Avis et commentaires pour d'étudiants pour Big Data Integration and Processing par Université de Californie à San Diego

Curso notable, completo y didáctico. Sin embargo algunas tareas se hacen muy complicadas para aquellos sin experiencia ni conocimiento amplio en materia de programación, ya que las instrucciones no ayudan por completo para aquellos más inexpertos.

Great course, great presentation!

Just a bit of information overkill with the many tools and techniques that are presented. I would have preferred less tool examples in the hands on, therefore deeper introduction to those that are presented.

Contents are good. The structure of the course is amazing. Must do program to have an insight into the BigData Integration as this will open basic processing techniques and about few of the tools used in BigData a overview of the same.

The virtual machine for running the environment is, at start, a good idea. But even with 8 core i7 with 8G of RAM laptop, it was sometime painful to process the exercices. Maybe an ubuntu/virtualbox/laptop compatibility...

As a beginner course it is pretty interesting. The only drawback is that the assignments in the end require prior programming language knowledge and familiarity with the user interface which the following course lacks.

The course did not cover in detail the use of PySpark that was required for final submission. Overall a good course to get basic introduction into different Databases and then you can learn in details on your own!

It was a good overview; however I feel that there are not enough examples of streaming processes. Also an example on how to integrate a relational source with a NoSQL one will be valuable for the learners.

There is little instruction for the final task (either for the other tasks).

And I'm confused by the comments in the jupyter for a long time. You have to google many things to complete the task.

Some of the lectures seemed slightly lesser quality with regards to the materials. For moocs especially, I would like to have the lecture better documented in order to download and review later.

Good contents but mostly outdated making the learning to be a bit difficult as most time needed to troubleshoot the tool. Discussion forum is useful. I hope that this course will get updated

Its a bit tough for students having less knowledge in programming to go through Week 6. Kindly revise the Study material to help learners cope up with tha challenges of Week 6 Quizzes

Assigments would be more complexity but for a beginner they are enough to understand framework.

More code practice should be presented. They need to be repeated to remember of syntax

Interesting course but the requirements to use a VM and virtualbox for handson might make it impossible in companies that are not allowing installation of softwares on their employe

Great Course! Provides a good exposure to the tools and utilities. The database part has been done well. The part with the Spark needs some more info on how to use the data frames.

I was a beginner in the area of Big Data and I selected this course due to my interest and curiosity. But the lectures were very clear and I could successfully complete the course.

The quiz was a bit difficult since there was no much guidance on how to sort in descending order and how to find the total times a country was mentioned in a single tweet.

that course had alot of technical training , i enjoyed every bit of it , specialy the final project , it gave you a little guidance with more space for you to develop more

The week 6 hands on activity was very tough as compared to all other activities in the specialization so far. A gradual increase in difficulty would have been better.

Lot of new information, excellent delivery. Given 4 as I feel real-use case flavor is inadequate -exercises could be more intensive, real case studies can be added.

It would be really helpful if there were full time teaching assistant whom we could directly contact for queries, since questions on forum many times go unanswered.

Good coverage of the issues. Splunk exercise smelled like a promotional thing, not very useful. I think the exercises should be harder and on more complex examples.

Very comprehensive overview and well explained. Only the last hands-on exercise in week 6 was as challenging as I would like to see for all the other exercises.

Some problems occur in VM and the use of virtualbox is not good, I use vmware, because I find some problems to run Virtualbox in my PC.

The course needs update.

The Spark component was especially useful when it went into depth about architecture and implementation. Also appreciated the coverage of MongoDB

PSpeaker who is a man is not very good communicating the lectures it's very difficutl to follow him as his tone is not very good for e-learning.
