During July 2025, work focused on enhancing the edanalytics/edu_wh repository by expanding student demographic analytics. The main feature delivered was the addition of a birth_country attribute to both the dim_student table and its upstream data model, bld_ef3__immutable_stu_demos. This required updating SQL models to ensure seamless integration of the new field and maintaining downstream compatibility across the data warehouse. YAML configuration files were also revised to document the new attribute, strengthening data lineage and governance. The work leveraged skills in data modeling, ETL, and SQL development, resulting in richer business intelligence insights without introducing any bug fixes.
