Retroactive, ranges, forecasting, etc. This functionality is crucial for various applications, including: E-commerce platforms: Retrieving sales data for specific periods.
We keep on piling workarounds, each more ridiculous than the last, on top of a design that is pretending to be eternal, but failing. What benefits do you get by properly expressing this data in an Effective Dating scenario?.
By inserting rows of data based on his. To get the current row you need to find the maximum effective dated row, and then the maximum effective sequence for that effective date. But simply stated, what exactly is the problem with Date/Time data and why is it so complicated?
How an organization applies it will be the same across domains; yet, which objects it leverages against will be their business revenue generator. The Concept Although we don't always express this in our database schemas, most data is temporal; it actually only lives over a period of time.
