Q: What Is Ruby On Rails, PHP, and MySQL?
One of the main positive and negative aspects associated with the technology that it is continuously changing, developing and getting better. On the positive side, new technology allows the users to carry out a good number of productive activities, expand the business and perform the work more efficiently.

So, if you have a web presence, then it is vital on your part to understand these different terms and services.
Ruby On Rails
Ruby on Rails, largely familiar as Rails or just RoR, is a framework for developing web application. This popular framework is written in Ruby Language and is mainly developed in order to make the programming of web applications much easier. This framework makes assumptions as regards to the needs and requirements of every web developer at the initial levels. It enables the developers to write only a few codes while performing bigger tasks as against many other frameworks and their related languages.
Rails is more of an opinionated software application than a mere framework. It makes use of an assumption that there is always a best method to perform various tasks. Rails is mainly designed to support that particular method of carrying out things. If you are able to master the Rails Way, you will be able to enhance your productivity. However, if you try to combine the patterns and knowledge of other languages with Rails, then you may reduce the chances of increased productivity.
The working of Rails is based on three main guiding principles, which are explained below.
- DRY (Don’t Repeat Yourself): This principle suggests that using the same codes over and over again is not a good thing.
- Convention Over Configuration: Rails make certain assumptions regarding what you wish to do and how you will do, rather than specifying you to enter a wide gamut of information through endless number of files.
- REST: It is one of the best patterns used for web applications. Organizing the applications around various resources and customary HTTP verbs is the best way to carry out things.
PHP (Hypertext Preprocessor)
PHP is a general use server side scripting language, which is mainly designed for the web development and make highly active and unique web pages. It is one of the very first server side scripting language, developed for being embedded into the HTML source documents rather than using the external files to the process the data. Finally, the code is construed by the Web server with the help of PHP processor module. This generates the web page produced by using PHP server side scripting language. PHP can be combined with a large number of web servers and can also be used as a standalone application on any platform.
MySQL is an open source relational system for database management, which is based on SQL (Structured Query Language). It is a highly reliable and completely flexible database management system. MySQL is presently available in two licensing agreement including free of charge and the subscription to MySQL networks for various business applications.
