This course has really helped with optimizing queries that I work with everyday, enhancing my understanding of RDBMS, joins, analyzing and structuring exactly what you need and yielding those results.
A comprehensive course that covers major aspects of query building and retrieval in a management system. The topics were delivered well and the materials/assignments were relevant for skill-building.

Great Course to start with.
Gives a good understanding of SQL on one side en working with databases on the other.
A syllabus of al the code examples in the video's should behelpfull

Overall good course. The lectures could be made a bit interesting and engaging with exercises broken up. Found the lectures monotonous however course material is good.

I think there are not enough examples to help students learn the syntaxes deeply. It seems that some examples that students can code simultaneously can help more.

Videos were lame and didn't bother withe examples much but exercises were good to learn basic SQL (although u can learn same thing from google if not better)

The course starts easy and okay but the last assignment was so difficult. Quiz on what you teach and teach what we failed to understand (Assignment 4) part 3

This is a good intro course. Sometimes some of the content is covered too rapidly and needs additional supportive exercises to truly master the content.
創建者 George A L J•
Course instructor needed some improvement. It felt as though she was reading from cards the whole time and not really adding much value to the course.
Week 3 was a bit difficult. The questions asked in the quiz were little different than that which were in the lecture video. Rest everything was fine

The quiz questions does not match the material provided in the course. There are more easier ways to coding rather explained throughout the course!

The topics are well explained but the videos are monotonus (slides and the teacher talking). I think the course could be more interactive.

Good for learning basics of SQL but not much application and integration of concepts. In general, however, it is good for beginners.

Course would be much better if you can work alongside the instructor. Using presentation slides in a coding class is not ideal imo.

The lecturer maybe is a good data scientist but does not have the skills of presenting or explaining material in an easy manner.
創建者 Chan J J•
should have provided more explanation and help for exercises and assignment questions. The lecture is also not in depth enough.
創建者 Chen K•
Course schedule was good , but content is a little short. To make improvement, should present some example during the video
創建者 Thais S B•
This is a good course for basic knowledge of SQL but the quizzes and assignments are very confusing and badly elaborated.
創建者 Mohsin K•
This is a good course on SQL for Data Science. As you will particularly start from scratch and go uptil tedious methods
創建者 Dhwanil V•
The overall format was quite good but it would be more helpful if more examples are included in the lecture videos.
創建者 TSUBASA T•
This course is helpful for beginners, but I felt that some explanation weren't clear and quizzes were challenging
創建者 Saswata B•
More explanation of concepts is required. Also it would have been better if SQL code was explained in depth.
創建者 Smit P•
Instructor should have explain each code by performing practically on pc instead of showing only image.
創建者 Nick J•
not really relevant to 'data science' its more of a general basic introduction to CRUD and joins
創建者 Ayush K J•
examples for important concepts were lacking like the use of GROUP BY and CASE statements
創建者 Christopher M•
Course teaching was excellent, but the final assignment questions were terrible.

Clear instruction, but quite easy. Would prefer if it was more challenging.
