell a message.

You're a store manager creating a Tableau report that shows how profit and sales vary across product categories. How would you do this?

A treemap is the best way to determine how profit and sales vary across product categories. It shows the color and size of rectangles. With sales as the row and category as the primary dimension, profit would determine the color, while sales would dictate the size. Adding other dimensions, such as subcategories, would provide a more precise view of which items are generating more profit.

What is the order of performance for data types?

Boolean > int > float > date-time > string

What Will the Following Function Return? Left(3, "Tableau")

It will return an error because the correct syntax is: left(string, num_chars). So, it should be: Left("Tableau," 3) Left returns a specific number of characters from the start of the given string. If the correct syntax is followed, the result would be 'Tab.'

What does "view in tableau" mean?

The term [...] refers to how data from a source is shown in a worksheet. A [...] can be anything. It could be a plot, a chart, a graph, or even a table. Then, all of these points of [...] are put together on a dashboard to make a single story and show how they all fit together.

How can you create a calculated field in Tableau?

To create a calculated field in Tableau, you can right-click in the data pane, select "Create Calculated Field," and then enter the desired formula or expression using Tableau's calculation syntax.

What is Tableau's Mission Statement?

We help people see and understand data. We Believe In Power for the People.

What are the different Tableau products? (There's Seven Of Them)

- Tableau Server - Tableau Online - Tableau Public Server (Now Tableau Cloud) - Tableau Desktop - Tableau Reader - Tableau Mobile - Tableau Prep Builder

What are some characteristics of a Measures?

- [...] contain numeric, quantitative values that you can measure (such as Sales, Profit) - [...] can be aggregated Example: Profit, Quantity, Rank, Sales, Sales per Customer, Total Orders

What are some characteristics of a Dimension?

- [...] contain qualitative values (such as names, dates, or geographical data) - You can use [...] to categorize, segment, and reveal the details in your data. Example: Category, City, Country, Customer ID, Customer Name, Order Date, Order ID

What is data blending in Tableau?

... is a technique in Tableau that allows you to combine data from multiple data sources based on a common field or key. It enables you to analyze and visualize data that resides in different databases or files. [...] is a more advanced way of combining two different data sources. Ex: one data source shows the annual sales of a product in other countries, and another shows the profit and loss for each country each month. Different levels of segregation mean that a simple join won't work in this case. The first step will be to add up all the values in the second data source based on the year. After that, a join will be done. Tableau makes it very easy to do all of these steps because Tableau can find the field of country and year that is shared by two data sources and do a post-aggregate join on its own.

What is the purpose of a parameter in Tableau?

...in Tableau allow users to define dynamic values that can be used to control various aspects of the visualization, such as filtering data, changing calculations, or modifying colors.

What is the Difference Between .twbx And .twb?

.twbx: The .twbx contains all of the necessary information to build the visualization along with the data source. This is called a packaged workbook, and it compresses the package of files altogether. .twb: The .twb contains instructions about how to interact with the data source. When it's building a visualization, Tableau will look at the data source and then build the visualization with an extract. It can't be shared alone as it contains only instructions, and the data source needs to be attached separately.

In Tableau, what are marks?

A [...] card helps add details to the chart because it can give different colors based on a category and change the size of a line, circle, or bar in the chart based on any measured value. [...] card is also used to put labels on the chart and add details to the view. It is also used to control the tooltip and how it looks, which should improve the visualizations.

What is a Calculated Field?

A [...] field is used to create new (modified) fields from existing data in the data source. It can be used to create more robust visualizations and doesn't affect the original dataset.

What is a workbook?

A [...] is a complete set of sheets, dashboards, and stories you have made on tableau desktop or public, saved on your local system or published on tableau public. You can get the [...] for tableau public by clicking on the link to its website.

What is a Parameter in Tableau? Give an Example.

A [...] is a dynamic value that a customer could select, and you can use it to replace constant values in calculations, filters, and reference lines. Example: when creating a filter to show the top 10 products based on total profit instead of the fixed value, you can update the filter to show the top 10, 20, or 30 products using a parameter.

What is a Data Culture?

A [...] is the collective behaviors and beliefs of people who value, practice, and encourage the use of data to improve decision-making. As a result, data is woven into the operations, mindset, and identity of an organization. A [...] equips everyone in your organization with the insights they need to be truly data-driven, tackling your most complex business challenges.

What is a Tree Map?

A [...] is used to represent hierarchical data. The space in the view is divided into rectangles that are sized and ordered by a measure. Scenario: Show sales and profit in all regions for different product categories and sub-categories. Analysis: The larger the size of the node, the higher the profit in that category. Similarly, the darker the node, the more sales in that category.

What does "Tableau Developer" mean?

A [...] knows how to take raw data and use it to make data visualizations and get valuable insights. A [...] should be able to make advanced dashboards that are easy for other people to use and help them easily understand the data.

What is a Heat Map?

A [...] map is used to compare categories using color and size. In this, we can distinguish two measures. Scenario: Show sales and profit in all regions for different product categories and sub-categories. Analysis: A [...] map is not only defined by color, but you can also use its size. Here we define the size by sale by dragging the Sales tab to Size under marks card, comparing profit and sales through the color and size. A quick way to use a heatmap would be to learn about the human body's structure and see how warm it is based on the temperature of different organs. If the red and yellow colors are used, the red parts will show where the temperature is the highest.

What is a scatter plot?

A [...] shows how two or more measures, with or without dimensions, relate to each other. To make a [...], you need at least one measure in each row and column. You can then use different dimensions to add more details—marks over color and information on the card. In a [...], the data points are drawn in a space, and their shapes depend on the values in the measures.

Define Tableau in eight words or less.

A. Tableau's power and ability to make sense of raw data B. Its role as a key business intelligence tool C. How it works best with big data

In Tableau, what are aggregation and disaggregation?

Aggregation is the simple idea of taking the average of the values in a given column of a data set. If a report shows how the price of a product has changed over time, aggregation can help find its average value. Most of the time, Tableau automatically groups a set of data. The opposite of averaging is disaggregation, which can be helpful if a user wants to look at each data point separately. You can also use both grouped and ungrouped data in the same worksheet.

How Can You Display the Top Five and Bottom Five Sales in the Same View?

Be able to make this image:

What is the Difference Between Joining and Blending?

Blending: Combining the data from two or more different sources is data blending, such as Oracle, Excel, and SQL Server. In data blending, each data source contains its own set of dimensions and measures. Joining: Combining the data between two or more tables or sheets within the same data source is data joining. All the combined tables or sheets contain a common set of dimensions and measures.

What are the two components to become a Data-Drive Organization?

Data Culture + Technology = Data-Drive Organization Empowered with Data Culture and the right technology, people can ask questions, challenge ideas, and use data—not just intuition—to make decisions. And everyone unites over a shared mission to improve their organization and themselves with the power of data.

Tell the difference between discrete and continuous

Discrete values are single points counted separately from a group of other issues. Ex: The number of states in a country is one example Continuous values let the user use values in a range that can be either finite or infinite Ex: How a company's stock price changes

What do "live" and "extract" mean in Tableau?

Extract is a snapshot of the data set up so it can be added up. Extracts are loaded into the system, which makes Tableau run better. Whereas extracts won't help when data is constantly updated because we have to manually refresh the data for each change, a Live connection might slow down the processing. Still, it will update the data source itself. So, you should only use a live connection when data is constantly being changed. --Otherwise, you should use an extract file.

Give an overview of a Fact and a Dimension of the table?

Facts are numeric measures of data. They are stored in fact tables. Fact tables store that type of data that will be analyzed by dimension tables. Fact tables have foreign keys associating with dimensions tables. Dimension tables are descriptive attributes of data. Those will be stored in the dimension table. For example, customer's information like name, number, and email will be stored in the dimension table.

What viz you would used to show the duration of events or activities?

Gantt Chart

Is There a Difference Between Sets and Groups in Tableau?

Groups are one dimensional, used to create a higher level category by using lower-level category members. Sets can have conditions and can be grouped across multiple dimensions/measures. Example: A key difference here is that the groups will consist of the same customers even if their profits change later. While for sets, if the profit changes, the top five and bottom five customers will change accordingly.

Your supervisor is contemplating cutting store hours. She asks you to analyze the data and come up with ideas. How would you accomplish this task?

Heat maps are a great way to understand customer frequency and aggregation. She will be able to see which times aren't creating enough profits to justify staying open past a certain time. I would create the map and come up with times to reduce and close stores based on my analysis.

What are all of the different Filters in Tableau? (There's Six)

Highest to Lowest 1. Extract filters 2. Data source filters 3. Context filters 4. Filters on dimensions 5. Filters on measures 6. Table calculation filter

How Do You Handle Null and Other Special Values?

If the field contains null values or if there are zeros or negative values on a logarithmic axis, Tableau cannot plot them. Tableau displays an indicator in the lower right corner of the view, and you can click the indicator and choose from the following options: Filter Data: Excludes the null values from the visualization using a filter. In that case, the null values are also excluded from any calculations used in the view. Show Data at Default Position: Shows the data at a default location on the axis.

What does bin mean in Tableau?

In Tableau, [...] are containers of the same size used to store data values that fit in the size of the bin. In other words, [...] divide the data into groups of the same size, which can be used to look at the data systematically. All of Tableau's discrete fields can be thought of as [...] instead.

Explain why data servers are essential in Tableau.

In Tableau, a data server has two jobs to do. 1. It lets you keep your data, like datasets, past calculations, aliases, and definitions, in sync with the server so that you can access it from anywhere. This makes it possible to do any task more honestly. So, it gives you security and quick access. 2. If you have a data server, you can download some of the data you need to a local machine to run a visualization or report. Through the server, it is easy to get from the internet.

Define LOD expressions and state the different types

LOD stands for level of detail. This means that you can do complex calculations at the data source level without bringing the data into Tableau. You can determine the level of granularity by creating INCLUDE, EXCLUDE or FIXED LOD expressions. INCLUDE LOD calculates with more granularity, EXCLUDE LOD has less granularity, and FIXED LOD calculates independently of any other dimensions.

Who is Salesforces CEO?

Marc Benioff

What do Measures and Dimensions mean?

Measures and Dimensions are parts of a Tableau dataset that describe it. Measures are amounts of data that can be counted and analyzed against dimensions. Dimensions determine how many measures can be added to a single string. For example, an online shop's inventory can list the number of items, their prices, the number of things sold in the past, how they are paid for, etc. All of these can be thought of as steps. On the other hand, dimensions are just descriptions that make it possible to see something. They let a user say different things about a single metric. All of these descriptions make up a dimension table.

What are the three performance optimizations to keep in mind for Tableau Server?

Optimize for User Traffic: This tunes the server to respond to user requests and to display views quickly Optimize for Extracts: This tunes the server to refresh extracts for published data sources. You might want to optimize for extract refreshes if your organization has a lot of data and the data needs to be as up-to-date as possible. Optimize for Query Heavy Environments: This is a specialized server configuration to optimize for query performance of workbooks that use extracts as their data source

How are joins and blends used in Tableau?

Same data sources can be JOINed Different data sources can be blended

What's the Tableau Treemap Description?

Showing hierarchical data as a proportion of a whole. Ex: Storage usage across computer machines, managing the number and priority of technical support cases, comparing fiscal budgets between years.

What is TabJolt?

TabJolt is a load-testing tool that lets users execute interactions and collect key metrics, such as response time and throughput. It works with Tableau Server 9.0 or later. It can automatically interpret test data on Tableau Server and should be used when doing go-live testing on the server or during server upgrades or deployments.

What is Tableau Data Engine?

Tableau Data Engine is a really cool feature in Tableau. Its an analytical database designed to achieve instant query response, predictive performance, integrate seamlessly into existing data infrastructure and is not limited to load entire data sets into memory. It's also called 'Hyper' If you work with a large amount of data, it does takes some time to import, create indexes and sort data but after that everything speeds up. Tableau Data Engine is not really in-memory technology. The data is stored in disk after it is imported and the RAM is hardly utilized.

What is the Difference Between a Live Connection and an Extract?

Tableau Data Extracts are snapshots of data optimized for aggregation and loaded into system memory to be quickly recalled for visualization. Ex: Hospitals that monitor incoming patient data need to make real-time decisions. Live connections offer the convenience of real-time updates, with any changes in the data source reflected in Tableau. Ex: Hospitals need to monitor the patient's weekly or monthly trends that require data extracts.

What Are the Filters?

Tableau [...] are a way of restricting the content of the data that may enter a Tableau workbook, dashboard, or view.

In Tableau, what is analysis?

Tableau has built-in tools to help you analyse the data on a chart. We have several tools, such as adding an average line to a chart. Once we drop the tool on the chart, Tableau does the math. There are also tools to explore and inspect data, such as clustering, percentages, making bands of a specific size, and more. These tools can be found on the "Analyze" tab of every sheet used to create a chart. The features only show up when they can be used on the worksheet.

What is Tableau?

Tableau is a powerful data visualization tool that allows users to connect to various data sources, create interactive dashboards, and generate insightful reports. Tableau is the Business Intelligence (BI) industry's most potent and fastest tool for visualising data. It turns the raw data into a format that is easy to understand. Tableau makes it faster to look at the data. Dashboards can be used to create visualisations.

Explain the Difference Between Tableau Worksheet, Dashboard, Story, and Workbook?

Tableau uses a workbook and sheet file structure, much like Microsoft Excel. - A Workbook: contains sheets, which can be a worksheet, dashboard, or a story. - A Worksheet: contains a single view along with shelves, legends, and the Data pane. - A Dashboard is a collection of views from multiple worksheets. - A Story contains a sequence of worksheets or dashboards that work together to convey information.

What are the Rank Functions in Tableau? (There Four of Them)

The ranking is assigning something a position usually within a category and based on a measure. Tableau can rank in several ways like: 1. Rank(): Assigns a whole number rank starting with 1, in ascending or descending order to each row. If rows have the same value, they share the rank that is assigned to the first instance of the value. 2. Rank_dense(): Assigns a whole number rank starting with 1 in ascending or descending order to each row. If rows have the same value, they share the rank that is assigned to the first instance of the value, but no rank values are skipped so you will see consecutive rank values. 3. Rank_modified(): Assigns a whole number rank starting with 1, in ascending or descending order to each row. If rows have the same value, they share the rank that is assigned to the last instance of the value 4. Rank_unique: ???

What's the difference between slowly ever-changing and junk dimensions?

The slowly ever-changing dimension means that there's a slow change over time. Ex: include geography and customer dimensions Junk dimensions are where analysts store unwanted or unrelated data so the data is clean and free from too many foreign keys.

Name and describe the Tableau Server components.

There are four Tableau Server components. (1) The application server manages the authentication and authorization of users and other interfaces. (2) VizQL Server handles automatically converting data source queries into visualizations. (3) Gateway provides the conduit for user requests to Tableau's components, and (4) Clients are all about viewing and editing visualizations on different clients, such as Tableau desktop and mobile apps.

How can I make Tableau work better? (There's Seven Of Them)

There are many ways to improve performance, 1. Use an Extract to make workbooks run faster 2. Reduce the scope of data to decrease the volume of data 3. Reduce the number of marks on the view to avoid information overload 4. Hide unused fields 5. Use Context Filters 6. Use Indexing in tables and use the same fields for filtering 7. Remove unnecessary calculations and sheets When in doubt, reference the performance recorder

How Can You Optimize the Performance of a Dashboard?

There are multiple ways to optimize the performance of the dashboard like: - Maximize the number of fields and records. You can exclude unused fields from your visualization or use extract filters. - Limit the number of filters used, by avoiding quick filters and using action and parameter filters instead. These filters reduce query loads. - use Min/Max instead of Average because average functions require more processing time than Min/Max - Use boolean or numerical calculations more than string calculations. Computers can process integers and boolean much faster than strings.

With a Creator License I can...

This can include the design, cleaning, and curation of data sources, which others will use to analyze governed data, or the creation of visualizations and dashboards with which other users will interact.

How can you create a dashboard in Tableau?

This is the final step in creating the visualisation. First, make all of the charts in separate sheets. Then, click "add new dashboard" in the tab where you add new worksheets. You can also right-click on the "Add new sheet" button and choose "Add new dashboard" instead of "sheet." To create a new dashboard differently, click Dashboard in the toolbar. Once you've done one of those three things, you'll be brought to a new dashboard where you can begin piecing together your story by dragging the relevant sheets from the left panel onto the dashboard individually.

What's a fun fact about Sets?

We can't use Groups in calculated fields, but we can use Sets.

What viz you would used to show aggregated sales totals across a range of product categories and subcategories?

Treemap

How does custom SQL work in Tableau?

Users can get the information they need with the help of a custom SQL. You can write your own SQL query when you connect Tableau to a data source. Once you're connected to a data source, on the data source page, double-click the "New Custom SQL" option. Then type the SQL query or copy and paste it into the text box, and when you're done, click OK.

What is VizQL?

VizQL stands for visual query language for databases. It's the proprietary formal language within Tableau that enables the tool to natively understand interactive data visualization. It's the centralized location for different types of visualization tools, making it easy for the application to switch between representations. It's also used to develop custom tools for specific applications

What Would You Do If Some Countries/Provinces (Any Geographical Entity) are Missing and Displaying a Null When You Use Map View?

When working with maps and geographical fields, unknown or ambiguous locations are identified by the indicator in the lower right corner of the view. Click the indicator and choose from the following options: 1. Edit Locations - correct the locations by mapping your data to known locations 2. Filter Data - exclude the unknown locations from the view using a filter. The locations will not be included in calculations 3. Show Data at Default Position - show the values at the default position of (0, 0) on the map.

What are two fun facts around data Extracts?

When you create an extract of the data, Tableau doesn't need access to the database to build the visualization, so processing is faster. If you have a Tableau server, the extract option can be set to a refresh schedule to be updated.

In Tableau, what is the Quick Filter?

When you use a filter in Tableau, you can easily change how it works. Ex: you can use it as a single-value drop-down list, a single-value list, a multiple-value list, a multiple-value drop-down list, or something else. After we add a filter to a sheet, we can right-click on the sheet to see all the quick filter options. If you change any of these options, the way the filter looks on the sheet will also change.

Explain the limitation of context filters in Tableau?

Whenever we set a context filter, Tableau generates a temp table that needs to refresh each and every time, whenever the view is triggered. So, if the context filter is changed in the database, it needs to recompute the temp table, so the performance will be decreased.

How do I display an axis in Tableau?

You can choose whether to show or hide an axis. To hide the axis, right-click on the axis and uncheck "Show header." To bring back the hidden axis, right-click on the fields in a row or column and choose "show header."

What are cycle fields in Tableau used for?

[...] let you try and switch between different color combinations or views in a loop. It will only work if we have a chart showing more than one measure, like a stacked bar chart, and we can't finish the visualizations. In that case, we can use [...]. To use the [...], go to the toolbar and click on the analysis menu. Then, click on [...] to quickly look at a different way to display the data.

What is the Use of Dual-axis? How Do You Create One?

[...] allows you to compare measures, and this is useful when you want to compare two measures that have different scales. Scenario: We want to show Sales by year and Profit Ratio by year in the same view.

How do I make Sets in Tableau?

[...] are custom fields that let you compare and ask questions about a subset of data. To make a set on a dimension, right-click on a size in the data pane and choose to create > set. On the "General" tab, select the fields used to figure out the set. On the conditions tab, you can set the conditions for making a set. On the top tab, you can also choose the top N members of the dataset based on any field. When a set is made, the measure is split into two parts, "in" and "out" of the set, based on the user's conditions.

In Tableau, what is a Context filter?

[...] can improve the dashboard's view when more than one filter is used. A filter in Tableau works on every row in the dataset, no matter what other filters are in place. By utilizing a [...], we can cut down on the size of the dataset. The rest of the filters will then be run on the smaller dataset, reducing the time it takes.

What is a cascading filter?

[...] filters can also be thought of as giving priority to one filter and then using other filters on a data source that has already been filtered. Right-click on the filter you want to use as the primary filter and ensure it is set to "all values" in the dashboard. Then, select the following filter and choose only the relevant values to cascade the filters. This will improve the dashboard because you have reduced the time wasted running all of the filters over the whole data source.

With an Explore License I can...

[...] have the freedom to access and analyze published data, create and distribute their own dashboards, and manage the content they have built or been granted permission to edit. You have access to a subset of Tableau Creator capabilities specifically via Tableau Server or Tableau Cloud for authoring new content based on existing published data sources and workbooks.

What is the Tableau Desktop?

[...] is a product made by Tableau that is used to create, edit, and store data visualizations locally on a system. You can publish the visualizations to a server, online, or to the public after they are done or maybe even in the middle of the process. [...] users can also edit any file made on another system in the same or a lower version of Tableau.

Explain The Tableau Blueprint

[...] is a step-by-step guide to becoming a data-driven organization, whether your organization is new to modern, self-service analytics or you've already deployed and need to broaden, deepen, and scale the use of data.

What does it mean to data visualization?

[...] is the process of showing data or information visually. We can use graphs, charts, bars, and many more things that are easy to see. Data visualisation tools make it easy to look at and understand the data.

What Do You Understand the Blended Axis?

[...] is used to blend two measures that share an axis when they have the same scale. Scenario: Show Min and Max profit in the same pane and have a unified axis for both, so that it is quicker and easier to interpret the chart.

What is a Tableau Server?

[...] is used to organize, edit, share, and work together on Tableau dashboards made on the Tableau desktop. It's safer for organizations because the data will only be seen by people who work there, and the administrator can decide how much control each user has. Ex: a user might only be able to view the data, or only be able to edit it, or both.
