From the homepage:
Teiid is a data virtualization system that allows applications to use data from multiple, heterogenous data stores.
Teiid is comprised of tools, components and services for creating and executing bi-directional data services. Through abstraction and federation, data is accessed and integrated in real-time across distributed data sources without copying or otherwise moving data from its system of record.
- Query Engine: The heart of Teiid is a high-performance query engine that processes relational, XML, XQuery and procedural queries from federated datasources. Features include support for homogenous schemas, hetrogenous schemas, transactions, and user defined functions.
- Embedded: An easy-to-use JDBC Driver that can embed the Query Engine in any Java application. (as of 7.0 this is not supported, but on the roadmap for future releases)
- Server: An enterprise ready, scalable, managable, runtime for the Query Engine that runs inside JBoss AS that provides additional security, fault-tolerance, and administrative features.
- Connectors: Teiid includes a rich set of Translators and Resource Adapters that enable access to a variety of sources, including most relational databases, web services, text files, and ldap. Need data from a different source? A custom translators and resource adaptors can easily be developed.
Teiid 8.2 final was released on November 20, 2012.
Like most integration services, not strong on integration between integration services.
Would make one helluva component for a topic map system.
A system with an inter-integration solution mapping layer in addition to the capabilities of Teiid.
