# MDX — Database Administrator

As a Database Administrator, MDX isn't about transactional data like SQL; it’s about *analyzing* that data after it's been aggregated into multi-dimensional cubes – typically within Microsoft Analysis Services (SSAS). Think of SQL as building the house, and MDX as inspecting the blueprints to understand how everything fits together. Daily tasks involve writing MDX queries to validate cube design, troubleshoot slow query performance *within* the cube, or create calculated members for KPIs that aren't directly stored in the source data. You’ll be asked things like 'Why is our sales forecast off?' and MDX lets you slice and dice the data to pinpoint the root cause – often revealing issues with aggregation logic or dimension hierarchies.
