I have a SQL structure that could be illustrated like so (simplified):
Parts, Variants, Machines, Persons. Each have different relations, e.g.;
- 1 Part to many Variants
- Many Parts to Many Machines
- Many Persons to Many Parts
I need to be able to add comments to each entry in either one of these tables. So one Part/Variant/Machine/Person can have many comments. A comment entry always contains user_id, timestamp, comment_text
Should I just do a tables for each, e.g Part_Comments, Variant_Comments etc. Or could/should I make one table for all comments and include the table id somehow. So the columns would be something like: entry_id, table_id, user_id, timestamp, comment_text.
Is there a best practice for this?
Thanks
