 SQL Database Management and Design equips practitioners with advanced techniques for building relational databases from foundational queries to schema design. Covers core principles of SQL query commands, union operations, aggregation functions, and entity relationship modeling. Examines proven methods for multi-table joins, transaction management, and ACID properties. Helps professionals normalize tables, optimize data selection, and design robust database architectures for reliable information systems.

This course aims to provide a comprehensive understanding of SQL usage across various databases (such as Oracle, SQL Server, and MS Access). Gaining insight into analytic functions and techniques for joining different tables within a database will enable participants to shift data analysis operations to the database layer, rather than relying on MS Excel. This knowledge is also valuable for developing any IT system that utilizes relational databases.

SQL serves as the standard language for accessing and manipulating databases.

This instructor-led live training, available online or on-site, is designed for beginners who want to grasp the fundamentals of SQL for data querying and reporting.

Upon completing this training, participants will be able to:

• Comprehend the structure of relational databases.
• Compose basic SQL statements to retrieve, filter, and sort data.
• Utilize aggregate functions to summarize data.
• Execute basic joins between multiple tables.

Course Format

• Interactive lectures and discussions.
• Extensive exercises and practice opportunities.
• Hands-on implementation within a live laboratory environment.
