To model your use case and optimize ThoughtSpot Search, create a Worksheet.

Whenever you start a new analytics inquiry, the most important question to ask is “What use case does this support?”

We recommend that you keep the following points in mind as you select your use case, and then design a Worksheet to support it.

Good use cases support:

  • Actionable data, and measurable value
  • Time value of answers
  • Variability of questions
  • Large addressable audience
  • Large data volume, and need for granular analysis at variable levels
  • Relational data that is modeled for analytical use

Worksheets provide a simplified view of your data for users to search. We designed them to directly support use cases, so they have the following advantages when compared to searching directly across tables:

  • Optimize the Search experience
  • Present only relevant data columns, to reduce information overload
  • View flat presentation of combined data tables
  • Rename columns and terms
  • Enable change of numerical columns from measurement (default) to attribute
  • Specify default aggregation functions
  • Specify formatting and currency symbols
  • Identify columns that contain geographical data
  • Match the user vocabulary by mapping data to recognizable business concepts
  • Standardize formulas for consistency and governance

Create Worksheets

 

Follow these steps to create Worksheets:

Create a Worksheet

  1. Under Data, see Sources. Click +.

  2. The Choose sources interface appears.

    It contains the list of tables that in the connection.

  3. Click on each table you plan to include in the Worksheet.

  4. At the top right corner of the interface, click Close.

  5. Back on the Data interface, under Sources, note that the list of tables you selected appears.

  6. Expand one of the tables by clicking the toggle icon.

  7. Select the columns to include in the Worksheet.

  8. Click + Add columns.

  9. Notice that the table and its columns appear on the main pane of the interface.

  10. Repeat for each table you plan to include in the worksheet.

    You can always navigate to a table you identified, and change the column selections.

  11. After you finish selecting the tables and columns, click the More menu at the top right corner of the interface.

    Click Save.

  12. In the Save Worksheet interface, enter the following values:

    • Name is the name of the Worksheet. You can select it as a data source in your searches.

    • Description is optional; we recommend that you identify the supported use case here.

    Click Save.

  13. Congratulations! You now have a Worksheet to use as a data source for Searching and building standard formulas.

    We recommend that you customize the worksheet in the following manner:

    • Rename columns to make them user-readable.
    • Change column type default settings of numeric fields from measurement to attribute, when these numbers represent categorical information instead of measurements that are aggregated.
    • Change aggregation function for measurement columns. For example, columns that track life expectancy should use AVERAGE or MAX, and never use SUM.

Next, you can proceed to Visualize Search results as Answers.
