# create data models — Database Administrator

As a Database Administrator (DBA), 'creating data models' isn’t about abstract theory; it’s *directly* tied to building and maintaining functional, performant databases. You won't be leading requirements gathering sessions – that's usually a Business Analyst or Data Architect role – but you *will* translate those requirements into concrete database designs. This means taking conceptual models (often ER diagrams) and refining them into logical models detailing entities, attributes, relationships, and data types. Then, crucially, you’ll create the physical model: specifying table structures, indexes, constraints, storage parameters, and partitioning schemes optimized for your specific Database Management System (DBMS). Daily tasks include reviewing proposed schema changes, designing tables for new application features, and optimizing existing schemas to address performance bottlenecks.
