Structured Query Language
SQL (Structured Query Language) lets you query, update, and analyze data in databases. It’s essential in nearly every data-driven field, from marketing to healthcare—and especially in geo-information and GIS.
Geospatial data—like map layers, GPS points, or satellite images—often comes in large, complex datasets. Most of it lives in relational databases like PostgreSQL, often with PostGIS to support spatial queries. SQL helps you access and analyze this data quickly. You can, for instance, count features in a boundary or find points within 500 meters.
If you work in geo-information, IT, analytics, or GIS, SQL gives you the tools to explore patterns, manage data, and uncover insights—fast.
What will you learn in this blended learning course?
The SQL Basics course gives you a practical, beginner-friendly introduction to using SQL in real-world, data-driven environments. You don’t need any technical background to get started.
First, you’ll learn how relational databases are structured—how tables, columns, and rows work together, and how data is logically organized. Then, you’ll begin writing your first SQL queries using essential commands like SELECT, INSERT, UPDATE, and DELETE. You’ll also learn how to filter, sort, and group data using clauses like WHERE, ORDER BY, and GROUP BY to get exactly the results you need.
Next, you’ll connect data across multiple tables using JOIN statements. This helps you discover relationships between datasets and create more complete analyses. You’ll also learn how to manage and improve database structure—creating new tables, modifying fields, and optimizing layouts for better performance.
Finally, you’ll apply your SQL skills in geospatial systems like PostgreSQL and PostGIS. Thanks to the blended learning setup—alternating online modules with interactive live sessions—you’ll work on assignments that closely match your professional context and goals.
Why choose this course on SQL basics?
Blended learning gives you the best of both worlds—live interaction and flexible, self-paced study—so you can build practical, job-ready SQL skills. In this course, you’ll learn how to write, manage, and apply SQL queries, including within systems that work with geospatial data.
We begin with a live session where you’ll dive right into working with real datasets. With expert support, you’ll learn how relational databases work and start writing your first SQL queries using SELECT, WHERE, and GROUP BY.
Then, our self-paced modules let you go deeper into key concepts at your own speed. You’ll explore table relationships, multi-table joins, and how to query and filter data across large datasets. You’ll also learn how to apply SQL in spatial systems using PostgreSQL and PostGIS.
Later in the course, a second live session gives you the chance to apply what you’ve learned. You’ll work through practical, real-world scenarios—troubleshoot queries, refine your results, and receive personalized feedback to improve your workflow.
One of the standout features of this course is its case-based approach. You’ll solve tasks that reflect how SQL is used in professional environments—whether you work in IT, analytics, or geo-information—giving you results that translate directly into your job.
By combining expert instruction with hands-on practice, this course helps you move beyond theory. By the end, you’ll be able to confidently query, manage, and analyze data—and use SQL to make smarter, faster decisions in your work.
