# Create a Table in the Data Store

Let's now create a table in the Data Store of the **Dialer** project. As discussed earlier, this table is used to store to-do list items created by the user.

To create a table:

   1. Navigate to **Cloud Scale** in the Catalyst console and click **Start Exploring**.

   2. Navigate to **Data Store** on the left pane and click **Create a new Table**.

   3. Enter the table's name as "**CallLog**" 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 and displayed in the Data Store page.

### Create Columns

Next, let's create a column to store the details of the call.

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

   2. Enter the column's name as "**callDuration**". Select the data type as **'int'** and click **Create**.

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

The column will be created and listed in the Schema View section.

You must now create five other columns in the same way. The table must contain six columns in total with the following mandatory properties :

<table class="content-table">
<thead>
<tr>
<th>Column Name</th>
<th>Data Type</th>
<th>Max Length</th>
</tr>
</thead>
<tbody>
<tr>
<td>callStatus</td>
<td>varchar</td>
<td>255</td>
</tr>
<tr>
<td>calledCountry</td>
<td>varchar</td>
<td>255</td>
</tr>
<tr>
<td>timeOfCall</td>
<td>varchar</td>
<td>255</td>
</tr>
<tr>
<td>fromNumber</td>
<td>varchar</td>
<td>255</td>
</tr>
<tr>
<td>toNumber</td>
<td>text</td>
<td></td>
</tr>
</tbody>
</table>

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

You have now configured all the necessary components from the console. You will now be working on coding the application from your local system.
