Hello Gentlemen,\n\nThis course was very helpful foe me. It enhanced my knowledge about Big Data Integration. Thank you so much for providing me such important knowledge. Thank you once again.
It was a good course, it could have been better if some examples of Spark were also provided in other Languages like Java, people without having background of python may find it difficult.

some of the working files created mischief so it ruined the swing

Last week was a disaster in terms of giving the necessary educational resources. I found it extremely hard to finish the assignment because I couldn't understand the knowledge set required to do it.
I think you must work on making sure students are getting tailored to the functions that you will request them at the end. It was tremendously underwhelming to me to find such interesting tasks and finding myself unable to understand any clear path to perform even the first actions.
I had to research a lot out of the platform and dig up old replies in the forum just to have hints about what I had to do to find the answers you were requesting. If you consider that it's sufficient with what you explained, you're applying an unfair filter to students.
If you didn't mean that, please adjust either this whole module to focus on
* pyspark syntaxis
* clear use cases in Data retrieval and analysis
* evaluating the syntaxis of each function that you will request later
Or just change the last module to make it according to what you've taught. Thanks, even though I found these struggles, I was able to learn.

I am writing a review for not only for this course but for the previous two courses as well.
The points that I want to make:
The first two courses were okay as far as the theory is concerned but I am very much disappoint with this course because of the following reasons:
1.Not enough exercises for MongoDB
2.That means we have to go further to learn more about MongoDB
3. Too many tools outlined in this course but in return, only a few quizzes comprise hardly more than six questions each.
4.The instructors could have opted for more quizzes on Apache Spark, SparkSQL, MongoDB, Spark Streaming.
5.The creator of this specialization should add two more courses down the line namely " Querying Databases using SparkSQL and MongoDB" and another course could be on "Spark streaming and Splunk"
Overall I didn't like this course at all.
I would like to tell the future learners don't register for this course if you want to take lessons on MongoDB, spark SQL, spark streaming, and Splunk. Look for the courses on COURSERA if you want to take lessons on the above frameworks.

The elaborations in video lecture sometimes are too complicated to understand. It should consider all students comes from different industry. For example, the disease/gene relationships, actually it can replaced by GeneA, DiseaseA, etc. Also, the slides are not clear enough for students to capture the outstanding points. It's not good for students to review since it's truly vague of the relationships between the list items. Overall, the lecture is just different to understand, even causing confusion sometimes.
