The world is going through a technological boom with every sector is going towards modernization. The basic reason behind this boom is the resurgence of software. Software plays so many roles in our lives and in some ways we are addicted to the use of software whether knowing or unknowing way. The phones which we use are based on software similarly laptops, computers and other devices are all based on software.
With the increase in demand for software their raise a situation of developing more and more software so that its demands can be met. However, software development isn’t the cakewalk as it needs many steps and complete infrastructure which all can’t afford thus the need for software consultant occurs.
In simple term software consulting is the method by which a company contacts the software developing company to develop software for them. This software consulting company can be hired for a particular task or for the multi-task for a specific time. Consulting services can include from just developing software to provide after sales services also.
When Is Software consulting needed?
Basically, all the organizations depend upon software whether they are required for accountancy, security, web development and etc. depending upon the need of the company. Software consultant comes into play when new or a running company desire for software but they don’t want to invest in all the basic requirements such as computer sets, programming tools etc. which can be useless for the company once they get their software. By software consulting, they save their money making this method to be cost effective.
Software consulting assist the organization in so many ways, following are some main points:
Cost Effective: Software consulting services are generally cost effective in so many ways as we don’t need to locate and hire software developer directly. Secondly, the organization doesn’t have to buy all the technical programming tools which are required to develop software as they become useless after they get their software.
Expert opinion: Getting software consulting is like having an expert opinion as you can contact different software consulting companies at the same time and select the one which suits you more. By this, you can have the knowledge of how to go about the job as in case if you hire a developer you are bound to go by their way without any intervention.
Genuineness: With a good software consulting company you can rest be assured that the software provided to you is genuine in every nature as it becomes vague when you ask any free-lance developer to develop software for your company. The company can be held accountable in any flaw whereas it will be difficult to find and bring the free-lance developer to rectify the problem.
Services: The work of software needs to be updated and upgraded with the passing of time and it’s easier to the contact company to provide their service for updating rather than searching for the free-lance developer who might have changed his contact details over the period of time making it difficult for other developers to update the software.

Magneto development services provider will explain plugin system in Magento 2. You will learn the way to use magento 2 plugins from the basics. Read and discover how professionals do it.
You will learn through this article how to use Magento 2 plugins that modify the behavior of all public functions without overloading the PHP class (block, model etc.) the container.
What are plugins?
To avoid having to override a class to modify a simple, Magento 2 plugins provides a mechanism to effectively manage this type of "rewriting" as well as to minimize conflicts between extensions.
To date, plugins can only be used for rewriting public methods and are therefore subject to the following limitations:
1) final methods
2) non-public methods (protected or private)
3) static methods
4) Constructor ( _construct)
5) virtual Types
Magento provides three "types" of different plugins:
1) before: Change the arguments provided to a method
2) around: Change the behavior of a method
3) after: To "rework" the output of a method
Declaration of a plugin
The declaration of any plugin must be done in the file di.xml of your module. This file can be placed, depending on its use, either within the directory etcyour module (plugin to use the backend and frontend) or in etc/frontend
The following can be specified:
1) observer_type: The class name, or virtual interface type you want to observe
2) plugin_name: The name of the plugin (eg. catalog_product_custom_plugin)
3) plugin_type: The name of the class or type used by the virtual module (ex.Vendor\Module\Plugin\ModelNamePlugin)
4) plugin_order: The order in which the plugin will run. Very useful to effectively manage the execution order of several plugins overloading the same method (see "Execution Order" below for details)
5) plugin_disabled: This parameter can be set trueif you want to disable the plugin
Execution order of the plugins
When multiple plugins rewriting the same method exist, the following order of performance will be followed by Magento:
1. The type of plugin beforethat has the highest priority (= the one with the least sortOrder)
2. The type of plugin aroundthat has the highest priority (= the one with the least sortOrder)
3. The other type of plugins beforebased on their priority (from smallest to largest sortOrder)
4. The other type of plugins aroundbased on their priority (from smallest to largest sortOrder)
5. The type of plugin afterthat has the lowest priority (= the one with the largest sortOrder)
6. The other type of plugins afterbased on their priority (largest to smallest sortOrder)
To change the settings passed to a function, it is necessary to create a methodbefore[methodName]in your plugin (which [methodName]corresponds to not the method you want to change, for example SetNamefor a method named setName).
The method created within your plugin parameter must take the class which includes the function you want to change and its various parameters. Example of method overloading setNameclass \Magento\Catalog\Model\Product:
In this example, the product name passed in the argument $namewill be automatically enclosed in parentheses.
As you have probably noticed, the type of plugins beforehave returned an array containing all the parameters of the function.
To change the behavior of a function, a method around[methodName]must be created within your plugin (which [methodName]corresponds to not the method you want to change, for exampleSavefor a method named save).
The method created within your plugin parameter must take the class which includes the function you want to change and a second type parameter \Closurecorresponding to the original method.
Example of method overloading saveclass \Magento\Catalog\Model\Product:
In this example, we execute line 9 will recover the original method and the return value. If it is defined, a third function, called here doSomething, will be executed.
Finally, we return line 13 returning the original method.
To change the return of a function, it is necessary to create a method after[methodName]in your plugin (which [methodName]corresponds to not the method you want to change, for exampleGetNamefor a method named getName).
The method created within your plugin parameter must take the class which includes the function you want to change and a variable $resultthat will contain the result of the original method.
Example of method overloading getNameclass \Magento\Catalog\Model\Product:
In this example, the return of the original method, which is here in the name of the product, will be surrounded by "| ".
