57 Clase que modela la conexion con el RDBMS MySQL (tm).
59 Esta clase no puede usarse directamente, ya que la capa ANNA.dbms obliga a que todas las peticiones
60 se hagan atraves de una instancia anna::dbms::Connection.
62 Para obtener una conexion a una determinada base de datos habra que instanciar dicha base de datos
63 e invocar al metodo createConnection. Independientemente del tipo de conexion particular que la
64 base de datos retorne, debemos asignarlo a un puntero de tipo anna::dbms::Connection.
66 class Connection : public dbms::Connection {
69 Devuelve una cadena con la informacion referente a esta instancia.
70 @return Una cadena con la informacion referente a esta instancia.
72 std::string asString() const throw();
75 Operador de conversion.
76 \return El puntero al entorno asociado a esta base de datos.
