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.

lessons are not well structured, it would be so much more easy to explain sql
interactively by explainging a concept of sql, then creating a query highlighting what is particularly important of that query and then seeing the result of that querry. Instead it is done in old fashioned power point. First a set of concepts, then some additional information and then application,
E-learning allows for a much more interwoven structure, that might be more initial work for the creator of the course but it clearly would add a lot of value to the students.
Sometimes the course misses to explaing relevant detail.
For example in the last weeks lecture about Date, we learned that we could do operations like
Date('now') - DateColum, and this would return the time difference but only in years, not days, not hours. It would be intersting to know why that is.
