You already know how to build a basic web application with the Ruby on Rails framework. Perhaps, you have even taken Course 1, "Ruby on Rails: An Introduction" (we highly recommend it) where you relied on external web services to be your “data layer”. But in the back of your mind, you always knew that there would come a time when you would need to roll up your sleeves and learn SQL to be able to interact with your own relational database (RDBMS). But there is an easier way to get started with SQL using the Active Record Object/Relational (ORM) framework. In this course, we will be able to use the Ruby language and the Active Record ORM framework to automate interactions with the database to quickly build the application we want.

A nice continuation to course 1 of this specialization, deeper dive into RoR, among other things you will learn how to manipulate/display database data and how to authenticate/authorize users!
Great explanation of not so easy to understand concepts. Lecturer provides good example that can help material better and see how what you've learned can be applied to real world scenarios.
Great course. It open ed up my eyes to how simple it can be to generate a workable MVC web application without having to dive too deep into the working of the application,
This course continues the Introduction with the same test-driven approach and delicious intensity of the material. Efforts to finish the course will be greatly rewarded.
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
- The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
- The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
