# Eagle Estates - Part 11

Having a grasp of Magic Numbers and Commands gives us a good understanding of data can be set for One2many and Many2many fields, to further understand this, let's apply the following changes to our module:

Let's create some data that will be used alongside our app:

# Tags:

Add a new eagle_tag_data.xml file in the data folder, that will define tags with the following names:

  • Residential
  • Commercial

# Properties:

Add a new eagle_property_data.xml file in the data folder, that will define properties with the following data:

  • Property 1 (Apartment 217)
    • Name: "Apartment 217"
    • Construction Date: 2009-10-01
  • Property 2 (Apartment 9905)
    • Name: "Apartment 9905"
    • Construction Date: 2010-04-24
  • Property 3 (Burj Khalifa)

      • Zip: "00000"
      • City: "Dubai"
