The course is an excellent overview of database technologies and introduction into big data. Useful also for those who already worked with a few SQL engines. MIllion thanks to the creators! :)
Awesome foundation to build on skills of query and analysis of big data and to use big data technologies like Hive and Impala\n\nI Really enjoyed the course and the instructor is perfect

When it said foundations they weren't kidding. I enrolled thinking I would be learning basic SQL coding skills but none of that is taught in this course. It mainly revolves around the different programs available, which is the most appropriate to use in which situation and knowledge of good practices in designing a database. Only the final week taught something more hands-on/technical. I personally think it would've been better to splice this information with a course that teaches actual SQL programming.

Really great introductory course to the conceptualization of SQL databases and the varying kinds. If you are under the assumption that all relational databases are similar, this course will teach you that they are not. Big data has much different implementation challenges than something of relatively smaller size. Specific software/RDBMS have to be written to deal with the volume of data, particularly due to distribution of storage.

I think this course is great, even for people with SQL experience already. It shows the different ways SQL can be used in a big data context. It was good to get a gentle introductions to Hive and Impala also.
I wish it had more assignments (hands-on), but I hope there will be more in the upcoming courses of this specialization.

One of the best course I have taken in Coursera !! I thoroughly enjoyed the course material and the instructor lesson and way of teaching . I am looking forward to the hands on session in the next course

Very good Introductory course for getting to know about Big Data . The course structure is well made,I really liked how it took basic Database concepts and then relating that to Big Data.

no real hands down, just a bunch of videos, in the end you end up installing a VM with some database samples, but again, no real hands down beyond that, you are on your own to learn...

It tells you about all the DBMS AND RDBMS stuff and why Big Data is needed and how the changes have occurred but this one is really necessary for one to Know.

The first course of this specialization was good and Instructor Sir, Glynn Durham was a good instructor with lot of explanation, examples and acronyms too

Useful concepts for starting to understand and learn how world of big data works. Would have enjoyed to be a bit more practical at last assignment.

Good and clear lecture. Only the content is very basic and there is no hands-on activity. It could be compressed to less weeks.

Very Detail heavy course compare to practical aspects.However in week 5 we are introduced to Hive and Impala.

Useful information but I was hoping for more hands-on experience
