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

The course is well structured and the tools used for building the conceptual model are quite user friendly. The course has given a better understanding of the database management systems.

Pros: The course content covers a lot of relevant topics on Database Management. Things like Basic SQL queries, Database Normalization, Conceptual and Logical databases, and making ER diagrams are covered in the course.

Cons: Prof Mannino is a bit robotic in his reading out of long sentences and the constant pace of talking. There is tons of repetition of sentences and words mere seconds after they were just spoken. The lectures seem to be a collection of bullet points.

The assignments and the peer review structure is really a low point. There's no specific grading rubric - so points allocation is random and based on your peer's assessment. I had many instances where my right answers were marked as wrong. There is nothing you can do to correct it. Moreover, the questions are iterative and thus the same apparent error carries on and you get multiple wrong scores.

Assignments need to be submitted in documents. Separate documents for each question !! At times, even a one-line answer needs to be in a separate document. Pictures of database diagrams need to be pasted in said documents. It was a bit frustrating to take screenshots all the time. Especially when you make a small correction, and have to take screenshots AGAIN, then paste it AGAIN, and upload AGAIN !!

Summary: Take the course for it's content, and use the assignments as good practice. Don't take the grading seriously. Also, focus on the content rather than the delivery by the professor, and you will still be able to get some value out of the course (and the specialization by extension)
