Abstract:
Streams processing has been focused on the execution of a relatively small amount of potentially complex queries. Not enough attention has been given to the requirements of business environments. In these environments, changes to databases represent the most important data streams. Furthermore, streams have to be checked against potentially millions of continuous queries. Program failures, system failures, and schema changes have to be invisible to end-users. Processes (agents) associated with continuous queries have to survive system failures as well. Information has to be distributed according to user specifications, with full auditing support for business critical information. The presentation will discuss these challenges in detail and discuss database product features supporting these new business requirements.
Speaker Bio:
As member of IBM's IMS development team, Dieter proposed, architected, and implemented products that enabled high-end transaction technology. This work originated many of the core concepts of database/transaction technologies. While working for Ahmdahl (Fujitsu), Dieter worked on I/O optimization (Electronic data store, RAID5 technology). While at Digital (HP), Dieter led the development of the first database based workflow system. After joining Oracle, Dieter architected the first message queuing system that is fully integrated into a commercial database - Oracle/AQ (Advanced Queuing). A more recent achievement is the support of ''Expressions as Data' in ORDBs, which is a basic building block for event based computing. Dieter has the MS equivalent from the University Muenster (Germany). He has published a series of articles, holds various patents, and served on many conference and workshop program committees.
