First create a model (if you dont have one yet) then create some fields on this model:
_name = 'check.demo'
name = fields.Char(required=True)
numberOfUpdates = fields.Integer('Number of updates', help='The number of times the scheduler has run and updated this field')
lastModified = fields.Date('Last updated')
This will create a new model named check.demo which will contain three fields: a text field for the name, an integer field to keep track of how many times the record was updated and a date field.
This is all you need on the database level. You have your fields in the database, now you only need to show them to the user now.
