To develop an Odoo app (module), you create a folder with a __manifest__.py file describing the module, Python files for business logic (in models/), XML files for views and menus (in views/), and access control CSV files (in security/).

Example:

__manifest__.py

{

  'name': 'My Module',

  'version': '1.0',

  'depends': ['base'],

  'data': ['security/ir.model.access.csv', 'views/my_model_views.xml'],

  'installable': True,

}

models/models.py

from odoo import models, fields

class MyModel(models.Model):

    _name = 'my.model'

    name = fields.Char(string='Name')

views/my_model_views.xml

<odoo>

  <record id="view_my_model_form" model="ir.ui.view">

    <field name="model">my.model</field>

    <field name="arch" type="xml">

      <form>

        <field name="name"/>

      </form>

    </field>

  </record>

</odoo>

This is the basic structure to get started with Odoo app development.
