About the Course

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.

Content: The course content provided sufficient technical database management information, practice and exposure for novice database managers and/or for those learning the introductory aspect of database management.

Approach: The course systematically and effectively employed in-video quizzes and peer-graded submissions and reviews to enhance and further retain the impact of each lesson provided in their modules.

Overall impact: The course fundamentally jumpstarts basic database management principles. To solidly and essentially grasp and enhance one's knowledge of this technical occupation, further continuation of this specialization would be beneficial.

This was a solid course overall and I learned a ton, but there were some things that can be improved, which I have listed below.

1) Videos with more explanations on how to use some of the software would've been helpful. I had to find external videos in order to learn how to use Visual Paradigm and Oracle SQL Server more effectively. This took additional time when trying to solve the practice problems.

2) Grading each other was helpful, but I think an additional grade from the instructor would be helpful in order to get more feedback on errors and things done well.

Great course, learned a fair deal in regards to DB from a beginners POV. The only thing that left a sour taste in my mouth is the poor attitude of some students towards each other. The course uses peer-reviews and sadly some students take joy in poorly grading others whilst providing feedback along the lines of 'Great work!'.

If there was the possibility to actually report these users instead of having to resubmit your work and pray the next set of peers have some decency, I'd happily change my review to a 5 star.

It is sort of 4.5 - not 4 and not 5. The course is not for beginners, it is advanced at times - you'd better do some other beginner-type courses for SQL and databases.

Assignments themselves are not overly difficult but then the quizzes VERY often require going back to slides/notes and often enough simply throw you off - but this might just be me, being still the beginner after 4 courses in SQL.

Overally, it is a very comprehensive course - but you need a lot of time to finish this (yes, 106h isn't a mistake).

Very helpful and well explained.

Two minor comments:

Sometimes, some of the example problems and assignment material (also solutions) have errors/inconsistencies (leftovers from previous versions throughout the years of the material being taught).

Also, it is not possible to provide feedback on peer review results (in a certain occassion a peer reviewer provided a lower grade asking for extra solution items which were not required by the assignment).

Very informative course with thorough explanations on that goes beyond teaching you the basics of databases and SQL and focuses on Database Design practical issues. It is a great source of learning material for both beginners and experienced students/professionals. I highly recommend it to everyone. My only complaint is that it could be a little more extensive in some matters (such as advanced SQL queries, normaiization, etc.).

A good entry into database thinking. Homework is a tad on the high side for people who just want to learn on the side. Also, not clear why diagrams can't be automated directly from the database programs e.g. Access. Why would I draw an ERD and then design a database separately - better just design the tables and the diagram directly; then you have your ERD from the program e.g. Access or Filemaker.

I enjoyed the course and learnt a lot about the fundamental skills required to function as a Database Developer/Administrator. I would suggest that the optional textbook be made available through a dedicated platform at no cost to the student. I needed more personal studies after the videos and the presentation slides were not as detailed and therefore not sufficient. Thank you.

The lecture videos have a format that is a bit over structured. It feels like the instructor takes as much time asking and answering an often contrived "motivation" question as he does teaching relevant material. The slides are of sufficient quality however to make viewing the lectures optional. .

I would have appreciated having all the courses documents in single zip file.

It is good - generally- and long at a 7 weeks giving a good grounding in the subject matter.I really struggled to understand some of the lectures in the last week as the oral description often seemed not to match the material being displayed on the screen (seemingly what was being described was a more extensive version of the table being discussed I eventually concluded).

The course was very well presented and was easy to follow. my only problem is that I struggled a little and as much as I was trying to follow and read the recommended reading material, I found that there was not enough time due to the volume of assignments per week. Maybe if the assignments were reduced or we have them every 2 weeks?!

This is a very good course that teaches you many important skills in preparation for the next courses. It does start off with the basics of SQL DDL and DML that most professionals may already know, but later modules that cover design concepts and practice are very good. There are a few errors in the videos but these are easy to spot.

Very comprehensive course on introduction to database. This is an advanced course so you should have some experience with DBs before taking it. The lecturer, Mr. Mannino, delivers a dry, straightforward teaching style. There are plenty of materials but unfortunately, there is little interaction in the forums from the teacher himself.

Good course for broad end-to-end discussion of database design and management. Lectures are decent, assignments and practice problems are pretty helpful. Class takes 3-4 hours/week on average, though it varies by week. Would have like to see more advanced discussion for some of the easier topics/shorter weeks.

Some of the assignments are very tricky in how they are worded which leads to simple mistakes. I also wish the examples would go through each of the type of problems. I learn best through reading examples rather than the theory so when I don't get to see a problem broken down I find it very hard to learn.

The course is very informative, practical and applies to real world Data Warehousing and Business Intelligence development and implementation with more practice and studying the recommended book.

There is more room for improvement in terms of marking and scoring.

But it is very useful and relevant overall.

Very well structured course, with very nice contents. Needs revision for a lot of easy spottable errors, better lecture slides and better explanations. The last module also needs a complete revision because it has errors and it is really not well explained (beside the subject is relatively simple).

El contenido está muy bien, explica las bases teóricas de las bases de datos. Lo único que no he entendido ha sido el orden de las lecciones y es que en las primeras lecciones se tratan los temas más avanzados mientras que en las últimas se tratan las bases para entender y construir éstos

Too many cheaters, updates to the program over the time are not consistent between questions/answers or previous assignments due to haste. Typos. Not enough time spent explaining the later weeks.

Much of this seems easily remedied, but has been overlooked since the launch of the program.

Pros:

-High-quality instruction

-The assignments are helpful for learning the course material

Cons:

-Feedback from other students on peer-graded assignments is not very useful

-I witnessed rampant cheating on the peer-graded graded assignments. This weakens the value of the of credential.

Very nice introduction to databases. The lectures are not very engaging, the plus is there are practical assignments for every week, where you learn the most. First you submit your own solution and then you provide feedback to your peers. I like the format of the assignments.

Me pareció un curso muy completo que sienta las bases para entrar en el mundo de las bases de datos. Se aprende de RDBMS, ERD's, Normalización, entre otras cosas. Eso si, hay que poner mucha atención en los videos por que el tema puede ser bastante abstracto.

I really enjoyed this course, the course instructor has a nice tonality and the presentation are most of the time well structured. The database installation should be covered in more detail and i had to buy the book in order to understand everything. Over
