ThoughtSpot Tutorials for Snowflake Partner Connect

Explore these tutorials to learn how to model your data after connecting to your Snowflake database.

When you create a connection to Snowflake in ThoughtSpot, any data modeling or table joins are inherited automatically.

If there are no table joins in your Snowflake connection, you can easily create them in ThoughtSpot.

The following example shows how the table joins were created in the Sales table of the Retail Sales worksheet, available in your try.thoughtspot.com account created through Snowflake Partner Connect.

Searching joined tables

You can easily search the joined tables, without having to create a worksheet.

To search the joined tables, do the following:

  1. Click Search.

  2. Click the Retail Sales data source, and click Choose sources.

  3. Select all the tables you just joined (Customers, Dates, Products, Sales, and Stores) and click Close.

  4. In the search bar, enter sales_dollar_amount, store_region, and monthly Date in Dates.

    date in dates

    The search results look like this:

    When Monthly is a native keyword, it will work on any timestamp. For the purposes of this example, we’re using monthly as the date, from the Dates table.

  5. To confirm that the search is honoring the table joins, click the Query details icon query details icon, to the right of the chart.

Best practices for data modeling

Here are some examples of how you can model your data to enhance searchability:

  • Change column names

  • Add synonyms for columns

In the following example, the Sales_Dollar_Amount column was renamed to Sales and the synonyms of Revenue and Dollars were added.

These are just a couple of examples of things you can do.

Creating a worksheet

A Worksheet is a curated dataset built for ad-hoc analysis, that allows you to translate data from a database into the language of your business users.

Examples of things you can do in a Worksheet include:

  • Removing columns that aren’t needed

  • Adding data labels and synonyms

  • Adding calculations, such as margin

The worksheet based on the Sales table on try.thoughtspot.com was created by doing the following:

  1. Click Data.

  2. Click the more options icon more options menu icon, and select Create worksheet.

    worksheet create icon

  3. Click the + icon, next to Sources.

  4. Check the box next to all five of the tables from the Retail dataset in your schema.

  5. Make sure the default setting of Apply joins progressively is selected. This ensures that the search uses only the tables that are required.

  6. Click Close.

  7. In the Data view, click the name of the Customers table to reveal all of the columns in that table.

  8. Double-click each column from the Customers table that you want to include in the worksheet.

    Include these columns:

    • Customer_Type

    • Customer Name

    • Customer_Gender

    • Customer Region

    • Customer State

    • Customer City

    • Customer Zip Code

    • Customer County

  9. Use the same process to select columns from the other tables to include in the worksheet.

    From the Dates table, include this column:

    • Date

      From the Products table, include these columns:

    • Product_Description

    • Category_Description

    • Department_Description

      From the Sales table, include these columns:

    • Sales_Dollar_Amount

    • Cost_Dollar_Amount

    • Gross_Profit_Dollar_Amount

      From the Stores table, include these columns:

    • Store_Name

    • Store_Region

    • Store_State

    • Store_City

    • Store_Zip_Code

    • Store_County

    As a best practice, you would not select a key from a table when creating a worksheet, because you would not want to search for the key.

  10. Click the pencil icon edit icon next to the current name of your worksheet, enter the name Retail Sales, and click Done.

  11. Click the more options icon more options menu icon, and select Save.

    Now, let’s add a percent gross margin formula to the worksheet.

  12. Click Edit Worksheet.

      sum ( gross_profit_dollar_amount ) / sum ( sales_dollar_amount ) * 100

    3. Click Save.

  15. Save the worksheet with the formula added, by clicking the more options icon more options menu icon, and selecting Save.

  18. Save the Worksheet with the updated formula settings, by clicking the more options icon more options menu icon, and selecting Save.
