Today, the world is trying to create and educate data scientists because of the phenomenon of Big Data. And everyone is looking deeply into this technology. But no one is looking at the larger architectural picture of how Big Data needs to fit within the existing systems (data warehousing systems). Taking a look at the larger picture into which Big Data fits gives the data scientist the necessary context for how pieces of the puzzle should fit together. Most references on Big Data look at only one tiny part of a much larger whole. Until data gathered can be put into an existing framework or architecture it can't be used to its full potential. Data Architecture a Primer for the Data Scientist addresses the larger architectural picture of how Big Data fits with the existing information infrastructure, an essential topic for the data scientist. Drawing upon years of practical experience and using numerous examples and an easy to understand framework. W.H. Inmon, and Daniel Linstedt define the importance of data architecture and how it can be used effectively to harness big data within existing systems. You'll be able to: - Turn textual information into a form that can be analyzed by standard tools. - Make the connection between analytics and Big Data - Understand how Big Data fits within an existing systems environment - Conduct analytics on repetitive and non-repetitive data - Discusses the value in Big Data that is often overlooked, non-repetitive data, and why there is significant business value in using it - Shows how to turn textual information into a form that can be analyzed by standard tools - Explains how Big Data fits within an existing systems environment - Presents new opportunities that are afforded by the advent of Big Data - Demystifies the murky waters of repetitive and non-repetitive data in Big Data

Corporate Data


Abstract


Corporate data includes everything found in the corporation in the way of data. The most basic division of corporate data is by structured data and unstructured data. As a rule there is much more unstructured data than structured data. Unstructured data has two basic divisions – repetitive data and nonrepetitive data. Big Data is made up of unstructured data. Nonrepetitive Big Data has a fundamentally different form than repetitive unstructured Big Data. In fact the differences between nonrepetitive Big Data and repetitive Big Data are so large that they can be called the boundaries of the “great divide.” The divide is so large many professionals are not even aware that there is this divide. As a rule nonrepetitive Big Data has much greater business value than repetitive Big Data.

In today’s world it is easy to get lost when dealing with data. There are many different types of data and each type of data has its own peculiarities and idiosyncrasies. Products, vendors, and applications become so focused on their own specific world that the larger picture of how things fit together often gets lost. It oftentimes is useful to step back and look at the larger picture to gain a proper perspective.

The Totality of Data Across the Corporation


Consider the totality of data found in the corporation. A simplistic depiction of the totality of data found in the corporation is seen in Figure 1.1.1.
Figure 1.1.1 
The totality of data represented here includes everything to do with data of any kind found in the corporation.
There are many ways to subdivide the totality of data in the corporation. One such way (but hardly the only way) to subdivide the data found in the corporation is to divide the totality of data into structured data and unstructured data, as seen in Figure 1.1.2.
Figure 1.1.2 
Structured data is the data that has a predictable and regularly occurring format of data. Typically structured data is managed by a database management system (DBMS) and consists of records, attributes, keys, and indexes. Structured data is well defined, predictable, and managed by an elaborate infrastructure. As a rule most units of data in the structured environment can be located very quickly and easily.
Unstructured data, conversely, is data that is unpredictable and has no structure that is recognizable to a computer. As a rule, unstructured data is rather clumsy to access, where long strings of data have to be sequentially searched (parsed) in order to find a given unit of data. There are many forms and variations of unstructured data. Perhaps the most commonly occurring form of unstructured data is text. However, by no stretch of the imagination is text the only form of unstructured data.

Dividing Unstructured Data


Unstructured data can further be divided into two basic forms of data – repetitive unstructured data and nonrepetitive unstructured data. As is the case with the division of corporate data, there are many ways to subdivide unstructured data. The method shown here is but one of many ways to subdivide unstructured data. This simple subdivision of unstructured data is shown in Figure 1.1.3.
Figure 1.1.3 
Repetitive unstructured data is data that occurs many times, often in the same structure and even in the exact same embodiment. Typically, repetitive data occurs many, many times. The structure of repetitive data looks exactly the same or substantially the same as the previous record. There is no massive and elaborate infrastructure managing the content of repetitive unstructured data.
Nonrepetitive unstructured data is data where the records are substantially different from each other. In general each nonrepetitive record is markedly different from each other record.
The division of data types in the corporation has many different embodiments. Consider the data as shown in Figure 1.1.4.
Figure 1.1.4 
Structured data is typically found as a by-product of transactions. Every time a sale is made, every time a bank account encounters a withdrawal, every time someone transacts an ATM activity, and every time a bill is sent a record of the transaction is made. The record of the transaction ends up as a structured record.
Unstructured repetitive data is quite different. Unstructured repetitive records are typically records of machine interactions, such as the analog verification of product coming off a manufacturing process or the metering of energy usage by a consumer. Consider metering. There is great repetition of records in both form and substance that are created when looking at metered readings.
Unstructured nonrepetitive information is fundamentally different than unstructured repetitive records. With unstructured nonrepetitive records there is little or no repetition of either form or content from one record to the next. Some examples of unstructured nonrepetitive information include email, call center conversations, and market research. When you look at one email, the odds are very good that the next email in the database will be different than the previous email. The same is true for call center information, warranty claims, market research, and so forth.

Business Relevancy


Unstructured repetitive data and unstructured nonrepetitive data have very different characteristics, in many different ways. One of the ways that these two types of data are different is in terms of business relevancy. In unstructured repetitive data, there often are very few records that are of real business interest. With unstructured nonrepetitive data, however, there is a very large percentage of business-relevant data.
This difference between the two types of data is shown in Figure 1.1.5.
Figure 1.1.5 
As an example of a small percentage of repetitive unstructured data being business relevant, consider the millions of phone calls that are made each day. The government is only interested in a very few phone calls out of the millions that have been made. Or consider manufacturing control information. Nearly all manufacturing records are not of interest. Only a very few records – usually where the parameters being measured exceed a threshold – are of interest. Oftentimes with unstructured repetitive records, there are records that are not directly or immediately of interest but are potentially of interest in this category.
There are not too many records that are not of interest when it comes to unstructured nonrepetitive data. There is spam and there are stop words. But other than those two categories of information, nearly all unstructured nonrepetitive data is of interest.

Big Data


It is of interest to note that Big Data consists of the unstructured repetitive and the unstructured nonrepetitive data in the corporation, as seen in Figure 1.1.6.
Figure 1.1.6 

The Great Divide


At first it may seem that the differences between the two types of unstructured data – unstructured repetitive and unstructured nonrepetitive data – are almost whimsical or trivial. In fact the differences between the two types of unstructured data are anything but trivial. Because of the profound differences between the two types of data, there is a great divide that separates the two types of unstructured data.
Figure 1.1.7 shows the great divide that separates the two types of unstructured data.
Figure 1.1.7 
The great divide that separates the two types of unstructured data occurs because data on one side of the divide is handled one way and data on the other side of the divide is handled in an entirely different manner. For all practical purposes the data found on the different sides of the great divide might as well exist on different planets.
The division in the way that data is handled is such that unstructured repetitive data is almost entirely consumed with a fixation on managing Hadoop. For unstructured repetitive data the emphasis is entirely on accessing, monitoring, displaying, analyzing, and visualizing data residing on a Big Data manager such as Hadoop.
The emphasis on unstructured nonrepetitive data is almost entirely centered on textual disambiguation. The emphasis here is on the types of disambiguation, the reformatting of the output, the contextualization of the data, the standardization of the data, and so forth.
The remarkable thing about the great divide is that the disciplines surrounding the data are so diametrically different. Textual disambiguation is a very different subject than the access and analysis of data stored on Hadoop. It is because of the extreme differences between these two worlds that it is said that the two worlds live in different planets.
To use an analogy to illustrate just...
