Particularly, a buyer buys three objects: for $5, $10 and $33 and pays for them. All is effectively. Once I as an proprietor of a store step in and, earlier than I’ve delivered these merchandise to a buyer, resolve to descrease the worth of the product, say, #2. Its new worth will probably be $eight as an alternative of $10. And I am going to additionally rename the product #three a bit bit. A buyer then would go to a standing monitoring web page they usually’ll see up to date knowledge. Sure, they’ve paid and the order is being delivered, however the knowledge has already modified within the database. They will be consufed.
And so will probably be I in a 12 months after I am going to have modified the costs once more, renamed one thing, and many others… and resolve to view historical past of the orders for a 12 months.
Query: is there a practise of constructing a snaphot of the present costs, names, complete order worth and different traits of the merchandise that represent an order, in addition to different particulars (chosen transport price and transport technique, taxes, reductions, and many others) for the time being when it is being positioned? Relatively than calculating these dynamically when an “order web page” is opened?
If sure, does it have a reputation? And are there suggestions of easy methods to do it correctly? For that I would should create a number of tables then:
and many others…
that may have the similar construction as their dynamics corresponding ones.
Laborious. Is there a greater means?
