Temporal tables and Temporary tables are two very distinct concepts. Your link has absolutely nothing to do with this question.

Type 1 SCD - This concept overwrites the existing value within the dimension table with the new value without retaining the old data. Type 2 SCD - This concept maintains the versioning of the table. It creates and adds a new row with the new value and maintains the existing row containing the old value which usually is required for historic and reporting purposes. Type 3 SCD - This concept creates a new column with the new value in the existing record but also retains the original column containing the old value which usually is required for historic and reporting purposes.
