This Specialization teaches the essential skills for working with large-scale data using SQL. Maybe you are new to SQL and you want to learn the basics. Or maybe you already have some experience using SQL to query smaller-scale data with relational databases. Either way, if you are interested in gaining the skills necessary to query big data with modern distributed SQL engines, this Specialization is for you. Most courses that teach SQL focus on traditional relational databases, but today, more and more of the data that’s being generated is too big to be stored there, and it’s growing too quickly to be efficiently stored in commercial data warehouses. Instead, it’s increasingly stored in distributed clusters and cloud storage. These data stores are cost-efficient and infinitely scalable. To query these huge datasets in clusters and cloud storage, you need a newer breed of SQL engine: distributed query engines, like Hive, Impala, Presto, and Drill. These are open source SQL engines capable of querying enormous datasets. This Specialization focuses on Hive and Impala, the most widely deployed of these query engines. This Specialization is designed to provide excellent preparation for the Cloudera Certified Associate (CCA) Data Analyst certification exam. You can earn this certification credential by taking a hands-on practical exam using the same SQL engines that this Specialization teaches—Hive and Impala.

It is no common for me to put 5 star score to courses, but this courser was literally comprehensive.Thanks to all staff and instructor.
SK
This is Very good course for a beginners, it gives you lots of exercises to practice in vm and course material is Really really good but only thing is you have to read a lot ,
MZ
Well structured, nice visuals, good information. Unfortunately it is not good for already experienced people with a bit of background on the subject.
SC
Awesome course. Lots of practical use of analyzing big data with SQL. Thanks Ian for teaching the course. Highly recommend this course if you would like to improve/refresh your SQL skills.
RA
The course spanned across multiple areas. It was great learning.
AM
Precise and engaging content!Takes a definitive and well-explained approach towards teaching Big Data to you :)Satisfied with the what the content had to offer.
AS
Great course!I would just add 1 more full business task for practicing before the final one. Anyway, I find the course very useful with clear and understandable explanation.Thank you!

It would have been nice if videos would have been present instead of reading. Also a more deep diving would have been done in concepts like bucketing and indexing.
SK
Thank you for bringing such a Awesome and High quality course - Cloudera. Course instructors are just exceptional in presenting the course material in a clear, concise manner!
SA
The course is really informative and laconic. It covers everything you need to analyze data using SQL. Would recommend everyone who wants to learn SQL.
GK
Very good material and the labs using the VM are wonderful hands-on experience.

If you are an "absolute" novice with no knowledge about RDBMS and Big Data systems and all help from YouTube videos and other online resources have been of little to no help then you must take this course. It teaches you the very fundamentals of database design and builds your knowledge from ground up. It takes you from "What is DBMS" to a much higher level in a very short span. And Glynn is perhaps the best teacher you've ever met in your life! Give this course a try and you'll be happy and better off for having done so. Good luck and "THANK YOU GLYNN!".
If you don't have any background about SQL and you don't know where to start, I think this is the best course to start. It simplifies the concepts into easy ideas to be understandable.
If you've never had practical working experience with databases, this course gives so much valuable context to anyone pursuing a career working with big data. The material focuses on preparing you with relevant knowledge about database systems (past and present), that supports you in the next courses of the specialization which are more hands-on with coding in SQL-dialects. Initially I did not feel convinced I wanted or needed to understand much database theory covered in this course, and wanted to skip to the hands-on practice. However I've completely changed my mind after completing the course which has drastically improved my understanding of all current big data-base systems, their features, pros/cons, why there are so many variations, and helped me understand which database systems I want to focus learning on next. Unlike googling/studying myself online, I can actually be sure that the information given in this course is relevant and up to date. I highly recommend it, especially to anyone who hasn't had much working experience with databases yet- you'll gain a much better understanding of the current landscape of database technology.
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! :)
informative background info of Big Data that's good to know about. not too simple or too challenging.
Amazing course, full of useful information, the quiz are good way to test your knowledge and the instructor is an expert in this field and has very good presentation skills.
Good course to understand the foundations of big data using good examples and real life problems.
It was a productive experience overall and a good introduction to the world of big data. A good way to understand the difference between some SLQ engines and how to organize huge amount of data. I'm looking forward to begin the second one.
This is an introductory foundational course for SQL. You will not actually use the SQL commands. It gives good, clear, and interesting instructions on the concepts and structures of big data and SQL applications. I like the instructor, course format, and level. It makes sense to continue on to the next course in the series to practice SQL commands and the software applications.
Very good introduction to SQL applied to Big Data. The instruction is very clear and the lectures are very relevant. The quizzes and final assignment were mostly appropriate for checking knowledge against subject matter. The VM was also a very effective training aid.

I Really enjoyed the course and the instructor is perfect
Big data is the one of the most emerging technologies in the world and this cloudera course will definitely help us to understand the hive and impala with practical.
This course was great, I have two years of experience with SQL since I am using SQL in my role of software developer. I've have taken this course in order to initiate myself to big data a field in which I am interested. This course was great experience, it has allowed me to really undestand SQL, RDMBS concepts, learn fundamental concepts of big data and be aware of big data tools used for analyzing huge datasets such Apache HIve and Apache Impala.
Excellent course! This course, together with the second in this series (which I have already completed) is arguably the best course to start with databases and SQL. Everything is explained from scratch and in a well-organised way so that it's effortless to follow and gain knowledge in a short period. The quizzes are well-drafted and logical, and the course does prepare you for that, unlike in many other courses!
I learned so much. I intended to continual review the entire material in this course. Thanks All.
Best course for learning the basic concept about big data and SQL.
Excellent class, earned a lot from the lecturer. Thank you.
Excellent fundamentals for data engineering
Great course, I'm amazed
great course
