Dickeson--Give Poor Roger's OLAP a Look

Let me use a personal example to illustrate. I've maintained a database of web printers for nine years. It's a "relational" database consisting of four tables or files. Table One is for companies. Each company has an ID, a number that identifies it. Table Two describes the dozen or so products that presses produce. Table Three details the presses, their IDs and the IDs of the companies operating them, as well as product IDs. Lastly, there's a "transaction" file: Companies send me monthly operational data for their presses, and I enter a record for each press, including the ID numbers of the company and the press, as well as the data for time intervals and impressions.
