Welcome to the first steps into the world of databases!
This course will teach you the essential SQL skills that your employer expects from you. In today's world a lot of professions interact with databases. Wouldn't it be great if you could answer some business questions by exploring the data? Or to solve support issues faster, by understanding what data needs to be corrected after a failed process? Maybe you have just entered into the IT area, either on development, testing, support or business analysis and you want to make yourself comfortable with the idea of interacting with a database.
Being able to write SQL queries will bring considerable value in all of the above scenarios.
This course covers:
How a database is organized;
Searching for specific data;
Querying single and multiple tables;
Using table joins;
Aggregating results;
Putting all together - a collection of real-life business requirements, answered using data.
As accessible as it can get!
There is no need to install any software at all. All of your hands-on activities only need your web browser.
Reinforcement quizzes
Along the way, the course sections have almost 50 quiz questions which will challenge you from two perspectives: questions that you may answer based on your understanding of the presented concepts, and more than 20 hands-on questions that rely on your own queries run in a free, accessible environment from your web browser. The quizzes are separate from one another, so you can choose to answer just to the theoretical challenges, if you cannot run your own queries.
Last, but not least, the entire course has 100% reviewed, edited English captions, so you can enjoy the content in crystal clear verbal understanding.
Looking forward to have you on board!
