Junk Viz - When More is Less

There are examples of junk visualizations, and then there are examples of junk charts that just take your breath away.

The Indian news portal,, which describes itself as a "trusted guide to the crush of news and ideas around you", published a story titled Shivraj set for massive victory in Madhya Pradesh: Survey | Firstpost, which has this chart (link to the image) - take a minute to study it. Then study it again. It is no optical illusion or card-trick being played here.

HBR and Junk Charts

Even the best can get it wrong. Only sometimes though, one hopes.
The venerable Harvard Business Review gets data visualizations horribly wrong. They have a post on Facebook where they contrast the costs of cancer treatment in the US and India.

The cost in the US is $22,000 on average, while in India it is shown as $2,900 (I would dispute this figure, as it looks very low).
The ratios is 7.58:1 (22000÷2900)

BI Mobile HD App

Finally got around to writing my long overdue post on the new BI Mobile HD app. To get on with it, without much ado, not to loiter, and all that... here goes.

The new BI Mobile HD app, version, can be downloaded from the Apple iTunes App Store (link to app preview page on iTunes).
If you already have the BI Mobile HD app installed on your iOS device, you should get an App Store notification on the availability of an upgrade. Note, that since this version is available only for iOS version 6 (and above), if you are running an older version of iOS, you will not get a notification, and will not be able to download it. If you check the Wikipedia iPhone page (link) you will see that the iPhone 3GS and later devices support iOS 6. As far as the iPad device goes, if you check the Wikipedia page (link), iPad 2 and later devices support iOS 6.

Creating your first app with the BI Mobile App Designer

While creating sophisticated mobile apps that provide a rich feature set takes time, expectedly, what is wonderful about the recently launched Oracle Business Intelligence Mobile App Designer is the fact that you can be up and running without requiring a week-long training and a Master's degree in Computer Engineering.

Here's a short video I recorded on creating your first app with the BI Mobile App Designer (the direct URL on YouTube). A note of caution, and an apology of sorts - the audio in last few seconds of the video dramatically jumps up in volume. This is because I recorded these last few seconds later, and used different audio settings. I should have normalized it. I live, and I learn.

Introduction to the BI Mobile App Designer

Oracle launched a brand new addition to its Business Intelligence Mobile solution - BI Mobile App Designer, which lets you create stunning, interactive mobile apps, literally within minutes. Apps created run on mobile devices running a reasonably modern mobile browser - that can handle HTML5 and jQuery - and are available on both smartphone and tablet form factors.

White spaces and Map Views

When working with Map Views, you can choose to collapse the map formats panel on the left.

When you do that, the panel is hidden, but white space is displayed on either side of the map view, where the panel used to be.

Currently there is no option to remove this white space through a UI setting.

Using R to Unlock the Value of Big Data, by Mark Hornick

Using R to Unlock the Value of Big Data, by Tom Plunkett, Mark Hornick

This is a brief (approximately 80 pages) introduction targeted at users with an intermediate-level exposure of R and who want to get a quick look at working with R with Oracle's products. Strictly speaking, this is not an introduction to R, nor is this an R tutorial. It is, very specifically, an introduction to R as it integrates with and relates to the Oracle Database, the Oracle R Distribution, and the Oracle R Connector for Hadoop. The main chapters are "Using Oracle R Enterprise" and "Oracle R Connector for Hadoop", which have sixteen and seventeen examples, respectively, to help you get started.

Lying with Charts - Global Warming Graph

Global warming is a serious yet controversial enough topic without bringing in bad data visualizations practices into it. The Wonkblog on the Washington Post has an article titled, "You can’t deny global warming after seeing this graph". The post reproduces a chart prepared by the World Meteorological Association that plots global temperatures by decade. While the data shows that the last decade, 2001-2010, was the hottest on record, the graph uses a broken Y-axis that begins at 13.4°C instead of starting at zero. The chart does not hide this fact, and you can see that the chart's Y-axis starts at 13.4°C, but the most visually prominent piece in the graph is, well, the graph! And it screams the message that global temperatures are going off the charts - it's time to panic. There is no denying that we as a world need to get serious about investing in alternative and renewable sources of energy like solar, wind, and even nuclear, but this graph is just plain bad.

BI Mobile HD Universal App Released

A new version ( of the Oracle BI Mobile HD App was released to the Apple iTunes App Store on Wednesday. This release has several new features of note. This updated version also fixes some issues that were reported in the update that went out late last week on the 28th of June.

  • All users are recommended to upgrade to this version of the BI Mobile HD app. There were login issues with the iPad version of the earlier app and orientation issues with the iPhone app. Both issues were noticed almost immediately after the app went live on the App Store and development traced these to a problem with the configuration of the app uploaded to the App Store. 
  • Users will notice that this is app now supports the iPhone (and iPod) device also. Therefore users will see this app on their iPhone when they search for it on the App Store.

OBIEE Certified with Database 12c

Couple of updates in the world of Oracle, both related. The first is that the Oracle Database 12c is now generally available and can be downloaded from the Oracle Technology Network here (subject to the OTN Developer License Terms). Three platforms are supported - Linux x86-64, Solaris Sparc64, and  Solaris (x86-64).

You may want to take a look at the Plug into the Cloud with Oracle Database 12c White Paper. Coincident with the release, there is a series of events being organized. You can find one in your city or near it at Oracle Database 12c | Oracle Technology Day page.
The first place to begin to learn about this new release is of course the documentation library. Specifically, you should have the 2 Day DBA, 2 Day + Security Guide, the New Features Guide, and the Concepts guide bookmarked. I have, and my summer plan (monsoon plan here in India) is to go over these books.

The documentation library is also dedicated to the memory of Mark Townsend, who passed away unexpectedly in April 2012.
Contributor: The Oracle Database 12c documentation is dedicated to Mark Townsend, who was an inspiration to all who worked on this release.

The second update is that the Oracle Fusion Middleware Supported System Configurations page has an updated System Requirements and Supported Platforms for Oracle Business Intelligence Suite Enterprise Edition 11gR1 matrix for, which now includes Oracle Database 12c as a supported database. Specifically, Oracle Database version and above are now supported with Oracle BI EE only. This certification does not extend to older releases of Oracle BI.

Oracle BI and Endeca Certification

This is a very short post, and meant to clarify a point of potential confusion.

The recently released Oracle BI EE release features integration with Oracle Endeca Information Discovery, both for use as a search engine and as a data source in BI Publisher.

However, this integration is for version 2.4 of Endeca Information Discovery (doc, download). Support for the recently released version 3.0 (doc, download) is planned and not yet available. 

I will post an update as and when I have more information to share.

BI Mobile App Update

An update to the Oracle Business Intelligence Mobile HD app went live on the Apple iTunes App Store. This is the version of the app, and if you already have the Oracle BI Mobile HD app installed on your iPad device, you would have been notified via the App Store app (kind of redundant isn't it - calling it the "app" store "app"?) of the available upgrade.

As far as updates go, this version basically brings in bug and stability fixes, along with two minor enhancements. First, you can now change between landscape and portrait orientation when viewing content, and second, you can now send content as PDF attachments via email.

A new option on the "Settings" screen - "Display" - has been added to let users control how attachments should be displayed when sending them via email - "as Links", "as Attachments", or "as Inline". The "as Links" option basically means no attachment is included with the email, and only links to the content are included in the body of the email. The "as Attachments" option, when selected, adds a sub-option to the "Settings" screen, named "Format", which lets you select whether format of the attachments should be "PDF" or "HTML". The third option - "as Inline" - embeds the content inside the body of the email as rich HTML.

That's all folks.

Enterprise Analytics Book - Review

I was somewhat excited and was looking forward to reading this book, given that it firstly is on my area of work at Oracle - enterprise analytics, secondly because it covers an important, growing, and still nebulous area of both the technology and business of Big Data, and thirdly, because the author is a very well-respected authority on the field and who shot to wider fame with his now famous 2007 article in the Harvard Business Review, "Competing on Analytics". With this preamble, I submit to you, my review of the book, "Enterprise Analytics: Optimize Performance, Process, and Decisions Through Big Data (FT Press Operations Management)", Thomas H. Davenport, et al.

"Lectures, Meanders, Pontificates, But Does Not Educate"
(AmazonMy Amazon review, Kindle US, Amazon UK, Kindle UK, Flipkart)
Or, how a book on Big Data, Enterprise Analytics, and technology can neatly skirt any meaningful discussion of Big Data, Enterprise Analytics, and technology.

While a few chapters stand out for their reasoning and clarity, what is jarringly absent from this book is any meaningful, technical discussion about Big Data itself. Without such a discussion, most of the book's content can be recycled with minimum effort ten years from now and applied to the next big thing in technology. Even assuming that this book is targeted at decision makers and so-called C-level executives, an absence of the nuances and complexities of Big Data mean that executives will be as clueless on that dimension of Big Data knowledge after reading the book as before. If you are responsible for selling sausages, you had jolly well get a look at the sausage factory, if not work there a day.

Big Data, Unstructured Data, the Cloud - if these three buzzwords were not enough, you can add the salsa-ish phrase SoLoMo - i.e. Social, Local, and Mobile, to the mix. Businesses, consultants, enterprises, anyone who is anything in technology wants to know more about what this buzzword alphabet soup is, and how to make sense of it before their competitor does, or worse - a disruptor.

The hope is that if the decision makers, the corner-room occupiers can understand this, they will be better able to drive a coherent process and structure within their organizations to take advantage and benefit. Hence this book.

The book is a collection of eighteen chapters, divided into five parts - the first is an "Overview", "Application", "Technologies", "Human Side", and "Case Studies" of Analytics. Each chapter is written by a different author, with a total of fourteen authors in the fray. A few chapters have been written by the editor himself, Thomas Davenport, and these are among the standout chapters - for their clarity and organization.

Since I work in the technology of analytics, I should be excused for either taking too technical a view of things, or for being too harsh in my criticisms. Having said that, there are at least quibbles that in my opinion leave this book only a middling, mediocre effort, and not one that will be remembered or consulted, much, if at all.

- The close and financial collaboration of at least a few technology vendors with the International Institute of Analytics means that most of the specific examples cited in this book are where the technology vendor's solution was used. Fair enough, but it leaves an aftertaste of an advertorial in the reader's mind.

- When discussing web analytics, there is a lot of ink devoted to the topic of "page views". Page Views are still relevant, but they are becoming increasingly obsolete in the world of AJAX - where parts of a page and its contents can be updated without having to reload the entire page. Web analytics metrics operate at the least granular level of pages, and hence cannot capture a significant chunk of user interactions and engagement that occur on pages and sites that make heavy use of such asynchronous page content refreshes (AJAX does stand for "Asynchronous JavaScript and XML", and no - it does not contain the buzzword "Agile"). More sophisticated measures of user engagement are being built that track more than simple page views. When the chapter's author fixates on page-views without once mentioning the inaccuracies of measurement that AJAX can inject, the credibility of the chapter suffers.

- The chapter on "NBOs", i.e. "Next Best Offers" takes several cheap shots at Amazon (see page 90), which left me wondering whether Amazon had not turned down six-figure consulting offers from either of the authors to warrant this broadside.

- There is a laboured chapter on "engagement" - an attempt to define a compound measure based on essentially a summation of basically arbitrary weighted base measures. For instance, a measure of online engagement is a summation of eight different indices. Putting a "sigma" symbol in the equation makes it look impressive, but in the end it is more arbitrary than methodical. Because decision makers need to have information supplied to them in a simple manner, it is often supplied to them in a simplistic manner, cloaked in technical-sounding phrases.

- Privacy is becoming an increasingly sensitive and relevant issue as more data is collected from customers and users, often without their knowledge, and sometimes without their consent, almost always without providing users a clear picture of what is done with that user-data so collected. Privacy is an important topic in this discussion on enterprise analytics. And it is given short shrift in the book. After a cursory nod, almost as an afterthought, to privacy concerns, there are examples cited that are almost creepy in the extent they suggest the invasion of a user's privacy. Sample these: "The next generation of video game offers could have pictures of your friends or your tastes and interests built right in." Or "A company called Sense Networks has developed an application to help infer a person's lifestyle based on his or her location history." Harvesting a user's location and web-click information should require explicit opt-in - it is basic respect for human decency. Take the section where the authors talk about collecting data by anonymizing data. It has been proven that even after anonymizing data, it is possible to individually identify users with a very high degree of accuracy based on only a few attributes. There is no such thing as truly anonymous user-tracking on the web. Only if you use "unsophisticated marketing techniques" do you risk customer ire over harvesting their "spending habits", which they consider "inviolate". Get it? Be sophisticated, and you can get away with pillaging your customers' privacy. Is this really the new normal - customer privacy shmrivacy?

- Then there is this most curious statement that states - "Despite all the hype around the unstructured data component of "big data", it seems that structured data still rules the in predictive analytics." Well, yes! Unstructured data is fairly recent, especially when compared with structured data, that has been around for literally decades. It is but natural that the use of unstructured data in predictive analytics will take time to gain traction, especially as the technology and means of blending structured and unstructured data evolve.

- Even the chapter, "Predictive Analytics in the Cloud" contains phrases that make absolutely no sense, other than to bump up the chapter's jargon-index. Sample this: "These cloud-based solutions inject predictive analytics into other software that is cloud-based or delivered as SaaS." Is a specific example too much to ask? "inject" is an impressive-sounding word, especially if you have heard of the phrase "sql-injection" in the context of hacking attacks, but just what does the word "inject" mean in the context of predictive analytics and the cloud? And why does this injection require the cloud? Can it not be done with more traditional, hosted solutions? And what exactly are "cloud-based dashboards"??? Is any dashboard served via a browser "cloud-based"?

I could go on an on, but a short summary of the book would be this: each chapter suggests and promises value, but falls short.

In a good mood, as always.

TimesTen and Exalytics - Additional Features

Did you know that Oracle TimesTen In-Memory Database is available in four different licensing options, of which one is "Oracle TimesTen In-Memory Database for Exalytics"? Well, I think you knew that it is available with Oracle Exalytics, but were not sure that it is available in three other licensing options. In any case, what is interesting here is that the TimesTen In-Memory Database for Exalytics "license includes all features available under the Oracle TimesTen In-Memory Database license", but also has two additional features:
  • In-Memory Columnar Compression
  • OLAP Grouping Operators: Cube, Grouping Set, Rollup
From the short but useful paper, "Oracle TimesTen In-Memory Database Licensing Information", published December, 2012.

Read more about Oracle Exalytics In-Memory Machine, Oracle TimesTen In-Memory Database,

And, best wishes to all for a happy 2013.

Take care.
