Data is captured and stored for a variety of reasons. Hours beyond count (and even more budget) invested in collecting, ingesting, structuring, validating, and ultimately storing of data; to say that it is a valuable asset is to drive home a moot point. This day in age it may, in fact, be our most precious commodity.

Some data is used strictly as an archive. Perhaps to record or track events that happened in the past. But the other side of that coin is that historical data has value in basing decisions for the future and future endeavors.

• What day to have our sale on? (Planning for future sales based on how we did in the past.)
• Which salesperson performed the best in quarter one? (Looking back, who can we reward for their efforts.)
