Datawarehouse

The arrival of the modern data warehouse – part i

One of the cornerstone technologies for enabling enterprise grade insights is the data warehouse. This has had many names adopted through the years, since the inception of the phrase itself by no other than Bill Inmon. (resource: Find out more on our resource page) Having coined said phrase back in the 1970's, with the goal in crafting a standard in which a companies data could be stored, accessed and used in order to provide a single source of truth in which describes and tell the story of said company. Thus the great data warehouse religious wars began that pitted two strong willed and minded camps. Those whom would embrace the original author of the concept itself found themselves flying and fighting for the Inmon camp. With this there was yet one more knight in which to battle until victory was claimed. If therefore you where not part of the Inmon camp then you found yourself digging in and amazed at the fact in which anyone would design for a company the construct that a data warehouse represents - no others than that of Ralph Kimball's approach to the design of the coveted single semantic layer. This, as time progressed onward, would then in turn be called an enterprise data warehouse. Inferring with its name the single and solely accepted version of a companies truth, and that Kimball on a tone of 7/8-1 would be used in designing a companies prized semantic layer.
