RAIL Interview Questions
Rail is a web application framework designed to work with the Ruby programming language. Ruby is written by David Heinemeier Hansson. Rail is a framework for building websites. Rail combines the Ruby programming language with HTML, CSS, and JavaScript to create a web application that runs on a web server.
Ruby on Rail is an MVC framework. A Rail is extremely productive web-application framework.

• You could develop a web application at least ten times faster with Rail comparing Java Frameworks
• Configure your code with Database Schema.
• No compilation phase required.
Question: What are advantages of using Ruby on Rail?
Answer:
The advantages of using Ruby on Rail are as follows:
• Programmer Productivity: The Ruby framework is not called Rail for no reason, testimonies abound around the web on how Rail can quickly carry an app from conception, through development, and into production in record speed.
• Open-Source: Rail is open-source and its compatibility with Linux means there are many open-source options available when constructing your solution stack.
• Built-In Testing: Rail enables developers to use supporting code called harnesses and fixtures to quickly draft simple extendable automated tests.
• Metaprogramming: The ability to write code that acts on code rather than data can be a huge advantage, and Rail makes it easy.

By keeping helper classes in a separate subdirectory, the model, view, and controller classes can remain lean and uncluttered.
Question: What are the positive aspects of Rail?
Answer:
Rail provides many features like:
• Meta-programming: Rail uses code generation but for heavy lifting it relies on meta-programming. Ruby is considered as one of the best language for Meta-programming.
• Active Record: It saves object to the database through Active Record Framework. The Rail version of Active Record identifies the column in a schema and automatically binds them to your domain objects using metaprogramming
• Scaffolding: Rail have an ability to create scaffolding or temporary code automatically
• Convention over configuration: Unlike other development framework, Rail does not require much configuration, if you follow the naming convention carefully
• Three environments: Rail comes with three default environment testing, development, and production.
• Built-in-testing: It supports code called harness and fixtures that make test cases to write and

Task 1 - REPORT (P1, M1, D1) Your first task is to investigate web architecture and components involved in website production, and produce a report. In Part 1 of the report you are required to outline the role of the following: ARCHITECTURE: Internet Service Providers (ISP): businesses which provides access to the Internet to their subscribed customers and provide dial-up, cable, fibre optic or other types of Internet access. E.g. Sky, BT, Virgin Media and TalkTalk are examples of Internet Service Providers and broadband providers.

The genre that was created for the final project is the most powerful tool for communication that we have today, the website. Websites can be used for personal, commercial, government, news or educational purposes. One site is usually dedicated to once specific subject or purpose. There are many key elements that can be incorporated into the website like pictures, video, or links to other websites.

Like every other occasion, I had an idea. The lightbulb moment occurred when I started moving my own applications to Heroku, which is a really cool platform that is a service for developers to build apps easier. I had lots of Ruby applications which transferred perfectly, but I ran into a problem when moving my PHP applications because at the time, Heroku didn 't do anything but Ruby. I wanted to move everything and couldn’t because there’s PHP. The
Railroads throughout the later 19th century of history have come to play a major role for the development of small towns we know of today. The railroads played a role into the development of the small town we know as Corinth, MS, which is located in the Alcorn County area.

If America did not undergo these changes we would not be where we are today in society. With such drastic changes in technology and social and political aspects, the United States was completely transformed during the antebellum period.
A therapist ONLY addressing an offender 's mental illness may be problematic because offenders have criminogenic needs that need to be treated in order to reduce criminal behavior. The Risk-Needs-Responsivity (RNR) model of corrections and rehabilitation was designed by Andrews, Honta, and Hoge in 1990. This model has demonstrated the strongest research-support on its ability to explain and treat criminal behavior. Andrews and Bonta have shown that in order to produce a successful rehabilitation program, the program must "respect the individual, have a psychological theory basis, and should work in junction with the enhancement of preventative services". This model reveals the importance of going beyond ONLY addressing an offender 's mental illness and providing treatment relevant to
Selected Articles). His improvements prevented the steam locomotive from sliding from frost, mud, snow, and ice on the rail and wheels. This is because he made the wheels slightly wider, and by giving them multiple traction power (Prologue: Selected
Railroads were so crucial to the second industrial revolution because it created mass transportation across the nation and more commercial trade for goods to be manufactured. This would help make a national market for the United States. America was growing at this time in history more West so with the invention of the railroad this would help create trade opportunities across the nation as well as a railroad system. According to our textbook, by the 1890s, we had about five transcontinental lines that would transport products from the East which were mostly products from farmers and miners were now being sent to the West to be manufactured (Foner). Also, the train would work for four different time zones for the United States.
Even though trains do not have the same speed as Virgin Atlantic which they are two different modes of transport it is still less expensive when compared to Virgin and thus, “the preferred
In a relational database management system the data access is privileged which means that the database administrator has the authority of giving access of data to some particular users which makes the data secure. 3. Easy to use: This type of database uses tables which is better and easy to create and use. Disadvantages of RDBMS: 1. Slow:
