The Magento software is extremely useful and is one of the top ecommerce platforms available on the market. However, it does require a lot of space and memory. Furthermore, it requires object oriented programming in order to prevent turning into a very complex system. Finally, Magento can be slow in terms of performance, at times. However, these limitations are usually not a significant concern in most cases, and the benefits provided by the Magento Software usually far outweigh any potential issues.

8. How do you create a custom module in Magento?

In order to create a custom module in Magento, you must first - create a module directory, second – create controller, block, and module files for your module, third – create a module configuration file, and finally, fourth – create an XML file. The purpose of creating an XML file is so that you can enable or disable the module and also instruct the system which code pool that the module will be taken from.

Model View Controller design Pattern is used to keep the code modular and clean to assist in programming (keep things separate).

It divides a given software application into three interconnected parts, so as to separate internal representations of information from the ways that information is presented to or accepted from the user.
The central component, the model, consists of application data, business rules, logic and functions
A view can be any output representation of information, such as a chart or a diagram
Multiple views of the same information are possible, such as a bar chart for management and a tabular view for accountants.
The third part, the controller, accepts input and converts it to commands for the model or view.

The performance increase is between 25%-50% on page loads. In order to use this tool, the directory ‘includes’ and the file includes/config.php must both be writable.

9. What are the differences between EAV and Flat model?

EAV is an entity attribute value database model, where data is fully in normalized form. Each column data value is stored in their respective data type table. Example, for a product, product ID is stored in catalog_product_entity_int table, product name in catalog_product_entity_varchar, product price in catalog_product_entity_decimal, product created date in catalog_product_entity_datetime and product description in catalog_product_entity_text table. EAV is complex as it joins 5-6 tables even if you want to get just one product’s details. Columns are called attributes in EAV.

The flat model uses just one table, so it’s not normalized and uses more database space. It clears the EAV overhead, but not good for dynamic requirements where you may have to add more columns in database table in future. It’s good when comes to performance, as it will only require one query to load whole product instead of joining 5-6 tables to get just one product’s details. Columns are called fields in flat model.

10. What is the difference between “pay” and “capture” operations in Magento?
