1.2. Red Hat JBoss Data Virtualization Connector Architecture
The process of integrating data from an enterprise information system into Red Hat JBoss Data Virtualization requires one to two components:
- a translator (mandatory) and
- a resource adapter (optional), also known as a connector. Most of the time, this will be a Java EE Connector Architecture (JCA) Adapter.
A translator is used to:
- translate Red Hat JBoss Data Virtualization commands into commands understood by the datasource for which the translator is being used,
- execute those commands,
- return batches of results from the datasource, translated into the formats that Red Hat JBoss Data Virtualization is expecting.
A resource adapter (or connector):
- handles all communications with individual enterprise information systems, (which can include databases, data feeds, flat files and so forth),
- can be a JCA Adapter or any other custom connection provider (the JCA specification ensures the writing, packaging and configuration are undertaken in a consistent manner),
Note
Many software vendors provide JCA Adapters to access different systems. Red Hat recommends using vendor-supplied JCA Adapters when using JMS with JCA. See http://docs.oracle.com/cd/E21764_01/integration.1111/e10231/adptr_jms.htm - removes concerns such as connection information, resource pooling, and authentication for translators.
With a suitable translator (and optional resource adapter), any datasource or Enterprise Information System can be integrated with Red Hat JBoss Data Virtualization.
