 ### Creating the table database model and response model
 
 
 The model must extend from the `DatabaseModel` class, this class will handle the representation of the model as a table in the database.
 
-Every table field is indicated with the annotation `@DbField` taking the field name from the anottation `@SerializedName`, and the table primary key should be explicited with `@DbPrimaryKey` ( the PK should be any integer type ). The primary key value should be the id of the object provided by the server. In this case we don't have a primary key so that field it's not declared.
-`@SerializedName` is also used to convert the json object from the rest api call response to a java object.
