강좌 소개

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

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.

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.

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.
