Slowly Changing Dimensions Surrogate Key. A using slowly changing dimensions. This article provides details of how to implement different types of slowly. This appendix provides a brief introduction to the different types of slowly changing dimensions. It also goes through a case study. Instead of using natural keys (e.g., customer ids), it is better to use surrogate keys, which can simplify. Slowly changing dimensions in data warehouse are used to perform different analyses. Type 2 dimensions are stored in a way that a new record is added every time there is a change but the history is. This surrogate key gives the dimensional design flexibility to handle changes differently than they are handled in source. It also makes this key immutable and allows the appropriate surrogate key value to be discerned without looking it up in the.
