Metadata Services for Distributed Event Stream Processing Agents

Enterprise-level applications are becoming complex with the need for event and stream processing, multiple query processing and data analysis over heterogeneous data sources such as relational databases and XML data. Such applications require access to the metadata information for these different data sources. This paper discusses the design and implementation of a servicebased dynamic metadata repository over heterogeneous data sources in a distributed event stream processing environment. The metadata repository is dynamic such that data resources can be registered or unregistered at run time. The design of such a metadata database is the first step in researching multiple query optimization over various query expressions to detect and materialize common subexpressions over relational and XML structured data sources.
