1 1 2 3 4 1 2 3 4 A B D C G5b Date 1Qtr 2Qtr 3Qtr 4Qtr TV Product PC U.S.A VCR Canada Country Mexico A Sample Data Cube Each cell contains a sales measurement, e.g., the number of sales (may contain many other measurements of product-date-country instances)

2 Total of all product sales by country and quarter
Total sales by country and date Rollup (aggregate under +) along product (e.g., using the aggregate, sum) Date 1Qtr 2Qtr 3Qtr 4Qtr TV Product Total of all product sales by country and quarter PC U.S.A VCR Canada Country Mexico

3 Rollup along date (e.g., using the aggregate, sum)
Total annual sales by country and product Date 1Qtr 2Qtr 3Qtr 4Qtr TV Product PC U.S.A VCR Canada Country Mexico

4 Rollup along country (e.g., using the aggregate, sum)
Date 1Qtr 2Qtr 3Qtr 4Qtr TV Product PC U.S.A VCR Canada Country Mexico Total of all product sales by product and date Total of all product sales by product and date

5 All rollups (e.g., using the aggregate, sum)
Date 1Qtr 2Qtr 3Qtr 4Qtr TV Product sales by product, country PC U.S.A sales by product, country and quarter VCR sales by country, date sales by country sales by country Canada Country Mexico sales by product sales by product, country sales by product sales by date sales by date Total sales Total sales Total sales

6 Cuboids Corresponding to the Cube
all 0-D(apex) cuboid product date country 1-D cuboids product,date product,country date, country 2-D cuboids Drilldown on product product, date, country 3-D(base or fact) cuboid Rollup on country (Sum over country)

7 Date 1Qtr 2Qtr 3Qtr 4Qtr Product TV U.S.A non-comp comp VCR PC Canada Country Mexico Partial Rollup: climbing up a concept hierarchy (instead of eliminating Product altogether by summing over all products, rollup partially on Product, from (VCR, PC, TV) to computer (includes PC only) and non-computer (includes VCR + TV)

8 SLICE e.g., slice off PC Date Product Country 1Qtr 2Qtr 3Qtr 4Qtr TV
