Startup Idea : Service for Split Testing DB values

I have not find such service yet. Main focus here is that you can split test DB's records with no effort,development,... Split testing of values from DB is important as there are stored important values like prices,discounts .... . I think it can be a web service.Customers can integrate it with using the API and split test desired records with multiple values and understand whats going on.It will also has admin page where you can define desired variations of a record and also will have tracking and nice charts for viewing them.
