Teiid is a data virtualization system that allows applications to use data from multiple, heterogeneous 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.

Embedded An easy-to-use JDBC Driver that can embed the Query Engine in any Java application.

An enterprise ready, scalable, manageable, runtime for the Query Engine that runs inside JBoss AS that provides additional security, fault-tolerance, and administrative features.
