OLAP analysis could reveal the root cause as an inexperienced manager who works in both of the problem stores.

What are the functions of OLAP?

Common Functionality of OLAP Tools 1 Drill-down is used to present more granular detail about a given variable. The company in the example above may wish to focus in on sales of a particular brand’s products. Using a drill-down function, they could de-aggregate the sales-per-brand totals above to learn which items from an individual brand have sold in what quantities. 2 Slice-and-dice lets users look at the business’s datasets from different angles and perspectives. In the above example, the department store might want to correlate sales to a variable other than the individual salesperson or their selection of brands. For example: They might want to know how the number of salespeople working during a single shift across all branches affects sales of one particular brand. The slice-and-dice functionality of OLAP tools makes that possible. 3 Roll-up is the opposite of drill-down, and the two are often used in conjunction. Roll-up combines data into broader categories, decreasing the level of detail. In the slice-and-dice example above, the store might roll-up the per-branch sales information before further analysis, given that they’re not concerned with that variable for this analysis.

How does OLAP work in a department store?
