To create new module you must:

1. Create a folder in Addons

2. Create __init__.py

3. Create __openerp__.py

4. Create your module.py file

5. Create your module_view.xml file

6. Security folder and inside of this folder ir.model.access.csv where you can put some information about access etc

__init__.py should contain: import your_module/s_name/s

example:

# -*- coding: utf-8 -*-

import your_module_name

__openerp__.py should contain: a description of your module, dependencies, vews etc

example:

{

'name': 'Base',

'version': '1.3',

'category': 'Hidden',

'description': """

The kernel of OpenERP, needed for all installation.

your_module_view.xml should contain your_module_view_definition:

example:

<field name="model">res.groups</field>

<field name="inherit_id" ref="base.view_groups_form"/>

<field name="arch" type="xml">

</field>

<field name="name" position="after">

<field name="share"/>

</field>

</field>

</record>

</data>

</openerp>

your_module.py should contain:

#class with _columns will create your table with your columns

class your_class(osv.osv):

_name = 'your.class'#your new table

_description = 'Your class description'

_columns = {

'your_field_1': fields.type_of_field('Field name'),

'your_field_2': fields.type_of_field('Field name'),

'your_field_3': fields.type_of_field('Field name'),

'your_field_4': fields.type_of_field('Field name'),

}

    def your_def(self, cr, uid, args, fields, context=None):#check manual in case you need some special args o kwargs etc

        do something

Of course it's just a basics but .... that's all you need to build your own module. :)
