Eka Ponkratova is a data engineer and educator focused on the modeling side of data warehouse construction — the dimensional and relational schema-design decisions that lock in early in a data warehouse's life and become expensive to change later.
Her CourseFlix listing carries two Eka Ponkratova courses: Dimensional Data Modeling (the Kimball-style star and snowflake schema patterns underneath analytical data warehouses) and Relational Data Modeling (the OLTP-side normalisation and integrity patterns). Together the courses cover both halves of a data engineer's modeling craft.
Material is paid and aimed at data engineers and analytics engineers responsible for the schema decisions in their organisation's data stack. For broader content, see CourseFlix's Data processing and analysis category page.
