== Some Basic Rules ==

'''Exception Handling'''

# All functions of libaries and models should fire an exception if something goes wrong. Do not return "false" or something similar to represent an error.
# All database-queries should be executed via "dbquery($query)". This helper-function provides a pattern for database queries including a correct exception handling. Read more here: [[Helper: dbquery]]

== Extended Core ==

* [[Extended Core: Exceptions|Exceptions]]:<br />Here you can tell CodeIgniter to throw real exceptions.

== Helper ==

* [[Helper: dbquery|dbquery]]:<br />Pattern for database queries.

== Abstract Models ==

Abstract model classes are implemented as codeigniter-helper. There is no other way to use the codeigniter-loader without to be forced to instatiate a class.

== Model ==

* [[Model: Tree|Tree]]:<br>Abstract class to build a model interacting with a table representing data in a hierachical structure.
