Learn about databases and how to use SQL to search and manipulate data

On this course from the Raspberry Pi Foundation you’ll learn what databases are and why we use them, exploring how to use SQL to search and manipulate data.

Along the way, you’ll learn about primary keys and table relationships, as well as how to create joins to search multiple tables. In the final week, you’ll finish by grouping and looking at exporting data from the database.

Learning about databases and SQL is a key component of GCSE Computer Science, so it’s important for educators, students, and parents alike to feel confident about the subject.

Skip to 0 minutes and 2 seconds Databases are essential to computing. They underpin everything from search engines to social media, but what is a database? How can you search a database and edit the data inside it? How can you use a programming language to analyse data? This free course will teach you about the differences between spreadsheets and databases. You’ll learn about the importance of primary keys, and you’ll explore the relationships between data across different tables. You’ll take part in practical activities to edit the data within your own computer sales database, and use your new skills to analyse a set of data to search for trends. This three week course also contains peer led discussions, training interaction, and feedback on your knowledge as you progress.

Skip to 0 minutes and 53 seconds You can learn whenever and wherever you want. So whether you’re a teacher with students of your own or simply want to boost your programming skills, this course will help you to take your first steps in using databases and SQL. Sign up now at rpf.io/databases.
