Mickey Stuewe wants to track changed data, but has to use Standard Edition:
I use a pattern that includes four fields on all transactional tables. This (absolutely) includes lookup tables too. The two table types that are an exception to this pattern are audit tables and error tables. I’ll cover why later in this article.
Four fields include CreatedOn, CreatedBy, UpdatedOn, and UpdatedBy. The dates should be DateTime2. CreatedOn is the easiest to populate. You can create a default on the field to be populated with GetDate().
This is a common pattern and works pretty well. The trick is making sure that you keep that metadata up to date.
