In this course, you'll get a big-picture view of using SQL for big data, starting with an overview of data, database systems, and the common querying language (SQL). Then you'll learn the characteristics of big data and SQL tools for working on big data platforms. You'll also install an exercise environment (virtual machine) to be used through the specialization courses, and you'll have an opportunity to do some initial exploration of databases and tables in that environment. By the end of the course, you will be able to • distinguish operational from analytic databases, and understand how these are applied in big data; • understand how database and table design provides structures for working with data; • appreciate how differences in volume and variety of data affects your choice of an appropriate database system; • recognize the features and benefits of SQL dialects designed to work with big data systems for storage and analysis; and • explore databases and tables in a big data platform. To use the hands-on environment for this course, you need to download and install a virtual machine and the software on which to run it. Before continuing, be sure that you have access to a computer that meets the following hardware and software requirements: • Windows, macOS, or Linux operating system (iPads and Android tablets will not work) • 64-bit operating system (32-bit operating systems will not work) • 8 GB RAM or more • 25GB free disk space or more • Intel VT-x or AMD-V virtualization support enabled (on Mac computers with Intel processors, this is always enabled; on Windows and Linux computers, you might need to enable it in the BIOS) • For Windows XP computers only: You must have an unzip utility such as 7-Zip or WinZip installed (Windows XP’s built-in unzip utility will not work)...




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.

創建者 Ray K


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.

創建者 Hu Y


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

創建者 Daniel F


Very good course, it helped me better understand many key concept about databases, structuring data for analysis etc.

創建者 Nisar H


Good start of specialization. Great instructor and nicely elaborated difference between RDBMS and Big Data Analytics.

創建者 Jenn M


Good grounding for those who have been away from SQL for awhile and are exploring its use in the world of Big Data.

創建者 Sandalu A


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



Great Introduction to the Big Data world and to the infrastructure offered by Cloudera for big data analysis

Overall it is a good course to understand the basics. The quizzes were apt.

創建者 Tristan S


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