Microsoft SQL Server (berufsbezogenes Zertifikat)

Build on your foundational SQL knowledge by learning data manipulation techniques in SQL Server. This course focuses on using INSERT, UPDATE, and DELETE statements to modify database contents while maintaining data integrity through proper transaction management. You'll learn to implement transaction control mechanisms, understand isolation levels, and prevent common concurrency issues. Through practical examples, you'll implement error handling strategies and explore the principles of ACID compliance essential for reliable database operations. The course also demonstrates how generative AI can help optimize complex SQL operations and troubleshoot transaction issues. By the end, you'll confidently perform data modifications while ensuring database consistency—crucial skills for any database professional.

Develop expertise in relational database design principles and implementation using SQL Server. This course teaches normalization techniques, entity-relationship modeling, and schema optimization to create efficient database structures. You'll use DDL (Data Definition Language) statements to build and modify database objects while enforcing data integrity through constraints. The advanced querying section covers complex joins, subqueries, CTEs, and aggregate functions that enable sophisticated data analysis. You'll also explore data warehousing concepts and learn to leverage GenAI to assist with complex query development from natural language descriptions. By the end of this course, you'll be able to design normalized databases from scratch and write advanced queries that extract meaningful insights from complex data structures.

Learn the techniques that make SQL Server databases perform at their best. This course focuses on database performance tuning through proper indexing strategies, query optimization techniques, and execution plan analysis. You'll learn to identify bottlenecks using SQL Server's performance tools, implement appropriate index types, and rewrite inefficient queries. The course also covers stored procedures, user-defined functions, and views for encapsulating complex logic and improving maintainability. Through hands-on exercises, you'll analyze real-world performance scenarios and implement solutions that dramatically improve query response times. The integration of AI-assisted optimization techniques shows how modern tools can complement traditional performance tuning methods. By course completion, you'll be able to transform slow-running queries into high-performance database operations.

Develop essential database administration skills focusing on security, maintenance, and business integration. This final course teaches you to implement SQL Server security through authentication, authorization, and data encryption while ensuring data integrity through validation constraints and auditing. You'll learn critical maintenance tasks including backups, recovery, and index maintenance to ensure database reliability and performance. The course also covers integrating SQL Server with Power BI for creating interactive dashboards and reports that transform raw data into actionable insights. Additionally, you'll explore modern application integration patterns and API connectivity. By completing this course, you'll possess the comprehensive skill set needed to securely manage database environments and bridge the gap between data storage and business intelligence.
