    In application/config/database.php you place the settings to connect to your DB, for ex:

    $db['default']['hostname'] = '127.0.0.1';
$db['default']['username'] = '';
$db['default']['password'] = '';
$db['default']['database'] = '';
$db['default']['dbdriver'] = 'mysql';
//and so on...

    Then, you might want to autoload it to have always at hand and avoid calling the library often. You put it in the

    $autoload['libraries'] = array('database');

    which is on line 55 of application/config/autoload.php

    Then you can just call it in any controller or method (or custom libraries) with

    //$this->db->...  // method may vary

    look in User Guide on database driver for all details and methods and the useful Active Record (sortof), and if you’ve problem just ask.
