SQL & Relational Databases

Chapter 1: Introduction to relational databases

The first chapter introduces you to the topic of databases. You will learn what databases are and where they are used and why. You will understand how relational databases are structured and know their advantages and disadvantages.

You will learn how to independently write SQL queries to read relational databases and extract company-relevant information. In the first practical project, you will apply what you have learned so far and filter the data using Boolean logic.

Chapter 2: In-depth SQL

In the second chapter, you will refine both your theoretical and practical knowledge. You will learn how to group and sort data with your queries and connect it with different joins. You will also learn about subqueries, which open up new filter options. You can consolidate everything again in the second practical project.

Chapter 3: In-depth database design

In the third chapter, you will focus on the structure of relational databases. To better understand their structure, you will dive into database design yourself and learn about the normalization rules.

In order to put your knowledge into practice, you will learn how to create or modify tables and data. In the third intermediate project, you will design a database yourself and put your design into practice.

Chapter 4: SQL in practice

You will work with a completely new database and apply all the content you have learned independently. The chapter also shows you where SQL appears in your everyday work: You will learn how databases interact with web applications and what role SQL plays in web development. You will also gain in-depth knowledge about optimizing the performance of SQL queries. In addition, you will get an overview of how you can use SQL in practice after the training and which tools are available to you for this purpose.</p
