New catalog
===========

Let's go back to the Application builder page and create a "Customers" catalog.
A catalog corresponds to a new table in the database.

To do this, select the "Catalogs" group in the project tree and click the **New**
button on the bottom right corner of the page

	:alt: Catalogs

In the 
:doc:`Item Editor </admin/items/item_editor_dialog>`
dialog that appears, fill in the caption and name of the new catalog. The caption
is the name that will be displayed to users, and the name is the variable name that
will be used in code (Python or JS) to refer to this catalog. The name must be a
valid Python identifier.

Then, click the **New** button on the bottom right corner of the dialog to add a new field. The
:doc:`Field Editor </admin/items/field_editor_dialog>`
dialog appears. Type the caption and name of the 
"Firstname" field, select its type (here ``TEXT`` with 30 characters)
and click the **OK** button.

Similarly, add the "Lastname" and "Phone" fields. When adding the "Lastname"
field, check the **Required** attribute. This requires that the field is set
when creating a new item.

Now, to save the changes, click the **OK** button. When saving, the Application 
builder created the ``CRM_CUSTOMERS`` table in the ``ctm.sqlite`` database:

Go to the Project page and make sure it is refreshed

.. code-block:: console

    127.0.0.1:8080



Then, click the **New** button to create a new customer.
Fill in the dialog, then click the **OK** button:
