Лучшие отзывы о курсе DATABASES AND SQL FOR DATA SCIENCE
Course is god enough. However the last assessment is not. Misprints and not clear questions lead to disappointing marks in the end. Also other students marked assessments based on their understanding.
A very useful course with some very interesting datasets/Jupyter notebooks to work through/practice your skills. Offers a good balanced blend between theory and practical/practice. Very good course!
Practice lab assignments were excellent in reinforcing my learning, they were just the right kind of challenging. This course has been the best one in the Data Science Professional series by far.
Clear, thorough, well-designed. Labs give useful practice, assignments and quizzes test the actual instructional content. This course is by far the best in the IBM Data Science specialization.
One of the best course I completed on Coursera. All the learning material is well organised and easy to understand. Also the non-graded sections regarding relational databases are interesting.
Covers the basics, but might be a little difficult for a complete beginner. Manageable, but difficult. Needs more help using SQL within a Jupyter Notebook which should be in the earlier labs.
Great introduction to basic manipulation of SQL tables and working with the IBM DB2 databases by connecting to them with iPython. Very straightforward explanations and very enjoyable tasks.
This is a great review of an important topic. If I knew how much this mattered for the advanced capstone course I would have paid more attention. As it was, I came back here frequently.
Course was well organized, I found the lab exercise to be useful in learning the material. The quizzes and final project were fair and tested my knowledge of the concepts. Great course!
I liked the way this course is structured and I am really happy with the kind of exercise it contains. It would be really great if more details regarding the python script was provided
Really right to the point and efficient. Good examples and short direct videos. I had no idea about SQL before and now I can run good queries and have enough tools to learn even more.
Excellent class. The quizzes are easy, but there are plenty of opportunities to explore the tools and material and learn more. Optional sections are excellent and highly recommended.
I really liked this course and it is worth it for learning basic SQL queries with Python. I wish we could have more practical exercises but on the whole this was an excellent course.
This course is designed very well to get hands on experience with SQL queries for beginners. The exercises were very helpful in applying what I learned. Definitely recommend this.
The course starts from the basics but progresses to intermediate level concepts in SQL, like joins and subqueries, which are required for day to day work in the Software industry.
A rewarding experience because I have been able to learn very valuable information. It is an excellent course. It has helped me in the personal and professional field. Thank you.
It was a very useful immersion to Databases and SQL. The IBM Cloud platform is amazing and a very easy to use environment which fully supported the objectives of this course.
A good start for beginners . it has various labs which will push you practice a lot and eventually you will develop a better understanding of different query types in sql
need to to updated. details regarding IBM cloud is messy and outdated. take to long to connect the cloud. videos slides are of bad resolution. instructor voice not clear
Awesome course! I learned all necessities to apply SQL queries in my daily job, as well as on how to use these in Python when needed. Very practical for a solid start.
