Before we move on to data stores, we need to take a brief look at data formats. The three currently supported by Sencha Touch are Array, XML, and JSON. For each example, we will take a look at how the data would appear for a simple
contact model with three fields: an ID, a name, and an e-mail ID.
[ [1, 'David', 'firstname.lastname@example.org'], [2, 'Nancy', 'email@example.com'], [3, 'Henry', 'firstname.lastname@example.org'] ]
