강좌 소개

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....

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

No exercises from PostgreSQL neither from Elasticsearch. So I was expecting more about this course.

el profesor no sabe enseñar y no explica bien que se debe hacer en los examenes de programacion, perdi mi dinero en este curso.

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 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

Instructions are less clear than the 3 previous courses, but the discussion forum helped me very much.

The "python" assessments should be more descriptive. It says "Please enter your Python code in the space below the assignment instructions.", which is simply wrong as I had to figure out hours later after trying pretty much everything. And the downloaded book file has some strange characters which don't seem to work fine when using Windows. Had to work around this.

Good one with lots of knowledge packed in, in term of handson it could have been better.
