Slides for Briefing Room webcast ( https://bloorgroup.webex.com/bloorgroup/lsr.php?RCID=869f964b1380f728cedde802779a1e12 )
Organizations worldwide are learning hard lessons these days about the constraints of dated information systems. The time-tested process of Extract-Transform-Load (ETL) is fast losing its ability to cope with the volume, velocity and variety of Big Data coming down the pike. Forward-thinking companies are therefore prepping the battle field by designing on-ramps to the future of streaming analytics. Register for this episode of The Briefing Room to hear Analyst Mark Madsen explain how a new era of data solutions is rising to the challenge of streaming data. He'll be briefed by Steve Wilkes, founder and CTO of the Striim platform. Steve will share how enterprises are turning to streaming data integration, in-memory transformations and continuous processing to achieve the goals of ETL in milliseconds – at a fraction of the cost and complexity of legacy systems. Several case studies will be shared.

  • I like this however IT people too big morons in general just looking at vested products, a big elephant (Hadoope) is the favourite discussion topic in EU currently. Big Data is a BIg problem how do you build analytical models for several thousand parameters?Bottom Line: YOU CAN'T. Hence we should connect and discuss about MODEL-FREE analytics. Kind regards

Flowing Persisted Sliding window of “now” Persisted but not yet loaded into a platform Queryable history Managed history Streaming isn’t either‐or, it’s part of core architecture A DB or ETL can get you to within minutes (at large scale) but it won’t be easy or cheap; mainly lives in the realm of history Event streams, in-mem stores, CEP streaming SQL can be used for these Real time monitoring doesn’t use only real time data: windows, restarts, detecting deviation, so the above boundaries are crossed.

About Third Nature Third Nature is a research and consulting firm focused on new and emerging technology  and practices in analytics, business intelligence, and performance management. If your  question is related to data, analytics, information strategy and technology infrastructure  then you‘re at the right place. Our goal is to help companies take advantage of information‐driven management  practices and applications. We offer education, consulting and research services to  support business and IT organizations as well as technology vendors. We fill the gap between what the industry analyst firms cover and what IT needs. We  specialize in product and technology analysis, so we look at emerging technologies and  markets, evaluating technology and hw it is applied rather than vendor market positions.
