The BEA AquaLogic data services platform (Demo)

We showcase the BEA AquaLogic Data Services Platform (ALDSP), a middleware infrastructure product that enables the declarative development of data services for service-oriented architectures (SOA). ALDSP includes support for modeling networks of interrelated data services, for realizing data services using either graphical or source-based XQuery editors, for testing data services as they are developed, and for identifying and incorporating changes in the structure of the underlying sources of data. Physical data sources supported include relational tables and views, Web services, packaged applications, stored procedures, XML files, delimited files, and custom Java applications. Data service definitions can be layered; as with relational views, such layering is virtual, and is rewritten away at query compilation time. ALDSP supports both read and update data service functions, and the ALDSP XML query runtime includes a number of interesting query operators and distributed query optimizations. In addition, ALDSP supports function caching, fine-grained security, and SQL-based data access as well as providing service-based and XQuery access to SOA data. We plan to demonstrate as much of this as time permits.
