# online analytical processing — Database Administrator

As a Database Administrator, understanding Online Analytical Processing (OLAP) isn't about *doing* the analysis yourself – it’s about enabling others to do so efficiently. You're responsible for the database infrastructure that supports OLAP cubes or dimensional models. This means designing and maintaining star/snowflake schemas optimized for fast aggregation, partitioning tables strategically, and ensuring sufficient indexing on dimension & fact tables. Daily tasks include monitoring query performance against these structures, troubleshooting slow-running analytical queries (often involving complex joins), and capacity planning to handle growing data volumes and user concurrency.
