Love this course. Helped me understand angular 1 concepts very well and with great explanations and coding examples. Keep it up and keep eating those cookies :)

Overall this is a great course with a lot discussion on MongoDB and using Ruby on Rails to build web services. However, it would be better if the professor can give more explanation on codes and syntaxes rather than just copying and pasting lines of codes to command line and show what the results are - we can do that ourselves, but we want to know why that works. And also, the projects are much harder than what I expected - project 2 would definitely take more than 8 hours and so does project 3. And some of the implementations in the projects are given a great deal of hints but I actually did not find the corresponding materials within the lecture, and I sometimes don't know why I have to do it that way even though I managed to get the codes work. But as a whole this course is great - it offers a different look at database and this is the only course that talks about web services rather than web apps in this specialization. I gave my opinions not because I am complaining, but because I wish I could contribute to its becoming better.

Not up to (my) expectations.
This course is not bad, I've seen much worse on coursera, BUT is it good enough to justify the investment, I'm not sure. Following the video is tedious, and boring. The instructor gives the impression he follows a recipe, and never explains why he's doing what he's doing: he rather describes what we already have on screen. I can read, thank you! I expect much more from an online course, supported by a reputable university. I expect some deeper explanation, I want to be taught why things are the way they are. Why do we choose MongoDB over a conventional RDBMS ? What are the benefits ? the drawbacks ? This should be explained to put things in context. Toward the end of first week, the instructor switches to "MongoLab". He never introduces it or explain what it is! One sentence would be enough to put things in context.
I'm not on coursera to follow a soulless recipe, Technical matters are often dry, repetitive, boring, I need to feel some excitment from the instructor, and I need him to put things in context, to unveil what is not obvious.

I recommend this course to anyone who wants to start learning about document-oriented data model databases. It helped me a lot, since I have mostly worked with relational databases and I got curious about Mongodb.

The layout of this course is extremely well reasoned out. Each module gives important stepping stones for the students both to understand and to get practical skills to use the material after the course. For me it was an extra bonus to learn about teh Rails API in the 4th week of the course. I will surely need that in the future. All assignments include very thorough guidance on how you can check your own work one step at a time all the way through. In fact I have never before attended a course where so much effort had been but into that part by the teachers. Much praise for that. The graded assignments were hard. I had to put in a quite considerable effort in each of them, especially week 3. Much more work than I had anticipated. However I cannot point to any part of the material that could easily have been left out. Everything we learned seemed useful and important. So in spite of the hard work I am happy that I stayed in there to the end.

Saps away a lot of time for beginners, but every hour spent is worth it! Best course so far in the specialization.

Very nice course with good and fast support through the exercises. I am still a newbie for Rails and Mongo, but I think I made a good introduction to the topic. Be aware that the course may get demanding from time to time.

I am a full-stack developer working mainly with Ruby on Rails.
I took this course to learn about MongoDB and how it can be used with Rails, as well as to pick up certain aspects of Rails that I have not been using as much (like JBuilder)
The materials and assignments are very detailed, which shows that a lot of effort has gone into them. Although some of the work turned out to be more time-consuming than expected, I enjoyed going through it and seeing the results.

A most excellent course! I learned a lot more than I thought I would. My only comment is that the time estimates were way off for me -- I ended up spending up to four times as long as the estimate, on each week's assignment. But it was worth it.

Great way to learn about MongoDB and it's integration with Rails framework.

Wow, not easy, time estimates to complete course are not accurate unless you already have a understanding of the concepts, but 100% worth the time. Instructors provide prompt feedback and most questions have already been asked so typically you can find what you need when you get stumped.

I thought this course was really challenging and that made it worth it. I was expecting the course to just be "here's another type of database, and here's how to use it in Rails". But they went into all the features unique to Mongo. They showed things you can't do in ActiveRecord. The last project being an introduction to making APIs was great too. It really got me thinking about all the types of web apps I could make.

This is a great course. It is challenging, but that comes with the territory if you want to write code. I like the fact that the assignments are challenging and long; the only issue I had is that I work full-time and hardly have the 20+ hours a week to spend on the programming assignments. Also, the estimated times listed for each assignments are not realistic for somebody learning the topics in this course for the first time. I would recommend this course to anybody wanting to learn how to develop web apps and api web services using Rails with MongoDB as the backend. Just be prepared to dedicate a lot of time each week. Especially week3's assigment. I ran out of time and had to transfer to a new session to complete the course because of my full-time job. It would be beneficial for students to have a spare week, in between the third and fourth assignment.

This course is a lot of hard work but, take hard work to become proffesional
