European SQLAdria Seminar – Dubrovnik 2015 Enterprise-grade Hybrid Transaction/Analytical Processing
Bringing data to analytics or analytics to data? The former has been the practice for a long time, not necessarily because the application model has required so. The reason is that the available technology supported only clearly 
separated, workload-optimized systems that specialized in transactional or in analytical processing, but not in both. The technology advancements in more recent years allowed a new look at the old dilemma and the database 
management systems providers are coming up with new offerings that promise to enable bringing analytics to where the data is created, to transactional systems. In this presentation we will look closer at the business and technology drivers behind this shift and present technical details of the System z approach to the challenge, including the latest news from the IBM DB2 Analytics Accelerator development.

SQLAdria Seminar – Dubrovnik 2012 Trends and Directions in Database Technology

Relational database technology has become a key element of most enterprise IT architectures over the course of the last 25 years. During that period of time, relational database products like DB2 have evolved significantly to address the changing technology and business needs of customers. This evolution has come in the form of dramatic improvements in performance, scalability, availability and system management.The evolution has also introduced major functional enhancements to the relational database products that represent significant departures from the original concepts described by Dr. Codd in his seminal research. For example, customer demand for object database features in the 1990′s caused relational products like DB2 to introduce stored procedures, user-defined functions, and triggers as a vehicle for customizing the behavior of the relational database engine. More recently, most of the major relational products have evolved to include native data stores and query language enhancements to handle XML.
 In the past few years, a number of new database technologies have been introduced: in-memory data stores, graph stores, column stores, name/value stores, etc. Some industry pundits have proclaimed that these technologies represent the end of the relational database era. In this session, we will discuss some of these new technology developments, and describe some of the work that is being done within IBM to continue the evolution of DB2 to address these new technology and business needs.

SQLAdria Seminar – Dubrovnik 2007 SOA - enabling Your Mainframe Data

Service Oriented Architecture is a key enabler for structuring and connecting IT systems in a flexible manner that maps closely to the needs of the organization. SOA often means different things for different participants in the IT ecosystem, but its data aspect is of a crucial importance irrespective of the individual views. In developing SOA solutions, ignoring the state of organization?s data risks exposing data that could be misinterpreted, incomplete, or in some cases, wrong. Data and their inter-relationships are complex, and require understanding and interpretation to expose what is really needed and relevant. A vast amount of business data is managed by mainframes. SOA enables augmenting the value of that data and getting even more from the traditionally rich, secure and highly available computing infrastructure. This presentation will provide an overview of different techniques to unlock the additional value of your mainframe data in the SOA world.
