Listening to Don Haderle, IBM Database Guru

Last night, I had the privilege of listening to my old-time colleague from IBM, Don Haderle at a meetup in Mountain View. Don retired from IBM in 2005 after a distinguished career spanning almost 4 decades. He was an IBM Fellow, the biggest honor given to technical leaders. He was the key architect/developer of IBM’s mainframe DB2 product when I was a product manager in the same team. Subsequently Don became the CTO of the Data Management division before retiring. Last evening he spoke on the evolution of the database business since the 1960s, lessons learnt,  and what lies ahead in the next five years.

His main points were:

- Most of the data used to be internal to enterprises, but now most of that is external data

- Enterprises need a federated data architecture to deal with this mix

- Nothing ever goes away in this business. Model 204, a database from the 1960s is the primary data source for IRS (all our tax records). IMS Fast Path still runs major banking in Japan and other countries.

- Key-Value store and a two-level hierarchy was how we started the database business. Now it feels like Back to the Future. Relational databases had little to do with the relational model. They gained popularity because of the application backlog problem that existed before. Programmers could build apps. much more quickly than the earlier era.

- New databases are addressing two needs – need for easy extension to varieties of data (dynamic schema) and elasticity (expand/contract to address scale and performance).

- every database starts out as a simple thing, then they get bulkier and more complex. All the user defined data types stuff in RDBMS never got used.

- although many of the current technology in NoSQL and newSQL seems old (KV store with indexing, massively parallel processing, replication, partitioning,..) their time has come given the massive growth of devices and data combined with the available bandwidth and processing power. Smartphone traffic in 2012 was 885 petabytes per month – a 70% growth rate year to year. There is a need to analyze this in real-time, integrated with social media, structured data, and more to satisfy many business opportunities. Within this set of data, the information models (data packet descriptions) increased 10-100fold. We see similar trends in medical, gaming, scientific, and myriad other sectors. 

- the new database will become a platform addressing multitude of demands – deep-dive analytics, specialized customer-facing applications, etc.

- Role of the DBA will be “reactive” and the software developer will lead the change.

It was wonderful listening to Don. He truly is one the best in our industry – lots of wisdom, wit and humor. At a personal level, it was nice to catch up with him after many years.

IoT & Smart Cities Stories
The deluge of IoT sensor data collected from connected devices and the powerful AI required to make that data actionable are giving rise to a hybrid ecosystem in which cloud, on-prem and edge processes become interweaved. Attendees will learn how emerging composable infrastructure solutions deliver the adaptive architecture needed to manage this new data reality. Machine learning algorithms can better anticipate data storms and automate resources to support surges, including fully scalable GPU-c...
Machine learning has taken residence at our cities' cores and now we can finally have "smart cities." Cities are a collection of buildings made to provide the structure and safety necessary for people to function, create and survive. Buildings are a pool of ever-changing performance data from large automated systems such as heating and cooling to the people that live and work within them. Through machine learning, buildings can optimize performance, reduce costs, and improve occupant comfort by ...
The explosion of new web/cloud/IoT-based applications and the data they generate are transforming our world right before our eyes. In this rush to adopt these new technologies, organizations are often ignoring fundamental questions concerning who owns the data and failing to ask for permission to conduct invasive surveillance of their customers. Organizations that are not transparent about how their systems gather data telemetry without offering shared data ownership risk product rejection, regu...

Poor data quality and analytics drive down business value. In fact, Gartner estimated that the average financial impact of poor data quality on organizations is $9.7 million per year. But bad data is much more than a cost center. By eroding trust in information, analytics and the business decisions based on these, it is a serious impediment to digital transformation.
Digital Transformation: Preparing Cloud & IoT Security for the Age of Artificial Intelligence. As automation and artificial intelligence (AI) power solution development and delivery, many businesses need to build backend cloud capabilities. Well-poised organizations, marketing smart devices with AI and BlockChain capabilities prepare to refine compliance and regulatory capabilities in 2018. Volumes of health, financial, technical and privacy data, along with tightening compliance requirements by...
Predicting the future has never been more challenging - not because of the lack of data but because of the flood of ungoverned and risk laden information. Microsoft states that 2.5 exabytes of data are created every day. Expectations and reliance on data are being pushed to the limits, as demands around hybrid options continue to grow.

Enterprises have taken advantage of IoT to achieve important revenue and cost advantages. What is less apparent is how incumbent enterprises operating at scale have, following success with IoT, built analytic, operations management and software development capabilities - ranging from autonomous vehicles to manageable robotics installations. They have embraced these capabilities as if they were Silicon Valley startups.
As IoT continues to increase momentum, so does the associated risk. Secure Device Lifecycle Management (DLM) is ranked as one of the most important technology areas of IoT. Driving this trend is the realization that secure support for IoT devices provides companies the ability to deliver high-quality, reliable, secure offerings faster, create new revenue streams, and reduce support costs, all while building a competitive advantage in their markets. In this session, we will use customer use cases...
