About the Course

Interested in increasing your knowledge of the Big Data landscape? This course is for those new to data science and interested in understanding why the Big Data Era has come to be. It is for those who want to become conversant with the terminology and the core concepts behind big data problems, applications, and systems. It is for those who want to start thinking about how Big Data might be useful in their business or career. It provides an introduction to one of the most common frameworks, Hadoop, that has made big data analysis easier and more accessible -- increasing the potential for data to transform our world! At the end of this course, you will be able to: * Describe the Big Data landscape including examples of real world big data problems including the three key sources of Big Data: people, organizations, and sensors. * Explain the V’s of Big Data (volume, velocity, variety, veracity, valence, and value) and why each impacts data collection, monitoring, storage, analysis and reporting. * Get value out of Big Data by using a 5-step process to structure your analysis. * Identify what are and what are not big data problems and be able to recast big data problems as data science questions. * Provide an explanation of the architectural components and programming models used for scalable big data analysis. * Summarize the features and value of core Hadoop stack components including the YARN resource and job management system, the HDFS file system and the MapReduce programming model. * Install and run a program using Hadoop! This course is for those new to data science. No prior programming experience is needed, although the ability to install applications and utilize a virtual machine is necessary to complete the hands-on assignments. Hardware Requirements: (A) Quad Core Processor (VT-x or AMD-V support recommended), 64-bit; (B) 8 GB RAM; (C) 20 GB disk free. How to find your hardware information: (Windows): Open System by clicking the Start button, right-clicking Computer, and then clicking Properties; (Mac): Open Overview by clicking on the Apple menu and clicking “About This Mac.” Most computers with 8 GB RAM purchased in the last 3 years will meet the minimum requirements.You will need a high speed internet connection because you will be downloading files up to 4 Gb in size. Software Requirements: This course relies on several open-source software tools, including Apache Hadoop. All required software can be downloaded and installed free of charge. Software requirements include: Windows 7+, Mac OS X 10.10+, Ubuntu 14.04+ or CentOS 6+ VirtualBox 5+....

It is a fantastic course for beginners. The modules and the teachers are very clear, and the content is so good.

After this course, I can say I know something about Big Data, no idea before do this course. The examples and the Virtual Machine was so helpful to understand how hadoop works.

Thanks a lot... a fantastic course... thanks true.

I have got very useful information about Big Data and the need for mapreduce programming model and Hadoop Distribution Framework. I had also got very clear understanding of how to run a mapreduce framework using open source cloudera virtual machine. The entire course is easy to read and understand and fun. Thanks for the instructors.

I have appreciated the course as it explains the main concepts of Big Data drilling through until several tools which can be used to implement important operations for Big Data analytics, for example, how does a search engine basically works. It has very interersting topics and will help me up in my daily job routines.

The course was in he sense truly introduction to Big data Domain and discusses the origin and reason Big Data technologies are required.

The only improvement, I would like to suggest is raise the difficulty level of quiz,so that they motivate student to review and understand the key points discussed during tutorial.

Much better than the previous version (2015) with all concepts very well explained, using examples to clarify them when necessary.

I would have liked to go deeper with Hadoop (in last version of the specialization, Hadoop was a separate course), but anyway, as an Introduction to Big Data, this is an excellent course.

I really liked this course! It take you from the ground up and smoothly ramps up little bit into more detail. Big Data is a vast area and I am aware that there's lots to learn, but now I have a better understanding of what Big Data is. Definitely I am taking the other 5 courses in the "Big Data Specialization".

It was a great introduction. The slides are packed with a lot of information, so do take copious notes if you are like me :). This does not delve too much into programming, but do remember you need a computer with 8 GB RAM, quad core processor, etc for the introductions to Hadoop implementation in Cloudera.

Very detailed explanation of concepts, which though might be common but in the context of Big Data is good to go over. The course naturally transits over tops and finally leads you into the main Hadoop , MadReduce concepts which becomes very easy to understand thanks to all the explanation provided earlier

Great introduction to Big Data concept - just right pace, course design, and most importantly, very clear explanation of the ideas, with relevant examples. It appears that both instructors really love this field and doing their best to induce an interest in learners (they succeeded in my case, for sure:)

It was an amazing experience. I got to learn a lot of new things including big data concepts like where it is used, who uses it, why is it important. Along with this also got to learn about data science concepts. Thank you, sir and ma'am, for sharing your practical experience. It was of a lot of help.

As an introduction course is sufficient to learn the basic concepts. I have hands on Big Data for several years and liked to get certified. This course professionally provides concepts. A Data Scientist and Big Data Engineer, I believe that we have a long journey to go and this journey will never end.

I was looking for this type of course of BigData. I have spent hours to read through different blogs and articles. But couldn't get better idea/direction how to start or where to start. This is ideal course for getting started on Big Data. I enjoyed all the slides and hands on very much. Thank you.

Based on a previous course I took, I didn't think that this course would be as informative and practical. As it turned out, this was a great introduction to big data along with a practical exercise using hadoop. Very well organized and professionally done. I will take other courses from UC San

Good,, simple and enough to have an idea of what hadoop is.

Only a few recommendations.

As the course needs a computer with more than 8GB... it would be better to install the software the first day. Just to see if the requirements of the hardware and software are ok.

This is a terrific intro into what Big Data is for those who are interested but aren't sure if they want to dive into the technology behind how Google, Amazon or internet search engines market what you might be interested in. This course will definitely wet you appetite.

Muy bien realizado el curso aborda todos los temas importantes , las presentaciones en video son realmente buenos, las diapositivas interesantes y a la vez llaman la atención. La voz de la presentadora a veces se hacia aburrida pero la información que daba muy relevante.
