• A .twb extension is an XML document that includes all the selections and structure you have made in your Tableau workbook.
• A .twbx extension is a ‘zipped’ archive including a .twb and any outer files like background images and extracts.

It is really an interesting feature in Tableau. Tableau Data Engine is an analytical database designed to gain instant query response, integrate seamlessly, predict performance into present data infrastructure, and is not restricted to loading whole data sets into memory.

If you operate with a big amount of data, it takes some time to import, sort data, and create indexes but after that everything speeds up. It is not an in-memory technology and the data is preserved in disk after it is imported and the RAM is severely utilized.

• Normal Filter: It helps in restricting the data from the database which is based on the chosen dimension or measurement. A Traditional Filter can be made by just dragging a field onto the ‘Filters’ shelf.
• Quick filter: It helps in viewing the filter option and filtering each worksheet on a dashboard while modifying the values dynamically (within the range specified) during the run time.
• Context Filter: It helps in filtering the information that is assigned to each worksheet. When a worksheet queries the information source, it makes a temporary, flat table that is used to calculate the chart. This provisional table contains all values that are not filtered out by Custom Filter or the Context SQL.

• Tap the drop-down to the right of Measurements on the Data pane and choose “Create > Calculated Field” to open the calculation editor.
• Name the new field and make a formula.

A heat map is utilized for comparing varieties with size and color. By using heat maps, you can compare two separate measures together.

A treemap is the same except one as treemap is known as a very effective visualization as it can help in illustrating hierarchical data and part-to-whole connections.

In Tableau, SQL Queries gives two options:

• Make a Performance Recording to document performance data regarding the main events you interact with within the workbook. Users can view the performance analytics in a workbook designed by Tableau.
  Help -> Settings and Performance -> Start Performance Recording
  Help -> Setting and Performance -> Stop Performance Recording.

• Reviewing the Tableau Desktop Logs situated at C:UsersMy DocumentsMy Tableau Repository. For live relation to an information source, you can uselog.txt and tabprotosrv.txt files. For an extract, review tdeserver.txt file.

It is a Tableau desktop file that includes a .tde extension. It directs to the file that includes data extracted from outer sources like MS Excel, CSV file, or MS Access.

Two parts of TDE design-construct them for keeping analytics and data discovery.

• Firstly, TDE is a columnar store.
• The second is how they are structured which affects how they are loaded into memory which is further used by Tableau. It is one of the essential aspects of how TDEs are “architecture aware”. Architecture-awareness represents that TDEs use complete computer memory, from RAM to hard disk.

In some circumstances, you can enhance query performance by choosing the option to Assume Referential Integrity from the Data menu. By using this option, Tableau will contain the joined table in the query only if it is expressly referenced by fields in the view.

23.

• Discrete data functions are values that are calculated as distinct and different and can only take particular values within a range. Examples: customer name or row ID or State and number of threads in a sheet.
• Continuous data functions are utilized to calculate continuous data and can take on any value within a limited or unlimited interval. Examples: unit price, profit, time, or order quantity.

• Hit the New Story tab.
• In the lower-left corner of the display, select a length for your story. Choose from one of the predefined sizes, or specify a custom size, in pixels.
• Your story gets its name from its sheet name as a default setting. So, to change it, double-click the name and modify it as per your preference. You can also modify your title’s alignment, color, and font. Press Apply to view your modifications.
• To begin building your story, drag a sheet from the Story tab from the left and leave it in the middle of the view
• Hit Add a caption to rephrase the story point.
• To highlight a key for the users, drag a textbox object over to the story worksheet and write your writings.
• To highlight the central idea of this story, you can modify a filter or category on a field in the view, and then preserve your modifications by pressing the Update option provided above the navigator box.

• Using groups in a calculation: You are not able to reference ad-hoc groups in a calculation.
• Blend data utilizing groups formed in the secondary data source: Only calculated groups can be utilized in data blending if the group was formed in the secondary data source.
• Use a group in another workbook: You can smoothly duplicate a group in a different workbook by copying and pasting a calculation.

• Published data source: It includes contact information that is freed from any workbook and can be utilized by numerous workbooks.
• Embedded data source: It includes contact information and is connected with a workbook.

• Workbooks: It keeps one or more worksheets and dashboards
• Bookmarks: It includes one worksheet and it’s an effortless way to speedy share your work
• Packaged Workbooks: It includes a workbook along with any supporting local file data and background images
• Data Extraction Files: Extract files are a local copy of a subset of full data source
• Data Connection Files: It’s a small XML file with different connection data.

According to your question, you must have city, state, sales, profit fields in your dataset.

Step 1: Double click on the state field

Step 2: Pull the city and drop it into Mark’s card.

Step 3: Drag the sales and leave them into size.

Step 4: Drag profit and leave it into color.

Step 5: Click on the size legend and improve the size.

Step 6: Right-click on the state field and choose show quick filter.

Step 7: Choose any state now and review the view.
