# Create a Table

Let’s now create a table in the Data Store of the **AlienCity** project. This table is used to store records of city names where aliens were sighted.

To create a table:

1. Navigate to the *Cloud Scale* section of the console, then click **Start Exploring**.

2. Navigate to **Data Store** under *Storage* and click **Create a New Table**.

3. Enter the table’s name as "**AlienCity**" and click **Create**.

> **Note:** Ensure that you enter the name exactly as instructed, because the application's code contains the same name.

The table is now created.

Next, let’s create a column in the table to store the names of the cities.

1. Click **New Column** in the *Schema View* section for the table.

2. Enter the column’s name as "**CityName**". Select the data type as **Var Char** and enter the max length as "**100**". Click the **Is Unique** toggle switch to enable it.

> **Note:** Ensure that you enter the name exactly as instructed, because the application's code contains the same name.

You can learn about the various data types supported by Catalyst, as well as the other properties of a column, from the [Data Store help page](https://docs.catalyst.zoho.com/en/cloud-scale/help/data-store/columns/).

3. Click **Create**.

The column is now created and listed in the *Schema View* section.
