Presentation: "XML Persistence"

Track: High Performance, Scalable

Time: Monday 11:30 - 12:20

Location: Store Sal

Abstract: For decades the centre of the enterprise was the relational database; everything had to eventually communicate with the database. Many of the technologies even as recently as ten years ago were database centric, EJBs for example. It's fare to say that XML was in it's very earliest stages at the turn of the millennium, it existed but we were still struggling with DTDs. Today it's difficult to imagine an enterprise without some form of XML, most of today's systems, both internal and external send and receive hierarchical messages, usually in XML. Even niche standards like SWIFT are hierarchical in structure. The problem with all this is the impedance mismatch between hierarchical messaging and relational persistence. Object-Relational Matching (ORM) provides a good solution at the simplistic level and solves many problems but is incredibly time consuming and leaves a static binding between the ever-changing message and static relational database as things get more complex. Squeezing hierarchical messages into relational databases with ORM is costly and not maintainable in the long term. This talk explores several ideas for persisting hierarchical data.

Presentation: "Cloud Panel Discussion"

Track: Cloud

Time: Monday 15:40 - 16:30

Location: Lille Sal

Abstract: The premise is simple. In the future, we won't have or even need all our data or software programs on our own computers -- they'll be floating around somewhere on somebody else's servers, accessible via the internet. A vast, interconnected "nebula" of other people's data and servers, aka the "Cloud". Is this Web 3.0, SOA 2.0, something entirely different, or the same old stuff once again repackaged by the marketing department? Listen to our industry experts' views and opinions (they are sure to have many!) as they debate what it means to live in the cloud. Conferences are all about interaction, so please come and interact with us by posing questions to the panel.
