/**
 * Class Model
 *
 * Models provide an easy connection to database tables. Each table requires its own model. You don't need to worry about your queries or syntax anymore, because
 * models will handle queries and error handling. Because of this, you can freely change your database infrastructure without fear of needing to change your
 * table names at thousands of places. The model is the only place where you have to change your database names or fields.
 *
 * Models also allow custom methods to be created on them. You can use those methods to create specific operations or joins and then use the newly created method
 * everywhere in your project. The code is at one place, the usages all over your project. Isn't that great?
