Sonic XML Server
Progress Technologies
Sonic XML Server ™ is a set of high-speed processing, storage and query services for XML documents required to manage Sonic ESB operational data. By processing XML messages in native XML format, XML Server is very fast and does not place restrictions on the XML message schema. The advent of Extensible Markup Language (XML), a true hardware and software independent data format, was a revolutionary step forward. Because XML describes information independently of a specific system or application data formatting rules, XML is a key technology for supporting flexible exchange of heterogeneous data. However, this flexibility can take a lot of time and resources to process the XML format. Sonic XML Server provides fast processing of operational data and storage of XML messages required to efficiently implement a service-oriented architecture. Sonic XML Server extends and enhances Sonic ESB's XML message processing model by providing native query, storage and processing services. -

Enterprise information systems have dramatically changed and progressed. Management environment has largely changed by corporation merger, internal control and regulatory compliance control for personal information protection. New business is launched because of tough competition. New system to support decision making is constructed. Systems are improved in existing business to increase profit. As a result, various systems exist in silos of different departments that are operated and managed separately. Such situation cause not only increased overall system maintenance cost but also diminished enterprise management efficiency. Enterprise information systems require "highly adaptable" and "highly flexible" system architecture and implementation. Service Oriented Architecture (SOA) is focused from such demand. And Enterprise Service Bus (ESB) is the SOA integration technology that provides a unified architecture for high reusability.
