📱 Data Modeling

A video guide on data modeling and its types. By the way, I recently published an article where I tried to describe all modeling methodologies.

The video covers:
😀The levels of modeling: conceptual (when you describe business objects and processes with abstractions), logical (the level where entities and their relationships are defined), and physical (directly tables and their relationships).
😀It analyzes three physical-level modeling methodologies: Dimensional (i.e., Star), DataVault, and OneBigTable.

It's unclear, though, why OBT is included here. Is it commonly used in foreign projects?
