The ratings and analytics service wanted a more agile approach to its database, so it adopted NoSQL technology to improve performance and boost the bottom line.Today, businesses increasingly live and die by analytics. For, which manages massive volumes of data and delivers highly targeted results for clients, the ability to sift through datasets quickly and effectively is critical.' There are tremendous challenges associated with putting all the data to maximum use,' says Arvind Jade, architecture lead at Nielsen.The company, which delivers ratings data and other information for businesses in more than 100 countries, faced growing challenges associated with its Global Buy Platform and Answers on Demand (AOD) services. Nielsen provides powerful analytics and reporting capabilities—essentially aggregations on the fly—through an on-demand big data platform. It serves some of world's largest retailers and others, who track sales of fast-moving consumer goods to drive pricing, product placement, marketing efforts and customer loyalty. 'We essentially function as a document store,' Jade says. Unfortunately, the system was slow at times, particularly when the metadata underwent changes.
'We needed to adopt a more agile approach and achieve gains in efficiency,' he adds.The company turned to Couchbase, which delivers a NoSQL technology approach that sidesteps many of the limitations of relational databases operating in a multitenant environment. The system delivers about a 50 percent boost in response time by pre-indexing metadata.' By moving the metadata to Couchbase, we were able to dramatically improve the efficiency of the system and speed data delivery,' Jade says. 'We are able to query against the index and target specific documents, something we were not able to do previously.' In addition, the ratings firm gained more detailed and granular internal reporting tools, including an ability to dive deeper into user patterns and behavior. That has translated into Nielsen designing better products and adapting systems to better fit changing customer buying patterns and behavior.' We are able to react in a more agile and flexible way,' Jade explains.
Moreover, the NoSQL approach has reduced the time required to manage and update systems. 'We can use IT staff to add greater value to the business,' he says.The transition to the system proved relatively seamless. Jade says that the company began using the technology about five years ago, but underwent a major upgrade about a year-and-a-half ago.The initial transition took about six months, though installing the Couchbase component took less than a month, and the metadata change management process required less than eight hours. Nielsen was able to tap in-house developers and staff with existing Java skill sets to handle the coding and develop the necessary APIs.Nielsen is now exploring the use of Couchbase Lite, which would introduce a mobile component. Although the current environment is mobile-friendly, it does not yet offer dedicated support for iPads and other tablets and smartphones.'
We are able to put data to work in a more efficient way,' Jade says, 'and we have built a strong foundation for the future.'

UML Spreads Its Wings. By Deborah Melewski. The Unified Modeling Language (UML), created with great fanfare by three of the world's top methodologists, was adopted as an Object Management Group standard in 1997. By that time, UML had gained the support of virtually all development tool makers, ranging from its creator, Rational Software Corp., to industry leaders like IBM and Microsoft Corp., as well as a slew of smaller suppliers.The next step was to convince corporate development managers and their teams that the time had come to bring order to development projects that were becoming more complex as the World Wide Web was added to the mix. In many cases, development managers have seen the light. This story looks at how corporate development groups at ACNielsen, Kesmai Studios and Loewe GmbH have turned to the UML for strategic new projects.At marketing research company ACNielsen, Schaumburg, Ill., all new software development projects begin with UML and the Rational Rose object modeling and design tool from Rational Software Corp., Cupertino, Calif. In fact, ACNielsen Senior System Architect Joe Canon will not even OK the start of a project until the use cases have begun for its requirements portion.
'Object modeling helps us design better systems, while also making them less error-prone and much more maintainable,' said Canon. 'The quality and stability of our software is of the utmost importance, and a problem with the software is unacceptable,' he explained. 'When you develop syndicated software and you ship 30,000 CDs, you don't want to be saying 'oops' afterwards.' ACNielsen, with 1999 revenue of $1.5 billion, develops syndicated, in-house and custom applications software for measurement and analysis of marketplace dynamics and consumer behavior. Clients include leading consumer product manufacturers, retailers and service firms, media and entertainment companies, and the Internet community. The company's syndicated OLAP tools have migrated through the years all the way from mainframe processes to DOS, to Windows to 32-bit componentware.Now in its fourth year, the UML has documented success stories in both large and small development projects. While the UML has been criticized by some in the industry for its complexities and size, these are non-issues at ACNielsen.
More than 100 developers are working on various U.S. Projects within the company, and many of the UML's components have served a significant purpose within the company.Figure 1 goes here.This screen capture from ACNielsen shows how the company did its design using the Unified Modeling Language (UML) and Rational Software's Rational Rose product.At ACNielsen, the UML's use cases provide a means of identifying and clarifying requirements in the functional areas. Use cases have also been beneficial in serving as a common language between the company's business analysts, development teams, designers, domain experts and marketing personnel. As the team goes further into identifying how repetitive certain operations might be, and how often things may be used, use cases have also helped to determine what some system requirements might be. 'How a system is used is sometimes the best way to identify your technical needs,' said Canon.Following the use cases, the team moves through the Analysis Model to do a logical analysis of what needs to be done to fulfill the use case functionality.
'The Rational Rose tool helps us a lot there because it's easy to use with its drag-and-drop capabilities,' Canon said. 'The tool also has a simple F5 command to create your collaboration diagram, which saves a lot of time.' From there, the team takes the sequence diagrams that were completed in the analysis phase and uses them as the framework for the detailed design sequence diagrams. 'Doing the collaboration diagrams along with the sequence diagrams also helps in mapping to the use cases,' said Canon.' Collaborations are good because things become time-independent. Giving you a straight feel for the different object interactions,' he added. 'This helps you with normalizing and de-normalizing your object models, and in figuring out which ones should be independent classes and which ones are actually the same objects.'
Sequence diagrams define the ACNielsen team's classes, associations, generalizations and stereotypes. Canon also likes the way Rational Rose works with the UML to let him define his own stereotypes. 'We fully round-trip engineer,' he said. 'Once we have a pretty good first cut of our classes and definitions, we go through the component tool and assign different classes to the different languages necessary, be it C, Visual Basic or Java.' On the Java front, the company recently started a new project by reverse engineering an existing Java application.
During that process the Rational modeling tool was used to identify inefficiencies as well as to polish class interfaces.' One of the stronger aspects of the UML and modeling is that you can visualize your system,' said Canon. 'Sometimes when you're looking at piles and piles of code you can lose sight of the overall picture and interactions,' he added. 'Just going through the code you don't always know how every object is used, so you can very easily fall into the mistake of changing a method or property, or an operation attribute, thereby affecting many things and not knowing about it right away. By doing all of your object manipulations through the models, you have a better chance of catching any mistakes up front.'
ACNielsen uses the UML all the way down through the Software Quality Assurance (SQA) process. The company's SQA team creates test scenarios from a project's use cases. 'When they find an issue in the system, we can track it down through the design module to see how the use case started; we can check Sequence Diagrams to see how the system is supposed to be flowing, right down to the classes that are implemented. We can debug our software much more quickly because of that connection,' said Canon.The UML has proven beneficial in many projects during the last few years at ACNielsen, with leading OLAP products such as Nitro and NetDispatch backed by UML and object modeling. Even the company's custom applications team has moved to the UML. 'As people get over the stigma that object modeling slows you down, and that if you're in a fast-paced RAD development mode it doesn't lend itself to object modeling, they're finding that this isn't the case,' noted Canon.' You can move at a fairly good pace as long as you can keep people focused on the fact that it is an incremental and iterative approach all the way from the beginning, not just in the coding,' he added.
'The number one thing I watch out for is that we don't fall into an analysis paralysis mode. This is a major pitfall when people think they have to have the full system spec'd out to the most minute detail in their use cases before moving to the next phase,' he concluded.Designed from the ground upAnother successful UML implementation comes from Kesmai Studios, the Charlottesville, W.

Va., unit of interactive entertainment company Electronic Arts, which posted $1.2 billion in 1999 revenue.A pioneer in the online game industry, Kesmai Studios' earliest offerings were text-based, role-playing games. In 1987, Kesmai launched the world's first graphic multi-player online combat game, the Air Warrior flight simulator.During the last two years, Kesmai Studios has been moving from C to C as its programming development language. 'In that time, we've also seen the benefit of using object-oriented analysis and design in conjunction with C to get the most out of our project,' said Tim Price, software engineer. 'We then started looking at methodologies that would provide as good a design as possible before we started coding.'
The code for the current flight simulator had been around for 15 years, with multiple patches showing its age. 'We decided it was time to start over, from the ground up, with a real design from the beginning and no assumption that we could use any of the old stuff,' said Price.
