Please check your browser settings or contact your system administrator. Obviously, the value of that barrel of high-octane fuel would be worth more than the 16.9x the value of the raw oil.  In fact, that barrel of high-octane fuel that never depletes, never wears out and can be used over and over again across an unlimited number of use cases would likely have infinitevalue.

Book 2 | However, understanding the “economics of oil” starts by understanding the differences between raw oil and refined fuel. Forcing every analytic use case or application to curate its own data is not only not very user-friendly, but it dramatically reduces the value of the data to the organization.  If we really want to serve the organization’s “consumers of data”, we need a methodical process for refining, blending and engineering the raw data into something of higher value – “curated” data. Let’s study about raw data, classification of data and variables. The “Economics of Data” is an even more powerful conversation when trying to contemplate the business and operational value of “curated” data versus “raw” data, Making every analytic application curate its own data is the same as forcing every car to refine its own oil. Book 1 | Here, each class represents a range of numerical values for the phenomenon under consideration. As it is classified into classes with a different range of values, this classification is effectively the representation of the change of the value of a phenomenon over time or across different regions. In other words, a variable is a characteristic or a phenomenon which is capable of being measured and changes its value over time. A single source of raw data in California.

Figure 1: Refining raw oil into more valuable racing fuel. •       Data Indexing and Re-indexing. “Curated” data is raw data that has been gathered, cleansed, aligned, normalized, enriched with metadata and is cataloged, indexed and governed to ensure its proper usage. Leading organizations today are trying to weave raw data into business gold by understanding and exploiting the economic value of data. Again, the phenomenon should be such that it can be expressed in numerical terms. But it is really expensive, not affordable for everyone. Data experiences the same economic transformation as oil.  Raw data needs to go through a refinement process (cleanse, standardize, normalize, align, transform, engineer, enrich) in order to create “curated” data that dramatically increases the economic value and applicability of the data (see Figure 4). The centralized data repository allows the public & researchers to find, use, and repackage the volumes of data generated by the State. Raw crude oil goes through a refinement, blending and engineering process where the crude oil is transformed into more valuable products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, liquefied petroleum gas, jet fuel and fuel oils.  This is a critical process that needs to be performed before the downstream constituents (like you and me and industrial concerns) can actually get value out of the oil (as gasoline or heating oil or diesel fuel).  Oil in of itself, is of little consumer or industrial value.  It’s only through the refinement process that we get an asset of value (see Figure 2).

A variable is classified into two: A discrete variable’s value changes only in complete numbers or increases in jumps. Obviously, the value of that barrel of high-octane fuel would be worth more than the 16.9x the value of the raw oil.  In fact, that barrel of high-octane fuel that never depletes, never wears out and can be used over and over again across an unlimited number of use cases would likely have, Maybe the right analogy isn’t the Brothers Grimm story of “, ” but is the Brothers Grimm story of the “.

And this is exactly what we do in Information Technology; we give our users access to the raw data and force each use case or application to have to go through the data refinement process to get something of value (see Figure 3). Raw data is a term used to describe data in its most basic digital format. we cannot measure an attribute in quantitative terms like 5, 1, 2 etc. But we require inference of the data given to us.

A variable is simply something that can vary with time and we can measure this variation. That’s when the classification of data saves the day! The classified data has following advantages over the raw data. Data is replicable. To create value out of oil, oil must first be refined.  For example, when raw oil (West Texas Crude) is refined into high-octane fuel (VP MRX02 high-octane racing fuel), the high-octane fuel is 16.9x more valuable than the raw oil[1](see Figure 1).
