Hi there,This is a question about data modelling.
I am no expert, but I understand the idea of foreign and primary keys for relationships.
Question - is it necessary or beneficial to create a column with an integer value in the lookup (dim) table as the key even if another column in text (e.g. country) is available to use as a key?
Thanks in advance.Regards George

Hey @GeorgeFP ,
yes, integer is always the best option for the keys.
Like this the performance and also the amount of space in the data model have the best impact.
