How to Effectively Realize Data


Published on

Organizations are inundated with data – terabytes and petabytes of it. Data pours in
from every conceivable direction: from operational and transactional systems, from
scanning and facilities management systems, from inbound and outbound customer
contact points, from mobile media and the Web. It is structured and unstructured; it is
messy and overwhelming; it flows at greater speed than ever.
The optimist’s vision for this tidal wave of data is that organizations will be able to harvest
and harness every relevant byte of it to make supremely informed decisions.
However, traditional architectures and infrastructures are not up to the challenge. IT
teams are burdened with ever-growing requests for data, ad hoc analyses and oneoff
reports. Decision makers become frustrated because it takes hours or days to
get answers to questions, if at all. More users are expecting self-service access to
information in a form they can easily understand and share with others.

To see a video demo of“Many challenges arise when working with this much data,” said Justin Choy, Global SAS® Visual Analytics:Product Manager for Business Intelligence Solutions at SAS. Choy joined Jennifer of SAS Business Intelligence Product Marketing for a webinar in the SAS watch?v=1DUM4YdnzzAApplying Business Analytics Series. “One problem is that it takes a long time toaggregate all that data. To get around this problem, IT has to create summaries of the Related white papers:data, or a cube with predefined hierarchies for better performance.” Big Data: Harnessing a Game-Changing Asset“Once you have a summary or a cube of the data, you can look at it more quickly,” said “But what happens when you realize you need to look at the data in a differentway than the summary or cube provides? You would typically have to turn to a data In-Memory Analysis: Deliveringadministrator or someone else in IT, and request another view of the data.

Running on low-cost, industry-standard blade servers using Hadoop distributed processing, it delivers answers in access more than a billionseconds or minutes instead of hours or days. This kind of processing speed with rows of data, and then verymassive data sets makes it possible to find important insights quickly – insights that quickly explore all of that datawere not evident before. using visualization techniquesFor example, marketing campaign optimizations that previously took eight to 10 hours combined with powerfulor more can now run in less than three minutes.

They can apply sophisticated analytictechniques, not just simple calculations, to generate descriptive and predictive insightsfrom all that data. And they can put this power into the hands of a broad range of usersthrough a dynamic, visual interface.Consider some possibilities.

This processing power is coupled with SAS Analytics,which differs from other solutions that simply move data from a SQL database intomemory. Other solutions cannot support regressions or logistics models because suchcapabilities are not built into databases. 3
  6. 6.

I can double-click on the bubble and go into thatregion for more detail. It’s as simple as that, and all of the data being presented to meis based on a billion rows of geographic, product and financial information forthis manufacturing company.”Figure 1: The interface uses intuitive, drag-and-drop actions and visualizations.4
  7. 7. How to Effectively Realize Data VisualizationCreate Your Own HierarchiesIf you need the data organized a certain way for the business problem at hand, youdon’t have to go to your company’s data specialists to request a new view of the data.“With SAS Visual Analytics, you have access to all of the data, and based on all of thedata, you can create and modify your own hierarchies to explore the data, however andwhenever you want, without having to rely on someone else,” said Choy.“It is so easy to do. I can create a new visualization and then go into the ‘Create a New Build-it-yourself hierarchiesHierarchy’ area, and then just double-click or drag and drop [from a menu selection box]the items on which I want to build a hierarchy. Once I’m satisfied with that, I can give it a eliminate the need for dataname or just hit ‘OK.’ It’s that easy.” analysts to constantly seek help from IT.

All of these views are changing within seconds, yet slice and dice data on any level.drawing on a billion rows of data behind the scenes.Choose the Best Visualization for the Data“When you’re working with a billion rows of data, it is really difficult to quicklyunderstand what’s happening in the data simply by looking at rows and columns,”said Marchi. “Even guessing what type of chart to use can be challenging. SASVisual Analytics simplifies all that by using intelligent autocharting to recommend anappropriate type of visual for the information you’re trying to view. It could be a line orbar chart, a scatter plot or box plot, heat maps or bubble charts – anything from theportfolio of available visualizations.” Autocharting capabilities helpIn the example shown in the demo, SAS Visual Analytics recognized that the data had users create the best possiblegeographic elements – revenue and expenses by geographic regions – and offered the visualizations, including thosedata as a bubble plot superimposed on a map of the regions. In another example, Choy specifically designed to displayshowed how SAS Visual Analytics chose a line chart as the best visual for a selection of big data.two variables, then changed to a clustered bar chart when a third variable was added.Of course, users can always select the desired of visual – anything acceptable to themeasures and categories chosen.And remember, this speed-of-sight display is being calculated with 1.1 billion rowsand 47 columns of data. 5
  8. 8. SAS Conclusions PaperRefine the ViewWhat if you only want to view data for a certain region, product line or some othervariable? “SAS Visual Analytics has filtering capabilities that make it easy to refine theinformation you’re viewing,” said Marchi. “Simply add a measure to the filter pane orselect one that’s already there, and then select or deselect the items on which to filter.”What if the filter isn’t meaningful, or it skews the data in undesirable ways? A histogramon the right of the screen provides a visual cue about the distribution of the data,showing how the data is affected by filtering a particular measure, said Marchi, whoused expenses as an example. “The histogram shows that the majority of the data ison the left, so if I filter from the right, it will have a minimal impact on the informationI’m viewing in the visualization pane. However, if I filter from the left, it will have a moresignificant effect on what I’m viewing, because the majority of the data is distributed inthis area. Histograms allow you to save time by giving you an idea what effect the filterwill have on the data before you apply it. Rather than relying on trial and error or gut feel,you can use the histogram to help you decide what areas to focus on.”Understand the Distribution of the DataUnderstanding the distribution of the data is now as simple as creating a new visualand dragging the measure or category onto the visualization pane.“By default, the system automatically calculates the best distribution for the data, butthe user can go under the ‘Properties’ tab and change that,” said Choy. “A histogramshows how the data is distributed, but a better visual for this purpose is a box plot[which graphically depicts numerical data through summary calculations such asminimum, maximum, upper and lower quartile, and median]. I can create a new box plotby creating a new visualization, selecting that visual, and then dragging and droppingthe visual on here. You can hover over the box plot and not only see the distribution ofthe data, but also where the important 50 percent of your data is, as well as some basicstatistics about the data, such as average, median, standard deviation, minimum andmaximum, average standard deviation, whisker and quartiles information, and count.“I can even add a new measure onto here, and we can do a comparison over twodifferent measures in the box plot. I can then add another category in here, such asproduct line, for example, and now instead of doing 10 calculations on the fly, we’reactually doing 40 calculations over a billion rows. And we’re getting the results extremelyfast, especially considering that the median, the middle value of the data, requiresscanning all 1.1 billion rows of data.”6

No problem. “For business users or analysts who are not familiar with terms suchas ‘regression’ or ‘correlation,’ help is available,” said Marchi. “We’ve added a ‘WhatDoes It Mean’ feature to explain some of the terminology and help users understandwhat they’re seeing.” Click on the information icon, and a pop-up dialog box explainswhat the analysis has shown: for instance, that there is a correlation of -0.94, whichsuggests there’s a strong linear relationship between two variables. 7
