# data models — Database Administrator

As a Database Administrator (DBA), 'data models' isn’t about *creating* them from scratch – that’s usually the data architect’s job. It’s about deeply *understanding* existing ones and how they impact everything you do. Daily, this means interpreting Entity-Relationship Diagrams (ERDs) or logical/physical data models to troubleshoot performance issues ('why is this query slow?'), plan schema changes ('how will adding this column affect our reporting?'), and ensure data integrity. You'll be using tools like database documentation platforms (e.g., Dataedo, erwin), SQL Developer/Management Studio’s object explorers, or even just digging through the system catalog to visualize relationships.
