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....

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.

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).

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

Content wise a very good and useful course. But the technical support on the installation and use of the software needed to complete the course is very limited, and the manuals are not up to date, as they refer to older versions of the proposed software.

The course is well structured with clear objective for each lecture. It starts by asking the main question about the course then summarize the answer and the key messages.

Practice and assignment are valuable to apply and test courses knowledge.

Thank you

Although not have any business intelligence content, I recommend it to people who need to strengthen their knowledge in databases. On the other hand, it should be an optional course for those who were interested in obtaining certification.

if you dont have knowledge of database at all, then its little hard to understand concepts.

but the videos are insightful and helpful..we need to work more and more.

Normalisation is little difficult to understand here...my personal comment

Excellent course, with good video lectures. However, the written course materials, especially in terms of slides and assignment instructions, suffer from poor grammar and an occasional lack of clarity.

Course Is Good One must take this course in order to get background knowledge of DBMS essentials basic query formation and ER Diagrams ER Diagrams is one that must be carefully study.

the data modelling part did not cover advanced topics on super type and sub type concepts. also not a single class on design patterns. wish they had a practical case study assignment.

par Luis D

Fair enough. Good material and content for someone new or that needs to remember basic concepts about databases. Not needed if the main focus is DWH and experience with DB exists

par KrishnaKanth

The DBMS concepts explained in this course, such as ERD design, schema conversion and normalization are very good and has given a good foundational understanding to me.

Good Course with good learning, but at some places it becomes extremely boring which drifts away the excitement and commitment towards the course.

Long but rewarding course, grading it 4-5 because sometimes its boring but thats mostly the SQL, the professor is great and explains really well!

par Ying Y

The teacher's lecture is not very clear and all the assignments are graded by peer classmates which may occur several controversial issues.

par Foad M

Thanks overall is a good course.
