Architecture Concept

The entry and exit point of the whole framework is index.php file. This file includes the application configuration files to configure the settings, autoload files to include all the base classes and functions, and route files to call method of a controller class defined for the current URL. All of these are done within a try catch function, which reports error if any exception is found while performing an action.

The framework follows MVC (Model, View, Controller) pattern. How the general flow of activities follows this design pattern within this framework is explained below-

• Models are where all the classes based on the real life entities associated with the program, their relations, objects and methods are defined, and OOP (Object Oriented Programming) concept is applied on top of them. This is where different CRUD (create, retrieve, update, delete) actions are generally performed and passed to the Controller.

• Controllers retrieve data returned from model, perform necessary actions on them and pass it to the view. Generally, access control logic is applied here as well.

• Views are used to construct visual layout and present the data to the user.

Additionally, apart from working on models, views and controllers:

• Various base classes and functions from base folder (located in vendor/codecube directory) can be called to follow the standard way of accessing database, input validation, defining layouts, connecting models , controllers and views etc.

• Methods from helper classes, or classes included by composer dependency can be called to perform certain actions on the data anywhere within the system.

• Controller will call method from guard classes to implement access control logic.
