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.

should have provided more explanation and help for exercises and assignment questions. The lecture is also not in depth enough.

More explanation of concepts is required. Also it would have been better if SQL code was explained in depth.

Instructor should have explain each code by performing practically on pc instead of showing only image.

not really relevant to 'data science' its more of a general basic introduction to CRUD and joins

examples for important concepts were lacking like the use of GROUP BY and CASE statements
