Ben Brumm is an Australian database developer and educator focused on the practical craft of database design — a skill most working developers learn the hard way through years of production data-model mistakes. He runs databasestar.com, a long-running tutorial site on database fundamentals.
His CourseFlix listing carries Effective Database Design — a structured treatment of normalisation, schema design, indexing strategy, and the modeling decisions that lock in early in a project's life and become expensive to change later.
Material is paid and aimed at developers ready to take database design as a deliberate professional skill rather than a side-effect of using whatever ORM ships with their framework. For broader content, see CourseFlix's Databases and SQL category pages.
