課程概述

Database Management Essentials provides the foundation you need for a career in database development, data warehousing, or business intelligence, as well as for the entire Data Warehousing for Business Intelligence specialization. In this course, you will create relational databases, write SQL statements to extract information to satisfy business reporting requests, create entity relationship diagrams (ERDs) to design databases, and analyze table designs for excessive redundancy. As you develop these skills, you will use either Oracle, MySQL, or PostgreSQL to execute SQL statements and a database diagramming tool such as the ER Assistant or Visual Paradigm to create ERDs. We’ve designed this course to ensure a common foundation for specialization learners. Everyone taking the course can jump right in with writing SQL statements in Oracle, MySQL, or PostgreSQL....

This course is having very knowledgeable content. It was having various factors which developed my thinking ability and how to execute the queries. This was absolutely beneficial for me.

Start of this course was very good. But after week 5, assignments became very repetitive and most of the assignments were based on developing an ERD in a tool called ER Assistant. I feel like this part could be covered in 2 weeks time and more stress could have been given to the SQL part of the course.

Though content is good slides and delivery style could be better. More comparison with latest technologies can be provided. Need for more interactive quizzes so as to make it more relevant to fast-changing database world.

Good course with a lot of hands-on assignments. Sometimes the lectures could be brought in a more intuitive way and were a bit 'over-theorized', which made relatively simple concepts seem more complex than they were.

Great content, horrible technical support from Coursera and the team that runs this program (since it is clearly obvious that Michael Mannino just recorded the videos and is not part of the class anymore).

The course was clear, I had difficulties to find course materials, especially examples were used in the video class, I wish they had been put in more obvious places.

The instructors were really helpful throughout the course. Although this was a basic course, but it was informative and very much helpful.

Interesting, I would have liked to deepen SQL knowledge and practice. The conceptual parti seems a little bit too important.

I could not finish because videos were stuttered - even with bigger bandwidth - and as a consequence I could not finish the course and the exercises in my limited free time (therefore, only 2 stars). Is the problem solved now - cause I d like to resume the course again. If that's more successful now I would start the next parts of the specialization.

Thank you for an answer!

can't wait to rate this course! I hope I could give 1 start but to show respect I rated it 2. It's just because I personally don't like the instructor and the way he talks, which could ruin the course! I truly hope we could have another instructor in the following courses or the whole specialization would be ruined and so would my interest in database.

The course and concept were good but the way it was taught in the videos and Lecture slides was absolute garbage. The course was built in utter disdain by the lecturers, it seems. Full picture was always absent in lectures.

Poor english, hard to follow assignments (instructions spread out over 3-4 microsoft word documents with no links between them). Teaches SQL with MixedCase namings, all-named constraints and other non-standard syntax.

No help to upload Oracle Application for use with lesson - not good. Also have to buy the text book which is fine. Should provide option to buy thru Amazon Kindle - easy to use.

Expected a lot more from the course. Also, the teaching style isn't very engaging either.
