Headers

The DBManager library header has two different classes with their respective class methods, besides the auxiliar enumerator. Together they perform what has been promised.

  • DBData: Auxiliar class which helps to configure the database connection.
  • DBManager: Singleton class which manages a unique connection between the application and the database.
  • DBConnectionType: Enumerator which is used to specify the database driver that the application must use.
