I forget: what's in-memory?

Boris Evelson

By Boris Evelson
 

In-memory analytics are all abuzz for multiple reasons. Speed of querying, reporting and analysis is just one. Flexibility, agility, rapid prototyping is another. While there are many more reasons, not all in-memory approaches are created equal. Let’s look at the 5 options buyers have today:
 

1. In-memory OLAP. Classic MOLAP cube loaded entirely in memory

Vendors: IBM Cognos TM1, Actuate BIRT
Pros

  • Fast reporting, querying and analysts since the entire model and data are all in memory.
  • Ability to write back.
  • Accessible by 3rd party MDX tools (IBM Cognos TM1 specifically)

Cons

  • Requires traditional multidimensional data modeling.
  • Limited to single physical memory space (theoretical limit of 3Tb, but we haven’t seen production implementations of more than 300Gb – this applies to the other in-memory solutions as well)

 

2. In-memory ROLAP. ROLAP metadata loaded entirely in memory.

Vendors: MicroStrategy
Pros

  • Speeds up reporting, querying and analysis since metadata is all in memory.
  • Not limited by physical memory

Cons

  • Only metadata, not entire data model is in memory, although MicroStrategy can build complete cubes from the subset of data held entirely in memory
  • Requires traditional multidimensional data modeling.

 

3. In memory inverted index. Index (with data) loaded into memory

Vendors: SAP BusinessObjects (BI Accelerator), Endeca

Pros

  • Fast reporting, querying and analysts since the entire index is in memory
  • Less modelling required than an OLAP based solution

Asset Virtualization – When Avatars Are Field Engineers

Holger Kisker

Smoke and fire is all around you, the sound of the alarm makes you dizzy and people are running in panic to escape the inferno while you have to find your way to safety. This is not a scene in the latest video game but actually training for e.g. field engineers in an exact virtual copy of a real world environment such as oil platforms or manufacturing plants.

In a recent discussion with VRcontext, a company based in Brussels and specialized since 10 years in asset virtualization, I was fascinated by the possibilities to create virtual copies of real world large, extremely complex assets simply from scanning existing CAD plans or on-site laser scans. It’s not just the 3D virtualization but the integration of the virtual world with Enterprise Asset Management (EAM), ERP, LIMS, P&ID and other systems that allows users to track, identify and locate every single piece of equipment in the real and virtual world.

These solutions are used today for safety training simulations as well as to increase operational efficiency e.g. in asset maintenance processes. There are still areas for further improvements, like the integration of RFID tags or sensor readings. However, as the technology further matures I can see future use cases all over the place – from the virtualization of any kind of location that is difficult or dangerous to enter to simple office buildings for a ‘company campus tour’ or a ‘virtual meeting’. And it doesn’t require super-computing power – it all runs on low-spec, ‘standard’ PCs and the models are only taking few GBytes storage.

So if you are bored of running around in Second Life or World Of Warcraft, if you ever have the chance, exchange your virtual sword for a wrench and visit the ‘real’ virtual world of a fascinating oil rig or refinery.

Please leave a comment or contact me directly.

Kind regards,

Liberty, equality and mobility

Thomas Husson

I find it quite amazing to see the societal impact of mobile phones. 

They have changed the way we communicate and live. There is a drastic change in the way children and parents communicate, in our individual relationships with time and location and in so many other parts of our daily lives. There are interesting books and theses about this topic. I recently came across an interesting view point from Russell Buckley about the "Unintended Consequences and the Success of Blackberry in the Middle East", which is further proof of how disruptive mobile can be. As communication and creation/media tools, mobile phones offer new ways to upload and access information (remember the riots in Iran). As such, governments have to monitor and anticipate this impact. 

Beyond this, public authorities can make the most of mobile services. Many local councils, regional and national governments, and transport authorities are launching mobile initiatives, creating new value-added services for citizens, and trying to use mobile to connect with the least connected. They need to anticipate the arrival of NFC technology and make the most of more mature mobile ecosystems. They should balance their mobile investments with the constant need to avoid discriminating against particular groups of citizens and to allocate funds to projects with critical mass. Governments in particular can play a key role in stimulating ideas for new services and in backing and funding the most relevant initiatives.

The Online Panel Quality Debate

Reineke Reitsma

A few years ago, Procter & Gamble publicly stated that it had experienced inconsistent research results from successive online research projects. Other organizations shared similar experiences, and questions were raised about “professional respondents.” The trustworthiness of online research was in question, and multiple initiatives arose. In the past two years, we’ve seen a lot of debate around this topic, and associations such as ESOMAR and ARF have come up with protocols that all good panels should follow — and many have. But what does this mean from a client perspective? How have initiatives like ARF's Quality Enhancement Process, MarketTools' TrueSample, or processes like machine fingerprinting changed the industry?

Next month, I'm hosting a panel at Forrester's Marketing Forum 2010 with participants from Microsoft, Procter & Gamble, and the ARS Group to understand what the challenges with online sampling are today — and how they affect adaptability.

Questions I will discuss with the panel include the following:

Brain Fitness Joins Physical Fitness As Part Of A Workout Strategy

Claire Schooley

I had an interesting discussion today with a new company called Cogniciti that is developing a platform for helping adults “extend their memory and cognitive abilities longer in the lifespan.” Based on research from Baycrest, a health services center focusing on aging and affiliated with the University of Toronto, the company’s work is grounded in solid research.

I think extending one’s memory to stay as sharp as possible in both professional and personal life is a hot topic that is growing fast as an essential component of general fitness. We spend hours at the gym maintaining our physical fitness. But in order to enjoy our healthy bodies, we also need to be mentally fit.  In the last few months, I’ve seen a lot of emphasis on informing people about what they can do to maintain their memory. PBS had a special over the Holidays and a brain fitness package was one of the “thank you” gifts for pledging money to the TV station. I picked up an AARP magazine in a doctor’s office last week and the lead article was on exercising the brain through challenging games. I felt quite satisfied when I completed the puzzles effortlessly (whew!)

I’m convinced we will see brain fitness as a soft skill for employees in the corporate world. Everyone can use memory strategies to improve their work performance. I like the blend of research and technology. Using self-paced online information and exercises that use simulations and other multimedia production techniques combined with self-study and online discussions give employees a complete brain enhancing program. Employees can also access brain games and exercises from their mobile device and get some brain stimulation on the way to work in the morning!

The Battle Of Partner Eco-Systems

Holger Kisker

On the need to analyze, compare and rate partner eco-systems – please vote.

The world is becoming more and more complex and so are the business challenges and their related IT solutions. Today no single vendor can provide complete end-to-end solutions from physical assets to business process optimization. Some large vendors like IBM, Oracle or HP, have extended their solution footprint to cover more and more of the four IT core markets hardware, middleware software, business applications and services but still require complementary partner solutions to cover end-to-end processes. Two examples of emerging complex IT solutions include:

  • Smart Computing integrates the physical world with business process optimization via four steps: Awareness (sensors, tags etc.), Analysis (analytic solutions), Alternatives (business applications with decision support) and Action (feedback loop into the physical world). A few specialized vendors such as Savi Technology can cover the whole portfolio from sensors to business applications for selected scenarios. However, in general a complete solution requires many partners working closely together to enable an end-to-end process.
  • Cloud Computing includes different IT resources (typically infrastructure, middleware and applications) which are offered in pay-by-use, self-service models via the internet. The seamless consumption of these resources for the end user anytime and anywhere however requires multiple technologies, processes and a challenging governance model often with many different stakeholder involved, behind the scene.

Three Top Questions To Ask a BI Vendor

Boris Evelson

By Boris Evelson

 

An editor from a leading IT magazine asked me this question just now, so I thought I'd also blog about it. Here it goes:

 

Q1: What are the capabilities of your services organization to help clients not just with implementing your BI tool, but with their overall BI strategy.

 

The reason I ask this as a top question, is that most BI vendors these days have modern, scalable, function rich, robust BI tools. So a real challenge today is not with the tools, but with governance, integration, support, organizational structures, processes, etc – something that only experienced consultants can help with.
 
Q2:  Do you provide all components necessary for an end to end BI environment (data integration, data cleansing, data warehousing, performance management, portals, etc in addition to reports, queries, OLAP and dashboards)?
 
If a vendor does not you'll have to integrate these components from multiple vendors.

Integrating Social Media Into B2B Marketing Strategies: A (Final) Webinar With Harte-Hanks

Laura Ramos

Four years ago, I waved good-bye to my Pharma industry research and began writing about B2B marketing best practices, as part of Forrester's marketing and strategy research group headed up by Elana Anderson. Harte-Hanks sponsored my first Webinar in this new role -- called "Improving the Maturity of your Lead Management Process" -- and Elana and I teamed up to present the webcast that aired on June 7, 2006. At that time, my research on lead management best practices was only beginning and social media was an emerging concept that Charlene Li had just started to explore in Forrester's seminal research, the "Social Computing" report. A lot has changed since then.

Through an amazing coincidence, my life as one of Forrester's top B2B marketing analysts begins and ends with Harte-Hanks. Tomorrow, March 30, I will broadcast my last Webinar with Forrester and I am so very pleased to do so with folks at Harte-Hanks who helped me launch this journey.

Windows 7 Early Adopters Were Satisfied Upgraders

JP Gownder

We've just published two new reports concerning Windows 7 adoption and satisfaction, leveraging Forrester's Consumer Technographics(R) data. 

The reports show that Windows 7 penetrated the consciousness of the market by the end of 2009, with a strong majority of US consumers aware of the product.  We also found that consumers who adopted Windows 7 in Q4 were generally very satisfied with their Windows 7 PCs. 

Perhaps the most interesting finding of the reports involves upgrade behaviors. Historically, most consumers have not upgraded their PCs with new OSes -- though Mac users and some technophile consumers have been an exception on this count.  Instead, the majority of consumers have acquired new OSes when they purchase their new PC.  These are known as "replacement cycle upgrades." 

With Windows 7, however, upgrade behavior was much stronger.  Why?  In short, Windows 7 is a thinner client program than was Windows Vista, meaning that it works well on older hardware configurations.  In the past, OSes were designed with Moore's Law as an underlying assumption -- that is, that newer PC hardware would be significantly faster and more powerful than the previous generation's hardware. Windows 7, however, is a less burdensome OS than Windows Vista.  The rise of Netbooks, the physical assets of multi-PC households, and an attachment by many consumers to their Windows XP machines all contributed to the need for a sleeker, thinner Windows OS, which Windows 7 delivered. 

Among early adopters of Windows 7, in Q4, for the first time upgrading behavior matched replacement cycle purchasing, as this Figure shows:

Capturing The Unconscious

Reineke Reitsma

Last week, I attended Research 2010, the research conference organized by the UK's Research Organization. One session was on innovative research methodologies, and although it's not completely new to the industry, I was surprised to see two of the presentations covering research methodologies that capture people's unconscious behavior through technology.

The first was a presentation about lifelogging, or “glogging” for those in the know. Simply put, lifelogging documents somebody's life through technology worn by the “respondent.”

Bob Cook from Firefish presented how this technology helps researchers better understand the tradeoffs that people constantly make. Lifelogging has a long history, and it was started by Steve Mann. In the early 1980s, he walked around with recording gear that looked more like a suit of armor.
