There is not much difference for a developer in EAV and Flat collections. The creation of models, resource models and collections is very similar. Let’s describe the key differences between EAV and flat table collections and consider creating classes for EAV (City) and Flat (Country). This is Part 2 of the EAV data storage review, check out Part 1 to catch up on the topic.
Magento 2 Development
Magento 2 allows you to perform multiple operations using the command line interface (CLI) and contains a large number of commands that allow you to quickly clear the cache, change the deployment mode, or reindex the required index.
Magento 2 Plugin (Interceptor) is a class that allows you to change the behavior of other classes’ methods by calling custom code before, after, or instead of calling specific methods. This reduces the probability of conflicts between different code sections representing the same functionality.
Default Magento 2 functionality allows only logged-in visitors to create and save their wish lists. However, popping register/login windows usually irritate users and make them leave the website. The BelVG team has developed the Guest Wish List extension for guest users to be able to add items to their wish lists equally with registered customers.
