"Data services and rich Internet applications are improving the usability and efficiency of browser-based applications," says Jeff Vroom, Principal Scientist as Adobe and one of the distinguished speakers at DataServices World 2008 West in San Jose, California on November 20, at The Fairmont Hotel.

By moving more logic to the client, using more efficient programming languages, and more functional runtime environments, end users - says Vroom - get to experience the functionality of a desktop application deployed as a Web application.

However, in his session - "LiveCycle Data Services: Declarative Data Management for SOA and Web Applications" - he will point out that developers face additional challenges:

"Data must be copied to the client, application logic must be split between client and server, and validation logic often must be performed on both the client for usability and on the server for security."

Using Adobe’s Flex environment and Adobe LiveCycle Data Services (LCDS), Vroom will be showing how clients can integrate data from disparate sources and execute high-level object based queries that return objects in their domain model.

"UI controls are bound to the data with just a couple of lines of code to both query and display the resulting data," notes Vroom. "You can enable on-demand paging of large data sets, lazy fetching of associated objects, and track and persist changes made to the data on the client. Built on LCDS’s real time channel infrastructure, client’s views of the data are kept in sync automatically. "

His session will present an overview of the design and architecture and provide a high-level walk through of building an LCDS application.

DataServices World, being held November 20 in San Jose, California, at the 14th International SOA World Conference & Expo, has a lineup of speakers headlined by Dr Mike Carey (pictured), one of the 50 Most Influential Computer Scientists in the world. The lineup also includes experts from Adobe, Yahoo!, IBM, Oracle, m2mi, and DataDirect Technologies.

"DataServices World is about the confluence of databases, data warehousing, business intelligence, enterprise computing and Internet computing," says Ken North, DataServicesWorld 2008 West Conference Chair.

Carey, who leads the lineup, is Bren Professor of Information and Computer Science at UC Irvine and the 2005 recipient of the ACM IGMOD Edgar F. Codd Innovations Award - the computing equivalent of an Academy Award!

Carey, a National Academy of Engineering member, is acknowledged as one of the 50 most influential computer scientists in the world by a UCLA-maintained Web site that tracks research citations. He is best known for his work on advanced database systems and database system performance.

His most influential academic projects have been the EXODUS and SHORE database systems, which continue to influence designers and researchers in the field. In industry, he contributed to IBM’s DB2 Universal Database system and played a leadership role for BEA Systems’ data integration and management solutions. These systems are widely used in the banking, insurance and healthcare industries, and they also have many government applications.

Speaking of the much-acclaimed DataServices World event, which kicked off in March of this year in New York City, Ken North said of Data Services as a technology approach: "Its focus is architectures and technologies for accessing data from heterogenous data sources and providing that data to consumers such as components, services and applications."

North continued:

"Many organizations have a variety of persistent data stores, including SQL databases, geo-coded data files, spreadsheets, content management systems and XML. Services, applications, and mashups can consume and integrate data from disparate data sources. In an n-tier enterprise architecture and a service-oriented architecture, the logic for providing data from databases and other data sources resides in data access layers and data services layer."
