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.

The essence, art & science of effective data story telling via Microsoft Power BI

It has been some time since I have really focused in on technical writing, relating to my career. For those that do not know I was a Microsoft MVP for Microsoft Dynamics AX for three years. That came from speaking at events like AXUG Summit, what was once called Microsoft Convergence and other such events like Focus, and so on and so forth. The real 'claim to fame' if any could be attributed to me, was found in my blog focused around all things Microsoft Dynamics AX. That is still up, though the supporting content long gone now. (For reference, that older blog was: http://dynamics-ax.blogspot.com). Here now sitting out some five years from retiring that blog I have wanted to get back into my serial writing habits. I will be the first to admit that it has been hard to have clarity of focus around specific topics of value.  Such topics that I would like to know more about and target with getting back to adding my voice into the community at large. With that I set off to create this site, GoPowerBIPro.com and its sister site, currently under construction Oppia.co. The sister site is really the essence of renewed focus I have that will be driving the content on this site and Oppia.co as well. The word Oppia is a Finnish word that translates into English: "Learn". And that is exactly what the two sites are meant to enable. To help the larger community learn through my ramblings, rants and full register of idea's.

Oppia - Finnish word that translates in English to Learn
With that the singularity in which this blog will focus as been honed and established. That focus then is to help others learn effective data story telling capabilities. Each post then has that essence built into its core and content. (more…)
