Working knowledge of SQL (or Structured Query Language) is a must for data professionals like Data Scientists, Data Analysts and Data Engineers. Much of the world's data resides in databases. SQL is a powerful language used for communicating with and extracting data from databases.
In this course you will learn SQL inside out- from the very basics of Select statements to
advanced concepts like JOINs.
You will:
-write foundational SQL statements like: SELECT, INSERT, UPDATE, and DELETE
-filter result sets, use WHERE, COUNT, DISTINCT, and LIMIT clauses

Reviews summary
Databases and sql for data science with python
Learners say "Databases and SQL for Data Science with Python" teaches the basics of SQL and Python database operations clearly. They note the wide range of labs and exercises available to practice these skills, which many describe as helpful. Students also mention the optional "Honors" modules, which provide further learning opportunities.
However, some learners report technical difficulties while using IBM's Cloud platform and database, which they say detracted from their learning experience and caused them to lose time. Others mention frustrations with the final peer-graded assignments and a sense that the course is structured to promote IBM products and services rather than solely focus on teaching data science concepts.
Overall, learners say "Databases and SQL for Data Science with Python" is a good option for beginners who want to learn the fundamentals of databases and SQL. However, they recommend being aware of potential technical challenges and encourage students to supplement their learning with external resources.
