Drilling-down & Rolling up
Drilling-down is the process of zooming in on data at lower level, thus seeing the members that make up the current value. Rolling-up is the inverse of drilling-down. Drilling-down and rolling-up is made simple within the DWE: when it is possible to drill-down a plus sign '+' will appear next to the item. By clicking this sign you will drill-down on the results. When a roll-up is possible, a minus ‘-‘ sign will appear next to the item. This is analogous to a folder tree in the windows explorer.
Slicing
Slicing data is the process of setting the context of the information you are viewing. E.g., you can view the sales per customer in the context of the year ‘2006’ for products ‘A’ and ‘B’. Setting the context is easy in DWE, just select the hierarchy for which you want to include in the current context a check the desired items.
Filter
You can filter your results to leave out or only include values that meet certain conditions. E.g., you can filter the results to only show the top or worst 10 customers for product ‘X’, or only show the products that generate profit instead of loss. Filtering can be achieved by simply clicking on the column header of the column on which you want to filter and defining the filter conditions.
Statistics
You can add extra rows and columns to the grid that contain statistical calculations based on the results. These statistical calculations include total, average, count, minimum, maximum, standard deviation and variance. There are also "smart" statistics that avoid counting duplicates.
Sort
You can sort your results by simply clicking the title of the column on which you want to sort. Just as you would expect.
Columns can be sorted with or without loosing the hierarchy. Sorting without the hierarchy means that all values in the column are sorted without looking at the hierarchy. All values in all columns have been sorted from small to large. Sorting with the hierarchy means that within a certain level all rows are sorted.
Calculated member
A calculated member is a dimension member whose value is calculated at run time using an expression that you specify. Many templates are available from which new calculations can be created, including common business calculations (totals, %difference, ratios, etc.), period comparisons (ytd cumulative, change from last year/period, change from last year period in %, etc.), distinct count with basket analysis and statistical calculations (averages, standard deviation, variation, maximum, etc.).
