These topics provide information about accessing data resources.
The connection between an enterprise application and an enterprise information system (EIS) is accomplished through the use of EIS-provided resource adapters, which are plugged into the application server. The resource adapter plays a central role in the integration and connectivity between an EIS and an application server. It serves as the point of contact between application components, application servers, and enterprise information systems. A resource adapter must communicate with other components based on well-defined contracts that are specified by the J2EE Connector Architecture (JCA).
