SQL Database Training: Mastering Data Professionally

Kevin KrögerTraining & Workshops

Data is the new oil — but only if you can extract it. SQL is the language that makes it possible. Whether analysts, developers, or project managers: SQL skills are indispensable. Our training teaches SQL from scratch or takes existing knowledge to the next level. Always practical, always with real data.

From SELECT to complex queries

Day 1: SELECT, WHERE, ORDER BY, GROUP BY, JOINs — the building blocks. Day 2: Subqueries, window functions, CTEs, temporary tables. Day 3: Performance optimization, indexing, execution plans. Every concept immediately applied with real data sets. Participants have their own database instance for exercises.

SQL for different roles

Analyst: Focus on selection queries, aggregations, reporting queries. Developer: Schema design, transactions, stored procedures, ORM comparison. DBA: Performance tuning, backup strategies, monitoring. We adapt the content to the roles of participants. Mixed groups also work — the basics are universal.

Which database system? PostgreSQL, MySQL, SQL Server

We primarily teach standard SQL, which works on all systems. For in-house trainings, we focus on your specific database system. Our recommendation for new projects: PostgreSQL. Open source, powerful, with excellent JSON support for modern applications.

Conclusion

SQL is the most important data language — and surprisingly quick to learn. After 3 days, participants independently write complex queries and understand database principles.
