* @return string the Data Source Name, or DSN, contains the information required to connect to the database.
* Please refer to the [PHP manual](http://php.net/manual/en/pdo.construct.php) on the format of the DSN string.
*
* The `driver` array key is used as the driver prefix of the DSN, all further key-value pairs are rendered as
* `key=value` and concatenated by `;`. For example:
* ```php
* $dsn = new MssqlDsn('sqlsrv', 'localhost', 'yiitest', '1433');
* $connection = new MssqlConnection($this->cache, $this->logger, $this->profiler, $dsn->asString());
* ```
* Will result in the DSN string `sqlsrv:Server=localhost,1433;Database=yiitest`.
