The Oracle BI Mobile Demo Server

Yes. There is a live demo server now available for the Oracle Business Intelligence Mobile app. Specifically, this demo server supports the latest Oracle BI Mobile app, that went live some time back. That's good news, right?

How do you access it? The process couldn't be simpler. You need to do two things.
Access this page first.

You need to have an account on Oracle.com first. If you do not, you can register. It takes a minute, less I suppose if you're really fast at typing or are using one of those automatic profile plug-ins that store and regurgitate basic information like your name, address, contact details, etc... Anyway, I digress. If you have registered and have your account information handy, and I mean a login and password by that, please do go ahead and login. After you have logged in, you will be presented with this page, very simple, and all it does is ask for three pieces of information, and one item is optional, and one of the mandatory options is a radio button choice, so it's not asking for much, is it? Quite reasonable, and doable without fuss I would imagine.

After you have provided this information, the next page is even simpler. It provides you with a link to the Apple iTunes App Store to download the Oracle BI Mobile app from. This is the link, in case you are wondering. The second is a link to a PDF that contains the configuration instructions.

Once you have the configuration entered in the BI Mobile app, you are all set.

Happy analyzing.

Oracle Exalytics V1 Patch Set 1 is now GA

The Oracle Exalytics v1 Patch Set 1 is now generally available (GA). In fact, it has been available for a couple of weeks now. The update to Exalytics, the industry's first engineered in-memory analytics machine, delivers new capabilities, performance optimizations, Hyperion Planning, and Endeca Information Discovery.

This V1 Patch Set (v 1.0.0.1),  is recommended for all new and existing Exalytics customers.

So what's new in this update? Well, the software bits are new, as in updated. The three updated components of the Oracle Exalytics  v1 update are:
  • Oracle BI Enterprise Edition 11.1.1.6.2 BP1
  • Oracle TimesTen for Exalytics 11.2.2.3.0
  • Oracle Essbase 11.1.2.2.100
As you may be aware, the Oracle BI Enterprise Edition 11.1.1.6.2BP1 update provided several new capabilities across the board, the two biggest being enhancements in the area of visualizations and a revampled mobile app for the Apple iPad device. New Trellis visualizations - basically a grid of charts - that make it easy to visualize and understand massive data sets. When combined with the performance that Exalytics delivers, you get true speed-of-thought analysis. These Trellis visualizations support rendering data as new microcharts, like the SparkLine, SparkBar, and SparkArea microcharts. These are compact, cell-sized, data-dense visualizations and allow users to quickly discern the shapes and trends of data.

On the topic of in-memory analytics and performance, faster aggregate creation is now available, since both TimesTen and Oracle BI EE have been enhanced to enable faster data loads. Enhancements include parallel data load, index creation and disabling redo logging.

Separately, there there is a smaller footprint for TimesTen aggregates. The Oracle BI Server now generates a TimesTen optimized schema to significantly reduce the memory footprint used.

There is a Model Checker, faster query performance, and Faster aggregate recommendations.

With Oracle Enterprise Performance Management System Release 11.1.2.2, Oracle Hyperion Planning is supported on the Oracle Exalytics machine.

Oracle Endeca Information Discovery can now run on Exalytics with these versions:

  • Oracle Endeca Information Discovery 2.3.0
  • Oracle Endeca Server 7.3.2.

Then you also get Oracle Data Integrator certified to target TimesTen for Exalytics, and Oracle GoldenGate for TimesTen has been certified against TimesTen for Exalytics as a target.


And a bunch of other hardware related enhancements like Storage Area Network (SAN) Certification, and Auto Service Request (ASR) for Hard Drives.

Updated BI Mobile App Available (11.1.1.6.2.1140)

An update to the Oracle BI Mobile App became available a few days ago (iTunes link). You would have spotted this update on your Apple iPad devices, by the badge on the App Store icon, and this would also have appeared as in the list of updates available for your iPad device.




So what's new and what's different in this release?
Well, first of all, before you get into that topic, a note on how to identify this update.
When we released the Oracle BI Mobile App for the BI EE 11.1.1.6.2BP1 release, it had a version number of 11.1.1.6.2.1080

This new app has is versioned 11.1.1.6.2.1140
The second way to identify this as an update is by the date. On the Oracle BI Mobile app's page on iTunes, you will see a date of Aug 11, 2012. That is less than a week old.
Updated Oracle BI Mobile app, version 11.1.1.6.2.1140, in App Store App

So what's new in this app?

Basically there are a few bug fixes. These bugs were identified late in the release cycle, and in one case, I think, after the app had been on the App Store. The decision was to put out an update to the app a few weeks hence.
Some of the issues fixed are:


  • Slider prompt values are correctly being displayed and changed as values are updated.
  • Highly dense trellis charts no longer intermittently display network time out errors. If an actual network timeout occurs, end users will be provided with the opportunity to reload the data.
  • Presentation Variables with default values are now being correctly displayed
  • Sliders with ordinal numbers will appropriately populate the to and from fields.




The update process is quite straightforward. Once you tap to install the updated app, it downloads and installs in about a minute or less.


After the installation has completed, you can start the app and either log in to any of the connections you have - all connection information is preserved, or go offline and check the "Version" information to verify that you are indeed, running the latest and greatest (and updated) version of the Oracle BI Mobile App.

In closing, here are a few useful links:

Updated: to add a link to the tweet announcing the updated app, and this post. Very recursive, all this.

New Oracle BI Book Due Shortly

Mark Rittman, longtime Oracle expert, consultant, and now soon-to-be author, tweeted that the book he has been working on for some time, Oracle Business Intelligence 11g Developers Guide, should be "out soon", now that it has completed edits and final proofs. It promises to be an interesting read, and given its scope of coverage, I expect it to find its place on many an Oracle BI developer's desk.

It doesn't look like the book will be available in an ebook format like the Kindle, which is a pity. A 900 page book would be much more convenient to carry in bits-and-bytes I expect.

Oracle BI Mobile at the Speed of Thought

There is a new video available on the Oracle web site that showcases the new Oracle BI Mobile application for the 11.1.1.6.2BP1 release.

Here is the link: http://medianetwork.oracle.com/video/player/1730810620001

This is a short three-minute video that takes you on a fast-tour of the new Oracle Business Intelligence Mobile app for the Oracle BI EE 11.1.1.6.2BP1 release. I have been blogging about this release and this app for the past couple of weeks, and this video, produced jointly by our marketing and product management teams, put together a very neat and informative tour of the capabilities in the app and the release.






There is a link provided in the video for more information. And you can always get the app from the Apple iTunes App Store, the software bits from either the Oracle Software Delivery Cloud or from the Oracle Technology Network (Note: you will need to get the 11.1.1.6.2BP1 patch from Oracle Support)

And as I blogged yesterday (I am in Bangalore, ergo), you could try the new version of the Sample App to give the new release a spin, courtesy a Virtual Box Virtual Image, with all the software and data installed and pre-configured. Plug-and-play comes to enterprise software samples!

All posts on the 11.1.1.6.2BP1 release.

Oracle BI Mobile HD App - 2

Interactions
In my earlier post, Oracle BI Mobile HD App - 1, I started to talk about and show some of the capabilities of the recently released Oracle Business Intelligence Mobile app for the Apple iPad, as part of the Oracle BI EE 11g, version 11.1.1.6.2BP1 release. I blogged how you could download and install the app, and how the location intelligence feature works in it.

Continuing in that vein, I am going to take a closer look at some of the interactivity features available in this release.

Visualizations are an integral part of any analytics application. Visualizations are how data presentations best enable quick discovery of anomalies, trends, and areas for further investigation. Visualizations are what draw users to further explore data on a Dashboard. Yes, I know, I know. But the fact remains that a good visualization is well worth its wait in insight aurum. Tabular views have their own place in the scheme of things, but visualizations grounded in sound theory are what provide the quickest bang for the buck. In short, I seem to be saying visualizations, and good visualizations specifically, are the answer to global hunger. No, I am not, but within the context of data analysis I would venture and say a good visualization is worth a thousand insights.

Oracle BI EE offers a rich palette of visualizations from which to construct Analyses and Dashboards. For facilitating detailed inspection of data you have the table view. For a multi-dimensional yet detailed look at data, there is the Pivot View. Charts offer the convenience of being able to provide high-level overview of data, with the option of drilling down for viewing trends and data at a more granular level, while tooltips offer the convenience of providing specific, accurate values of data, while at the same time not adding unneeded artifacts to the visualization (a double-negative is a no-no in writing, but I don't lay any claims to literary aspirations).

Coming to the specific topic of visualizations like graphs, and how to interact with them on tablets like the iPad, let's take a look at two topics. The first is "tooltips" and the second is interactions. Actually, both are interactions, but you will see what I mean in just a bit.

As I mentioned earlier, charts are very useful because they provide a great way to take-in all the data being displayed in one glance, without being overwhelmed with the details. Put another way, you want to make use of your pre-attentive processing skills here. Look at a chart and without consciously making an effort, get a general "sense" of the data displayed. After that, you can start exploring. Exploration usually begins with a simple gesture, a simple action like invoking a tooltip. On the traditional desktop browser this easy enough to do - you move your mouse over the concerned series, and a tooltip pops-up with the relevant information. Secondly, when using a mouse, you have much greater control over the preciseness of movement and therefore, even with small charts where data is densely packed, you do not experience usability issues.

Not so much the case with touch devices. On touch devices, you do not get a tooltip via a hover gesture. In fact, several design guides for touch computing proscribe using hover gestures, which makes sense. At least for now, no hover gesture is workable on tablets - you cannot really place your finger a teeny weeny millimeter over the tablet and expect a hover tooltip to materialize. At least, not yet. On the other hand, people using traditional computer interfaces that support a mouse have become very used to hover gestures providing context and additional information - the hover tooltip is a great aid in discoverability. Some may argue that a hover gesture should not be required, and when relied upon is often an indication of a poor design. There may well be a smidgeon of truth in that, but the fact remains that the hover gesture can greatly reduce unintended clicks.

On touch devices, you have to tap to get a tooltip, or invoke whatever action has been defined on the item being tapped. The second issue is that preciseness of touch does not match that of a mouse on a computer. Doesn't even come close. So when you tap on an item, it is not guaranteed that you will in fact end up tapping that intended item. Apple says as much, which is why their design guidelines call for a minimum dimension for buttons and tap targets. However, when you are dealing with dynamic views like charts, where you could get as few as four values at one level of a hierarchy, and drilling down could result in tens, even hundreds of values, this can be a problem. For instance, at the region level, my chart may show only six countries for South Asia - India, Pakistan, Bangladesh, Nepal, Sri Lanka, and Bhutan. Drill down India, and I could end up with over 600 items, if my next level in the hierarchy is showing data at the "district" level. A problem. On the browser interface of Oracle BI EE, this is not really a problem, because the "zoom-and-scroll" feature on graphs is intended to address precisely this issue.

So how does the Oracle BI Mobile app handle this problem? By supporting touch gestures.




That's it? No more details?
Yes, yes, details, details, details.
What are the most popular and useful charts? The bar? Yes. Vertical bar chart? Yes. Stacked Vertical Bar? Yes. Horizontal Bar? Yes. Stacked Horizontal Bar? Yes. Line? Yes. Basically, let's take a look at what I consider the most popular and perhaps even the most useful of charts, the bar chart. The good old bar chart. The much abused bar chart.

Consider the screenshot below, and notice the stacked vertical bar chart displayed in the bottom left corner of the screen. Here I am plotting "Revenue" data at the grain of "Month" and "Brand". This means, that my series is by "Month", i.e. the X-axis is plotting data by month. My grouping of data is by "Brand", i.e. within each month, I have grouped my data by "brand". Each stacked bar for each month represents Revenue data in a given month for a given brand.

If I need to interact with this data, I need to be able to tap on any bar and get a tooltip. The tooltip would then provide me with information about the item tapped, but also let me initiate an action on the item. The action could be "nothing" - as in the report author did not provide any interaction that could be performed on the item, "drill" - as in drill down the item tapped, "actions" - as in invoke the Action defined on the item or display a menu of Actions available for the item, and "send master-detail event" - as in send a master-detail event on the channel specified in the analysis.

To get a tooltip, tap on the bar. A color-coded tooltip is displayed. What this means is that the leader line of the tooltip as well as the border color of the tooltip is the same color as the bar you tapped. Helps, doesn't it.


But what if you did not intend to tap on the bar for the "HomeView" brand? That's ok, because you can drag the tooltip. Drag, did I say? Yes, Tap anywhere in the tooltip, except on the button, and drag the tooltip down, or up. If you drag it down, the tooltip will snap to the next item in the series, and update to display you data for the "FunProd" brand. And you can see that the color of the leader and the border of the tooltip changes. Drag up, drag down.


Repeat it and drag the tooltip all the way down, to the first brand, "BizTech"

So this is how you can tap and drag the tooltip within a series. But what if you want to drag it across a series. I.e. you want to see data for a selected brand across all the months that you have displayed on the chart? Yes, of course, be my guest. Tap and you get a tooltip. Now tap-and-drag this tooltip across the chart, and the tooltip merrily accompanies your drag gesture, the information inside the tooltip changing as you move from one bar to the other.
Now, these tooltip gestures are not limited to standalone charts. These are also available in the Trellis view. The new kid on the visualizations block in this release. Specifically, the tap-and-drag gesture is available in the Simple Trellis. What is a Simple Trellis? It is a Trellis visualization that supports one visualization across the entire Trellis. And we will talk about that in a future post. As the next two screenshots illustrate, you can tap inside a cell in the Trellis grid to get a tooltip, and then drag this tooltip within the cell.





What about the Advanced Trellis and tooltips and gestures? First, what is an Advanced Trellis? An Advanced Trellis is a Trellis view that supports multiple visualizations; i.e. a different visualization per measure. And we will talk about this in a later post. An Advanced Trellis also makes use of microcharts, like the SparkBar, SparkLine, SparkArea - which means that they are even more suited to visualizing large amounts of data - literally thousands of data points in a Single Trellis view, hundreds in each cell. In spark visualizations, the intent is to discern the overall trend and shape of the data in a cell, and not so much on the individual values. Therefore, what is most appropriate for a cell in an Advanced Trellis is to provide a summary of the data - the measure name, the initial or starting value, the last or end value, and the minimum and maximum values.





I really want to get this post, err... posted, so I am excluding other interactions on graph views that I wanted to talk about from this post, and will include them in a subsequent post.

Thank you.
