Multiple database connections are also available in a single Codeigniter programme. All we have to do now is add the database configuration array to the database. Then, with the help of "$this->load->database('another db', TRUE);," we can easily load specified database data.
CodeIgniter includes a full-featured, lightning-fast abstracted database class that supports both traditional and Active Record database structures. The database functions have a straightforward, easy-to-understand syntax.
You can save your database connection values in CodeIgniter's config file (username, password, database name, etc.). The database configuration file may be found in application/config/database.php. By putting database, you may also set database connection values for certain contexts.

Hooks in CodeIgniter allow you to access and modify the framework's inner workings without having to edit the core files. When you execute CodeIgniter, it follows a precise execution procedure that is depicted on the Application Flow page.
