Informações sobre o curso: 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 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.
Para quem é direcionado este curso: This course is designed for anyone interested in learning SQL, especially those who want to apply SQL for data science.

Apart from errors in the open source tools for the hands on labs, this course is fantastic and well crafted to introduce Databases and SQL. the optional sections are useful for those without good grasp of knowledge about databases and their types. make sure to take them. The labs are good, but always there is connection problems. If they will fix this, it will be one of the best introduction courses out there.
Perfect course to step into Data Science field!!!!
best course for sql for a begginer to learn from
ng
great course, great tools
