Description
SQL is THE most important query language you can learn!
It's used by many popular relational database management systems like MySQL . But it's also used by data analysis and big data frameworks and tools like Apache Spark.
Hence knowing SQL opens up an endless amount of opportunities and jobs - no matter if you're going to work with relational databases or if you're becoming a data scientist, knowing SQL will be key!
SQL is a standardized language and therefore learning SQL will help you apply it in all kinds of contexts. Nonetheless, different database systems also support different aspects of SQL or bring their own variations of the SQL language. Therefore, this course dives into SQL by exploring all key features at the example of the two most popular database systems: MySQL and PostgreSQL. All query and command examples are shown for both database systems, ensuring that you feel comfortable working with SQL in either environment!
This course will enable you to write your own (simple or complex) SQL queries, create basic or advanced databases and table structures and work with data of different shape and complexity!
In detail, you will learn:
What exactly SQL is and how the core syntax looks like
How to write SQL commands
