About us

Tabbulyn was created as a space where SQL knowledge is presented clearly and sequentially. The idea arose from the need for materials that support natural skill development and gradually build an understanding of data logic. We wanted to design an environment in which each section flows into the next, making learning calm and well-organized.

Our journey began with studying how people process information about tables, relationships and queries. We realized that effective learning requires not only facts but also a logical sequence that reveals how elements interact. This led us to create an approach based on examples, written exercises and smooth topic progression, supporting learners at different stages of their SQL exploration.

At Tabbulyn, every topic follows a defined trajectory where new information connects to what came before, creating a clear and predictable path. We view SQL as a language of logical relationships and explain it through structures and real situations. Our materials help learners notice important connections, encourage analytical thinking and build a comprehensive understanding of how data operates.
