In today’s data-driven world, developers must accurately utilize SQL and database functionalities to provide effective and cost-efficient solutions. This presentation covers key database skills for developers at all levels, focusing on design, querying, and optimization.

The topics are categorized by developer levels (Jr, Sr, Ld). We will begin with fundamental topics, such as using the correct data types, and progress to advanced topics, including vectors and artificial intelligence.

We will utilize SQL Server, one of the most commonly used databases globally. By knowing how to use this well-known server, you automatically qualify for numerous projects. Though many database engines have similar functionalities, they use different terms, so everything learned in this session will apply to other database systems you encounter.

How many new technologies will remain next year is uncertain, but SQL has been essential for decades. Mastering SQL can give you a significant competitive advantage!
