hi pc_melsa,

? seemed to be a misunderstanding

a tdecisioncube is for querying data from a database and for calculating values like average or sum or max from the queried data. normally its used to visualize a compressed view of the queried data with the capability of drill down to base data.

its not used for storing data into a database, only retrieveing data, compressing in a given manner (aggregat-function) and grouping for visualizing the data on a form.

sample
we've an orderdatabase with customers and orders.
the user will now see the sum of orders from the customers about one year.

we do now query orders between a date and sorting it by customerid, maybe we join the query with the customer-table to get the name into the query-result.

in the decisioncube we define to show first, the sum-value of orders for each customer. with a bit adjustments we can allow that the user can show by doubleclicking on a customer the monthly ordervalue of that customer and by doubleclicking of a month he could get the order of this month of this customer.

therefore a decisioncube is visualizing-tool for much detaildata, with the capability to show the amount in a compact manner and  to drill down to the detaillevel in defined steps.

hope this will clarify the use of tdecisioncube,
otherwise rephrase the question
