HydraData components automate the creation of high performance, service-oriented data services in Java and C++, as well as expose heterogeneous data sources as lightweight, independent, and decentralized data services.

HydraSDO for XML provides a data access service for parsing XML data and populating a DataGraph consisting of DataObjects and a change summary. An application retrieves a DataGraph from a data source using the HydraSDO API in either Java or C++, modifies the data graph as required and applies any changes back to the original data source through the Data Access Service. The XML data is parsed just once, after which it can be navigated using XPath expressions.
