Red Hat Training

A Red Hat training course is available for Red Hat JBoss Data Virtualization

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:
  1. a translator (mandatory) and
  2. 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.
