Most organizations don’t really have single centralized Active directory forest. The multiple directories and forests are present from different reasons incorporate corporate security recommendations or acquisitions and mergers. Due to this, the organization could face a challenge for data technology groups that must deploy applications and details to users that exist in separate directories. A virtual directory can help in solving this by offering joined view of data from numerous directories with no forest trusts.

Employing a virtual directory will help organizations aid in reducing IT fees because it makes it possible for one to deploy applications in a faster pace across numerous existing LDAP directories. This also assists the organization get rid of minimize password synchronization across LDAP directories. Lastly, a virtual directory server can help in the reduction of complexity in identity management deployment by enable data access directly from the source.

Yet another advantage of employing a virtual directory is it can aid in meeting audit and compliance initiatives. It comes with comprehensive and total audit logging of each activity. All operations of LDAP are stored and simultaneously logged for the database for a far more convenient retrieval and reporting. This enables you to report on if a person logged in and when such as the alterations which have been made. Apart from that, the reports may also be auto scheduled for the objective of e-mail distribution in various kinds of formats.

Lastly, the use of virtual directory is important because it helps in increasing the security of one’s environment. It isn’t only a directory; it is an LDAP proxy as well. With this, you might be able to gain control more than the accounts that happen to be connected and search your directory. This also creates a limit from the entry points within the Active Directory and may additional defend it. It can also monitor and report the modifications in real time and can limit the modifications performed against the LDAP directory.

Moskowitz is mostly reiterating what he heard from Apple CEO Tim Cook and CFO Peter Oppeheimer in a recent sit-down with them, during which they discussed the Kindle Fire’s role in relation to the iPad. Moskowitz came away with the clear impression that “Apple is not seeing much pressure from lower-priced tablets,” and that current Kindle Fire buyers “could gravitate to more feature-rich experiences” down the road based on their initial use of the cheaper Amazon device.

J.P. Morgan and Apple execs apparently aren’t all that concerned over Amazon’s new Android tablet, which is already projected to beat out the sales of all other tablets based on the Google mobile platform by the end of this quarter. And it’s true that the Kindle Fire could act as a sort of gateway drug, turning users on to the tablet experience but leaving them craving features missing from the Amazon device, like a full-fledged market of applications targeted to large-screen devices, a larger screen itself and cellular data access.

It’s an admittedly rosy outlook from a source with a vested interest in seeing this outcome come to pass, however. There’s another obvious possibility to contend with too: Users could find that the Kindle Fire provides everything they really need in a tablet experience (web browsing, media playback) for an acceptable price and look no further. Whether or not those users would’ve looked at iPads otherwise, or whether another, significant portion of Fire owners might not find themselves wanting more is another question.

I think Apple’s optimistic outlook should pan out, however, so long as one thing remains true: tablets continue to encroach upon and replace PCs as primary computing devices for general users. In that case, the Kindle Fire and the iPad likely will indeed enter into a mutually beneficial orbit, with the cheaper device drawing in first-time tablet users and the iPad acting as a sort of graduation gift for when they opt to use tablets as their main computers.

Thomas Chippas, managing director at Barclays Capital, notes that there is no standard definition of what risk means in the financial services industry. For a true picture, you have to query data in real-time across institutions, including terabytes of your own data as well as data extended into other databases to assess the full risk. Back in October 2008, a federated group of datastores existed, the risks might have been more apparent. That type of federated data access still doesn’t exist today. What needs to come next is a way to put that data together in a useful way.

The complexity of the necessary analytics task is daunting, because there are multiple correct answers, and no uniform standard for structuring data. There are at least 40 different schemes considered appropriate when it comes to how trading information is provided.

Zane said that what’s been driving the development of new technology has been a combination of economics, regulation, and businesses looking to get ahead. The industry is now at the point of same-day need for analysis. More data, but the timeline is shrinking. Companies want to get to same-minute, as close as possible after trading, activity — requiring massively parallel computing.

Currently, the financial industry has a great deal of historical data, but with social media comes the addition of instant news, telling traders how to shift things around to be profitable — or even survive.

Most risk analysis involves continuously running models to assess risk, as well as ad hoc querying where you can’t predict its nature, like the events in Japan: an actual event that goes beyond the models built to assess possible risks.

Minder Cheng, board member of Investment Technology Group, notes that in the wake of the events of 2008, TARP had to be introduced because no one was going to support another 0 billion bailout. If there had been a chance to somehow look at the exposure across all the banks and see what could happen with the market, alarms might have gone off alerting them that billions were at risk.

This type of analysis can be both offensive and defensive, but risk management is never about being on the defense; it’s about letting CEOs make decisions regarding risk-adjusted returns. Every investment decision is made by evaluating risk vs. return trade-off. Risk management is both a data exercise and analytics exercise.

Every simulation should be saved so all possible situations can be bumped up to assess the biggest risks. If you save everything from one day’s simulations, double-digit terabytes of data are saved merely during the course of one day.

Chippas noted all these terabytes are generated before the trading even takes place. With today’s technology, businesses have to make a choice between speed and risk analysis. Everyone has to recognize the limitations and associated constraints that result.

Zane said that where companies formerly handled thing in-house, as the volumes grow and analytics more severe on more data, the transition isn’t so much away from traditional structures as away from proprietary solutions. The shift allows more ad hoc analytics and more agility, as the analysis is no longer done by hiring programmers, but by using standardized languages and APIs.

Cheng stated that technology is being driven both by regulators (they don’t want to bail out again) as well as banks wanting to maximize risk-adjusted returns.

Chippas added that there isn’t a day that goes by that they aren’t trying to optimize: processes, technology, etc. It’s an ongoing trajectory of trying to provide a broader base of analytics, without more infrastructure if possible, stating, “It never ends. If we can do it faster, cheaper, broader, better than anyone else, that’s the goal.”

Smith closed by asking the panelists if they would use any of these applications on the cloud? Cheng answered quickly with an unequivocal “No”  due to the sensitive nature of the data, as well as local laws. China, for instance, wouldn’t allow companies to store data in the cloud; regulations require all data stay in house.

Chippas closed by adding, “You don’t want to be the guy who had the data in the cloud and lost control of it.”

It’s the great flexibility of XML that makes it so appealing to web developers. Due the structure of the markup language, data exchange is possible in many different forms. Additionally, users find that XML makes data access simpler than is possible with HyperText Markup Language, more commonly known as HTML. Consider that XML programming has the capability to display one web page in either a mobile or regular format, depending on the user. In other words, programmers don’t need to make a “mobile” and “regular” site if they don’t want to. The ease and efficiency of XML should be becoming more clear.

It isn’t necessary to have extensive prior experience with HTML in order to operate well using XML. The two do go hand-in-hand in many respects, since they are both descendents of SGML, another markup language. The purpose of a markup language is to organize, categorize, or otherwise label content, and the markup describes the organization. Markup contains content, which is what you see when you look at an XML document.

The need for XML emerged when the limitations of HTML became clear. In HTML, users cannot add new markup elements. With a need for greater flexibility, XML evolved to meet the needs of document and data handling in a web environment.

This is just a short introduction for those who wonder just what the heck XML is. If you’re an aspiring web developer, XML learning should definitely be on your “to do” list.

We’re only about five weeks away from Christmas, so now’s as good a time as any to talk about (drum roll, please) e-books. Amazon kick-started the e-book market (with apologies to earlier e-book readers) with the introduction of the Kindle in the fall of 2007. Two years later, Barnes and Noble, IREX, and Sony announced new or updated e-book readers of their own.

The question becomes, which e-book reader is right for you? The truth is, they’re all very similar, so it should come down to what books their compatible book stores carry. Oh, and price, of course.

Amazon Kindle

Amazon Kindle: Starting at $259 (Amazon.com)

The elder statesman of the current crop of e-book readers, the Amazon Kindle is now in its second iteration (putting aside for a moment the Kindle DX, which isn’t exactly a “traditional” e-book reader, if such a thing even exists). As the name suggests, it has the full backing of Amazon—you may have heard of it—which should ensure that it’ll stick around for a while. You can find it on Amazon.

Features:

• Compatible with e-books (and magazines and newspaper) purchased from Amazon. There’s some 360,000 books available, so odds are you’ll find something you like.

• 6-inch, non-touchscreen E Ink display. Very legible, believe me.

• Free 3G wireless data access. That means you don’t have to be tethered to a computer to add new books to your device.

• It now works in more than 100 countries, including the UK, France, Germany, Spain, Japan, Australia, and Brazil.

• Holds up to 1,500 books simultaneously.

Barnes & Noble nook

Barnes & Noble nook: $259 (BarnesandNoble.com)

Yes, the nook is written in all lowercase letters, so accept no substitutes. It, along with the Kindle, is destined to become one of the two biggest e-book readers available. It’s backed by the enormity of Barnes & Noble, and all that that entails, has a color scroll bar at the bottom (color = huge when it comes to e-books), and seems to do just about everything right… It’ll be available in a few days (currently scheduled for a November 30 release) from the Barnes & Noble Web site and brick-and-mortar stores.

• 6-inch E Ink display, with color touchscreen navigation bar along the bottom. Note that the screen itself isn’t in color, just that navigation bar.

• Free 3G and Wi-Fi.

• Works with the Barnes & Noble e-book store, which has “thousands” of books.

• Enough storage space to hold around 1,500 books, plus a microSD card slot in case you need more space.

Sony Reader Daily Edition

Sony Reader Daily Edition: $399.99 (SonyStyle.com)

Sony has been in the e-book business for a while now, but the Daily, as it’s called when brevity is an issue, is the company’s latest attempt to make these things finally “click.” As of this writing (November 19, 2009) it’s not actually available yet, but Sony says it will ship in time for Christmas. (It’s available for pre-order right now.) The following is based on what Sony has already publicly announced.

• Compatible with more than 40,000 books from places like the New York Public Library and overdrive.com. (Interestingly, not all of Sony’s partners have been revealed yet.)

• 7-inch, touchscreen E Ink display.

• Free 3G wireless data access. Again, no having to be tethered to a computer to download new content.

• Supports a whole host of file formats, including Adobe PDFs (hello, alt.binaries.books!), Microsoft Word documents, and MP3/AAC audio.

• Thanks to the touchscreen, you can take notes on it like you would a regular notebook. Might be handy.

IREX DR800SG

IREX DR800SG: $399.99 (IREXReader.com)

This little guy was the first e-book reader announced to include support for the Barnes & Noble e-book store. It has the biggest screen of the lot, and manages to check all the right boxes. Its name is woeful. Like the Sony Daily, it’s not available yet, but will be at Best Buy and online in a few weeks.

• 8.1-inch, touchscreen E-Ink display (but it uses a stylus, so…)

• Compatible with the Barnes & Noble e-book store, along with Newspaper Direct and LibreDigital.

• Free 3G wireless, plus Wi-Fi.

• Unique navigation via left-hand side bar.

• If you want to support the future, IREX has already said that it’s working on a full-color e-book reader that it intends to launch next year. It’s the only manufacturer to commit to releasing a color reader just yet.

Faster data access with virtually no latency: LTE (Long Term Evolution) mobile broadband networks are coming, at least in the world’s most advanced mobile market, the nation of Japan. The country’s biggest cell phone carrier, NTT Docomo, said yesterday at GSMA Mobile Asia Congress in Hong Kong it will go fourth generation as early as December 2010.

Correct me if I’m wrong, but wasn’t the Amazon Kindle the first device to launch with built-in wireless (that is, cellular data) access? You know, you pay for the device, and then you don’t have to pay monthly wireless access because it’s already included in the cost of the device? It’s pretty neat, I think I can say without too much grief, and is a model that’s been copied by other e-book readers. Now it looks like Nintendo is considering such a model for future versions of the Nintendo DS (and not necessarily the XL, mind you). Exciting!

So Nintendo’s president, Satoru Iwata, said at a recent briefing that he’s “interested” in the business model (wireless access that’s built into the cost of the device) because it’s new, and, well, it could help expand the popularity of DSi Ware. Right now, to access DSi Ware you need to be connected to Wi-Fi, which sorta limits its availability. What if you’re sitting on a park bench on a warm spring day and want to download Something? You can’t!

You can imagine other scenarios, I’m sure.

Iwata did express concern that Nintendo would have to be careful with such a model because Nintendo is, in his words, an “amusement company.” It’s not Apple in the sense that it can’t charge $LOTS for its products.

Such a move would also give this theoretical new DS an edge over the PSP Go, which you’ll recall only ships with 802.11b access. That’s a bad move on Sony’s part, yes.

Keep in mind that Iwata could have just been thinking out loud, and that none of this will ever see the light of day. So there’s that.
