How do I save history of a table? The DB is already used. Now I got this requirement to maintain some kind of history of table with columns like this:
Item | marketType |cost1 |cost2| cost3
I89 | wholesalers |78 |89|55
What best practice you guy did to keep history? How do I keep a history of things here? What are some of your best practices you think? Would you remove it from the current table and place it in another table?
