Slowly Changing Dimensions

Slowly Changing Dimensions (SCD) refer to a method in data management that handles changes in descriptive data over time, such as customer information or product details. When this information changes gradually, SCD techniques ensure that historical data is preserved while also reflecting the most current details. This helps organizations track how data attributes evolve without losing past context, supporting accurate reporting and analysis. Essentially, SCD manages the balance between keeping historical records intact and updating current information in a systematic way.
