对MYSQL数据库实施版本控制的最佳方法是什么？

I have to produce a versioning system to store multiple versions of my articles in a database to allow the user to roll-back if required. My first thoughts are when the user wants to edit an article really I get the sql to no longer update but you insert their information back into the database. Currently the problem is i have an articles table and I am using the ID as my primary key to identify my article (so read more links and so on). If i insert into that table I will have basicly new articles, so I am thinking I need a new table for the older articles but then I have problem of the originals in that first table dbArticles, I also need so why of telling which article they have choosen, for example if they have 3 edits so 3 articles lets all made on seperate days may 1st,2nd and 3rd how I need to show they have choosen the 2nd of May version rather than the latest on the 3rd of May. Any help would be greatly receive thanks, I have to produce a versioning system to store
