À propos du cours

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....

Very good to every beginner out there trying to get into database management , tasks are really educational , only the normalization section needs more clarification. but as a total it is awesome

Excellent introduction to DB Management, I learned everything that I wanted to learn from it. I highly recommend it and actually I am already enrolled to the next course of the specialization.

Peer Review is sub-optimal

Good Solid

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.

This is the most horrible online course I have ever taken. The topic is super interesting but explained rather poorly and the material is not really good (also perhaps too many topics are included in the course).

One of the most horrible and stupid things are the assignments: these are not graded by the teachers but by other students; this leads to the fact that many students just upload random material because in many cases the peer review is not really performed and the assignment is considered approved anyways.

On the contrary, I have experienced some revenge-behaviour from one of the students that submitted empty assignments: he/she marked my submission as not relevant (because I did so to him/her twice since he/she uploaded only an empty template)!

In the end you do not even have the chance to check if your assignment was actually good or not

There are many other drawbacks to this course but I really do not want to spend not even a second of my time with it so I'll close it here! stay away, it's mostly a waste of time

It's ok to have a peer review assignment. But it's obviously not appropriate to have all the assignments as peer review assignments. It is just taking way too much time to wait for scores. For every problem, you have to upload a single file for it. I cannot understand the point of doing this except for wasting time.

Software requirements are too strict. VM Machine is running slow on my mac so I went MySQL for the first two courses but Oracle database is still required for course 3 and course 5. So how should the students like me do to complete the assignments?

After I completed the course 1-4, I unlocked course 5, but it's informing me that this course content does not start until June. So I have to wait for 2 months and pay another fee to complete the specialization. But I am not going to do that.

I was excited about this data warehouse specialization but now I am just disappointed. I would not recommend this course to others. Maybe try something else.

In wk3 my DB is totally messed up and I do not know where to find the CORRECT create statements to recreate the DB that the assignments expect! It shouldn't be too difficult to provide one page that gives the commands to execute to create the DB that is used in each week (for each week separately). Due to that I'm un-enrolling from this course.

This is the worst course I have ever seen in my life, I'm ain't lying these guys use the terms which they haven't thought and they use it so frequently as if they have thought it, One who were teaching may be industrial experts and have lot's of experience, but one thing to note is:

Teaching is an art...

The course has very poor support to install applications for the course. The teacher is going though the course at a very high level. Not going much in details. I would rather read Definitive Guide to Data Warehousing and it provides more information than this course.
