Any function that starts with two underscores (__) is known as the magic method. With magic methods, you can call any function automatically. There is no need to call functions explicitly to execute codes in these functions. You can call Magic methods to check, set, unset, and retrieve data.
The following is the list of magic methods in Magento:
|__construct()||This method is called automatically after the creation of an object.|
|__destruct()||This method is called when an object has no other references.|
|__get()||This method is called when we intend to get values for class properties.|
|__set()||This method is called when we intend to put values for class properties.|
|__call()||This method is called when an inaccessible or undefined method is called in an object.|
Google Checkout is the service offered by Google for making online payments. This way, Magento supports connecting online stores with Google Checkout to ease payment processing. Google Checkout is also known as Google Pay. For Google Pay, you can find a plug-in in the Magento Marketplace.

In Magento, the order lifecycle starts from a new order, pending payment, payment processing, invoicing the order, shipping the order, and completing the order finally. You can understand this by the following flowchart.
Magento's Order Management System (OMS) manages orders, inventory, selling products, and many more. It provides good visibility over all the inventory and shipping of products.

In Magento, handles help to identify a page in an application. Here, the handle name can be derived from the URL used to locate the layout files for the page.
For example, consider the URL 'view/frontend/layout/checkoutpaymentindex.xml'. In this URL, checkoutpaymentindex is the handle name, and the front-end is the area name.
A layout handle represents the name of a layout file. There are three types of layout handles, as given below:
The layout is the basic component in page design and defines the structure of a webpage. Containers are the placeholders on a web page. And blocks are the UI elements within the containers. By identifying the suitable containers and blocks, the XML file composes webpages in Magento. The below image will help you understand about page layout.
In Magento, CMS is a powerful tool that supports effectively managing webpages' content. CMS offers features such as CMS pages, CMS Widgets, and CMS blocks. Let’s see the use of each features one by one below:
Composer is a dependency management tool used to manage Magento components and their dependencies. Also, the composer allows downloading third-party dependencies. Know that Magento uses two commands: ‘composer install’ and ‘composer update’, to fetch dependencies and check updates. By running composer install, composer allows fetching all dependencies of a Magento project. By running composer update, the composer checks new updates. Besides, the composer reduces compatibility issues and extension conflicts significantly.
Magento 2 generates the following five types of reports.
Metapackage consists of a composer.json file that includes the list of components as well as their dependencies. When more than one package is used in the extensions of a Magento application, metapackage serves as a root package. Because of this, metapackage will handle these packages as a cohesive unit.
Origin Cloaking is the security feature used to protect resources in the Cloud from non-fastly traffic such as DDoS attacks. This feature ensures that all network traffic is going through the fastly Web Application Firewall (WAF) and with internal WAF in the load balancer.

When you add a new attribute in the flat model, a new column is inserted into the table. In contrast, a new row is added to the table in the EAV model.
In Magento 2, dependency injection represents a design pattern that supports declaring object A on its dependencies to object B. Being an external object, object B supplies dependencies to object A. In a way, dependency injection replaces the functionalities provided by Magento 1 in a Magento application.
Registry pattern is one of the features of Magento 2, which makes objects and data available in the public scope. So, any resource can use these objects and data. For instance, all the singleton patterns can be stored in the internal registry, which acts as the global-scoped container for data storage.
In this regard, the Mage::register function is used to register objects and data. In reverse, you can deregister data and objects using the mage::unregister function.
In Magento, code compilation includes the following features.
Generally, patches are the packages of core files used to overcome the security vulnerabilities of online applications.

In general, the composer file manages the dependencies and libraries of a Magento project and supports installing the libraries and dependencies in the vendor directory. This way, the composer.lock file is used to store version dependencies. These dependencies must satisfy the version constraints for every package in the dependency tree.
