Über den Kurs

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 $39 USD per month for access to graded materials and a certificate....

Practice lab assignments were excellent in reinforcing my learning, they were just the right kind of challenging. This course has been the best one in the Data Science Professional series by far.

Clear, thorough, well-designed. Labs give useful practice, assignments and quizzes test the actual instructional content. This course is by far the best in the IBM Data Science specialization.

Great course for learning how to access Cloud Databases using SQL commands with Python! not so great if you are new to SQL

Lecture slides are required. Please note that so much being taught in a small video may slip out of mind and to quickly go through so many syntax would have been possible only if lecture slides would have been provided.

It is not possible to look back into videos again if i want to confirm some syntax.

This course is really only useful if you have zero backgrounds or experience with SQL.

There are not enough exercises and videos are almost usefull

The information in the class is outstanding, the problem is IBM Jupyter Notebooks' kernels fail within 10 minutes, and must be reloaded constantly. The final exam requires 10 answers via Jupyter notebook trial and error, and it took me nearly 3 days of constant refreshing to get this done.

I have many problems when I do my assignment, I think the class don't teach very well

Some of the documents which are referring to IBM cloud are outdated. Otherwise this course is really good some one like who is beginner in SQL.

It's nice and it teaches you about SQL, but it lacks practice exercises and sometimes is oversimplified and can be too easy.

Decent course. The SQL code is somewhat different and you need to practice it a lot. I do not think you get enough practice to really know SQL just from this course. There is only a few labs and even in there you only actually type a little bit of SQL

Overall the course provides the concept of SQL and a great picture. Just with technical issue in the Peer-Graded Assignment, causing spending loads of time to find out the solution, which those time could have been saved.

In the intro to data science specialization, this course is a relatively steep step up from the previous one 'Data science methodology.' Perhaps obtaining some basic understanding of Python prior to taking this course would help

a few issues on the assignment which lead to a couple of extensions in the deadline, adding a month extra to pay for, Not all the screen shots were the same in the demos as the interfaces have changed slightly. apart from that a good course

Not super clear and struggles a bit with accessing and connecting to the DB2 I think the examples should match what is on the assignment and really break down the query language.

Once on cuts through all the challenges using IBM cloud, the learning was great. Glad I know so much more about SQL now.

A little to none explanations, very easy quizzes. Low quality slides. Good if you want to remember lines without understanding what they are doing.

an unnecessary emphasis on using ibm tools which many times don't get interconnected is a big turn-down.

The content is adequate but I found it a bit boring. The classes did not keep my interest.

This course is a "Big MESS" to me. SQL they used is completely different. It doesn't accept the normal SQL statements. Column names are case sensitive and Writing the where clause gave me head-ace. It wouldn't accept the straight comparisons. Columns names should be expressed in quotes.I hate this course

Not great -- mix of SQL and Python that doesn't do enough SQL. I learned a lot of Python just to make simple database connections and run SQL queries -- it doesn't do justice to Python and isn't very helpful to learn SQL that way. The course would be better with just more SQL, and probably not in IBM cloud services.

There were a lot of problems with the online tools needed for this curse. Staff members eventually responded and solved them, but because of it, I went over my time limit and had to pay another month's coursera fees. Seeing as this is an IBM course and the tools were from IBM, I was expecting a smoother experience
