I've got the same issue that you do. Here is my thinking thus far:
Say I have a transaction table:
Record_Key
Service_Date
Item_Code
Item_Quantity
I'm considering this structure for the rate table:
Item_Code
Effective_Date
Rate
It's practical from a data entry perspective, but I can't seem to
SELECT price FROM mytable WHERE price = theprice DESC LIMIT 1;
