# Select Data Structure

PowerKPIs support different data structures. You can create KPI cards from either wide data (your KPIs are stored as measures in columns) or long data structures (your KPIs are stored within dimensions in rows).

Navigate the images and select the data structure type that fits to your data and use case.
