Dickeson--Give Poor Roger's OLAP a Look

It's a "rationalized relational database" set up for OLTP. Each transaction record is "related" to a company, a press and a product.

Know What to Know
It's easy to enter transaction data each month: I don't have to repeat a string of data for each company, press and product. Nor do I use up a lot of disk storage space or "read" time for the disk drive heads. I publish structured reports using special report-writing software that "joins" the tables using the ID number relationships.
