Much of the world’s data resides in databases. SQL (or Structured Query Language) is a powerful language which is used for communicating with and extracting data from databases. A working knowledge of databases and SQL is a must if you want to become a data scientist. The purpose of this course is to introduce relational database concepts and help you learn and apply foundational knowledge of the SQL language. It is also intended to get you started with performing SQL access in a data science environment. The emphasis in this course is on hands–on and practical learning . As such, you will work with real databases, real data science tools, and real–world datasets. You will create a database instance in the cloud. Through a series of hands–on labs you will practice building and running SQL queries. You will also learn how to access databases from Jupyter notebooks using SQL and Python. No prior knowledge of databases, SQL, Python, or programming is required. Anyone can audit this course at no–charge. If you choose to take this course and earn the Coursera course certificate, you can also earn an IBM digital badge upon successful completion of the course. LIMITED TIME OFFER: Subscription is only …

    There are a large number of practical examples which reinforce the theory thought in the video lectures. Would highly recommened doing the optional parts of this course as well as it will benefit the person taking the course. All in all a great course.

    Basic SQL, course needs to be updated to reflect changes to IBM cloud (or better yet, don’t use IBM cloud). You can find better courses on SQL on Coursera/other MOOC sites.

    The class was very enjoyable and very easy to follow. My only complaint is that if the final assignment is going to be assigned such a high weight, then it should require more than 1 person to review it. My assignment met criteria to receive full points, but the person who graded mine clearly blew through it and assigned me partial credit where I should have received full credit. I still passed and enjoyed the class, but it was frustrating to successfully complete the assignment only to be dinged by some inattentive grader.

    The course is good but sometimes the exercise texts are not very clear and some of the lessons are very straightforward, leaving many doubts. The course should have a larger series of exercises and an automatic correction system that facilitates the review of the exercises. In addition, it would be interesting to have a module on how to use IBMDB2 without the online platform, but through Jupyter on the computer.

    Videos were good length but automated voice over, learned SQL in the context of their proprietary Db2 database. To their credit, the lectures were fairly short but contained enough information to take notes and learn SQL, and I finished the course in a short period of time. They don’t babble which is nice.

    This course offers a good first overview of working with SQL and database systems. It relies a bit too much on external IBM tools while a more general approach, with the open to get introduced to IBM tools, would be more appropriate.

    The only comment is that the usage of DB2 of IBM may not be available all the time. So, suggest if you can mention other tools that can be used locally on PC to help student to follow up and complete the tasks.

    Of the courses in this professional data science certificate I have taken, this is probably the best designed one. The labs force you to think and apply what you learnt in the video and not simply make minor modification to example codes. By the end of the course, I have internalized some of the commands. Overall, the labs were rather effective at drilling the concepts into students. Some of the labs in the second week were rather lazily written. Instead of asking students to practice what they saw in the videos, all labs should contain actual questions that ask students to apply what they have learnt to new examples and problems, forcing them to think about what they have learnt. The grading system is also in need of improvement. Some graders do not seem to know what they are doing. Simply resubmitting the assignment can result in a drastically improved score simply because the first grader was marking down answers that were actually correct. Perhaps there could be multiple graders assigned to any single assignment and the average score taken, or something to that effect.

    The content of courses are great! Went through step by step until a high technical level. Unfortunately, the lab is always out of server, me and others users have been reported the same problems every now and then and nothing changed. I finished the course without practice the labs and I can’t check the exercises to start an own project! Apart from that the whole course is worthwhile.

    For a beginner it is an excellent course. Step by step hands on examples help one to negotiate and learn patiently. Now I have much better understanding of why DBMS is so critical and how one has to use the cloud DBMS remotely. How the tables are created and the significance of Primary and Secondary key. How the queries are run. How to do the joins to handle data from multiple tables.

    It will be better if instructor could provide more tips or attentions or common mistakes on using SQL, for example, when retrieving string results from multiple tables and joining them together, their format should be exactly same, or there will be no value though the syntax is correct. Then we will avoid wasting more time on trail and error.
