About the Course

In this final course, you will explore database architecture, PostgreSQL, and various scalable deployment configurations. You will see how PostgreSQL implements basic CRUD operations and indexes, and review how transactions and the ACID (Atomicity, Consistency, Isolation, Durability) requirements are implemented. You’ll learn to use Elasticsearch NoSQL, which is a common NoSQL database and a supplement to a relational database to high-speed search and indexing. We will examine Elasticsearch as an example of a BASE-style (Basic Availability, Soft State, Eventual Consistency) database approach, as well as compare and contrast the advantages and challenges associated with ACID and BASE databases....

This class is very helpful. Professor not only taught technologies, he also told the scenarios and stories. This make me to understand what and why much easier. Thanks for the excellent class!

Excellent course. I knew a littel SQL before the course but this class has greatly improved my knowledge of not only SQL, but Postgresql knowledge, and overall database systems and design.

The course is called PostgreSQL for Everybody. I don't think that this is accurate. The first 2 courses are an introduction to PostegreSQL but the later 2 are not. Also, calling them courses is a bit much. It is clear that the 4 courses were actually just 1 course and the weeks belonging to the original course were transformed into a full course (even to the point that the last "week" of the las course only has a 2 minute video. Many other "weeks" have similar extensions with maybe 10 to 15 minute videos only).

The assignments are short, not well thought and do not make you learn. In many cases the assignments are only about copying and running provided scripts.

The last 2 "courses" are way off topic for a course called PostegreSQL for everybody.

This class has very little content that actually teaches elastic search. A more appropriate title of this class should be "A short history of SQL vs NOSQL systems". Like another reviewer has said, you can get perfect scores just by cutting an pasting code snippets. I am very surprised that a very highly rated instructor like Dr. Chuck can feel good about calling this an Elasticsearch class. There are only 3 actual programming assignments in the class and in my opinion they teach very little about Elasticsearch.

This course was fairly easy comparing with other courses. But good to know about those practices, which were introduced here.

Thank you Dr. Chuch!

This is ~10th Course from you, which I've completed

I really loved the content of this course and the way Dr. Chuck taught! One thing which I think can be improved, is that in the code walkthroughs, I would prefer if the code is written from scratch, instead of copying and pasting already written code.

The course was excellent, covering as breath a material that I had not expected at the beginning. Professor Severance emphasized the fun of learning something new and the utility of the information provided. I strongly recommend the course.

Thank you for the knowledge in this course. I have learned about Database architecture and Elasticsearch which will help my work in the future. I will enroll the courses by your organization and introduce my friends about it.

The course topics are well-organized in a simple manner. I personally liked these courses. As I learned more information on my own, I repeated it here again. I express my gratitude to the creators of the course.

I love the way Dr. Chuck structure the lectures covering history, technology and application of databases. Understanding all this aspects makes you finally see the big picture on the topic.

The course is interesting and capacious. There were 2 things called dificulties. The first - it was hard for me to understand what the code I have to put in the "answer-field", like should it be really the code or the response from terminal after command' execution (this option). And the second - the assigments are written in Python. I am junior developer and use javaScript. I hav never tried python before, so I spend some time to became familiar with basic things. Everything else was perfect.

This course openned a lot my mind about how ACID and non ACID databases work and I certanly feel more confident to analyse cenarios where one or another architecture are better

I was wondering if it would be possible for the instructor to cover some basic concepts before diving into Elasticsearch, as it would help me better understand the material.
