I am looking for a way to implement historical data with the following EERD (what I have tried, below the image): Entity Relationship Diagram ## What have I tried? - Temporal tables > Didn't work because I use MySQL and it has no native support. And also isn't the best solution (when doing natively) because then I am fixed to one database provider. - History tables > This is a valid option but some things won't work. >For example, I change the supplier name, a new record will be added to SupplierHistory table, and the data in the Supplier row will get mutated. > >Then lets say for example the next day we change the address that supplier was/is linked to, address gets added into history table, row gets mutated... > >But then the History Row of the updated supplier will still be pointing to the old address in the address table? - isActive strategy >This is also a strategy, in which I set fields that are current and valid, to isActive true, otherwise false. There is also a problem with this one: my supplier and customer tables are used for login. So I cannot just add a new row for changed data, because it is linked to the Primary Key, ID, and all other tables reference to this. So I need to change the original row, but then there is data loss. I don't know what to do/try anymore, doees anybody have suggestions? Thanks in advance, Kind Regards,
