30 Years of Innovation
DB2 customers, partners and IBMers discuss important milestones, what makes DB2 so great and why DB2 is still around today!

Don HaderleDon Haderle - Father of DB2! Parents never know how their children will turn out. But if they turn out well, then we take credit for it. DB2 for z/OS, which will be 30 years old in 2013, has turned out well, and though I'd like to think it was all because of the parents, the facts are different. First let me assert that DB2 for z/OS is heavily used by enterprises worldwide to perform database functions for core business transactions and analytics - others can provide the statistics to back this assertion. The question is why this is so for a 30-year-old technology, when a few years is a lifetime in our business. I attribute it to six critical factors:

  1. Great foundation:
  2. Customers:
  3. Integration with the Z-ecosystem:
  4. Partnership with practitioners and partners:
  5. Evolving DB2 as the world changes:
  6. Technologists:

Happy Birthday!
Don Haderle - Father of DB2

Dr. Pat Selinger, IBM Fellow and "The Mother of DB2"
More than three decades ago, as we built the research prototype that became the foundation for DB2, we were determined to prove that the relational databases were usable and could perform well. Wow! Did IBM ever prove that! DB2 has become a dynasty, with the world's leading performance, flexibility, and reliability. With its ability to enable ever richer types of data and support not only high-performance transactions but also deep analytics and data mining, DB2 provides the capabilities that are critical for Smarter Commerce®, Smarter Banking®, Smarter Manufacturing, Smarter Distribution, and the whole broad range of capabilities our customers need to build a Smarter Planet®.

Technology, and the IT industry itself, has changed significantly over the past 30 years, and despite all those changes DB2 continues to be a critical element of the IT fabric in most large enterprises. People often ask what we did in DB2 to remain relevant over such a long period of time. In my mind, the single biggest thing we did was to establish a culture in our development team that ensures that our technical leaders are deeply engaged with the DB2 customer community. Unlike some of our competitors, the key designers of DB2 are all well known by our customers. They travel to meet you at conferences and come for on-site visits at your company's place of business. Many of you have worked with the DB2 designers one-on-one to work out solutions to the technology challenges you face, and often these end up as product enhancements in the next release of DB2. Many of our customers can personally identify multiple features in DB2 that they had a hand in designing. It is this tight interrelationship with our customers that allows DB2 to meet your data storage needs, and without your help in this area we would not have enjoyed this longevity. I'd really like to take this opportunity to thank all of you for taking the time to work closely with us on these issues. It has been the single most important factor in making DB2 a successful and long-lived product.

Jeff Josten.jpgJeff Josten, Distinguished Engineer, DB2 for z/OS Development DB2 is still a vital product after 30 years mainly because of an extremely loyal and enthusiastic user community coupled with a highly skilled and experienced development team that listens and responds to customers. Another critical aspect to DB2's longevity that a lot of people probably don't appreciate is that the architectural foundations of the product are rock solid, and this allows us as the development team to easily (in most cases) extend DB2's capabilities to meet our customers' quickly evolving requirements. For this, we owe a big debt of gratitude to our product's creators, who had the foresight to understand that long lasting software must be easily maintainable and extendable. DB2 continues to succeed because it has adapted over the years to rapidly changing technology and requirements, and it is very well positioned to continue in this mode for years to come.

DB2 Version 3 partition independence for utilities changed the way and strategy for how historical information was managed . . . and it is still working right today. I also remember Roger Miller speaking at SpDUG in 2010 . . . it was a milestone for the Spanish community. DB2 is the most appropriate relational database management system (RDBMS) for the z/OS platform, capable of running any data management application - whether transactional or data warehousing or whatever. Because of the evolution of new versions and new appliance add-ons, DB2 has had, and will continue to have, a long journey in the IT world.

Frank Peterson Frank Petersen, JN Data A/S - DB2 Customer
In the history of DB2, I would like to draw two things forward: First, around 1987, Provinsbanken in Denmark announced that they moved their core banking system to DB2. The whole world watched and went to huge presentations at the Provinsbanken site to see with their own eyes. Suddenly, the community could see that DB2 meant serious business, and the reputation of "too slow" and "too unreliable" disappeared almost overnight. The second thing was the arrival of DB2 data sharing in Version 4 around 1995. This masterpiece of design set the cornerstone of the scalability in DB2 that has made it possible to get to the point where we are now.

I graduated college in 1994, and at my first job DB2 V1 fell into my lap. SQL performance consulting has been a passion of mine ever since. I love showing off the advanced technology of the optimizer and SQL features that can handle the most complex of business questions. My clients are moving more and more data and applications to DB2, not less and less, due to the sophistication and synergy of DB2 with the hardware it runs on. Appliances are the future of DB2 in the Data Explosion world, with DB2 seamlessly integrating with Netezza today and with many more appliances to come.

The milestone I remember the most is in DB2 V2.3 when packages were introduced. Working with the plans within CICS was not an easy task. With the introduction of packages, the DBA's job became much more productive. Enterprises are storing ever-increasing amounts of data that must be accessible around-the-clock. Downtime or delayed processing due to performance bottlenecks can cause more than a loss of productivity - it can mean losing customers. In today's business environment, organizations must ensure optimal performance for their databases and applications, and that's the reason why they have used DB2 as their preferred database for almost 30 years.

One of the most memorable milestones of DB2 for z/OS is the introduction of data sharing in Version 4. It makes DB2 scalable beyond the reach of any other relational database. DB2 for z/OS will be around for a long time because it's extremely reliable, cutting edge, and dollar-for-dollar cheaper than its competitors.
