database

This package contains everything that concerns the database of the application, we have:

• DatabaseConnection.java that's responsible for getting the environment variables needed to connect to the database we are using and performing it;
• DbModel.java which has methods responsible for instantiating each class of the model, receiving the connection and a ResultSet from which comes the data needed to instantiate the specific class.
• a sub-package named data which contains a class for each entity in our model with the queries we thought necessary to access our database.
