Resource Adapters overview

Resource adapters are used to retrieve and route data. They provide access to databases, files, messaging systems, enterprise applications and other data sources and targets.

Each adapter includes a set of adapter commands that can be used to customize its operation. Use the adapter commands to specify different queues and queue managers, specific messages by message ID, specific sets of messages with the same message ID, message descriptors in your data, and more.

Resource adapters answer the questions Where should the data come from? and Where should the data go?

The resource adapters provided with the HCL Link products enable data transformation and adapter-specific behavior recognition on different systems and data structures.

Source and target data may be in a file, from a specific application, in a database, from a message queue, from an archive file, or from other sources. The client components of HCL Link, maps, and schemas are integral to using the resource adapters.

Each input of data and each output of data requires content definition settings. These card settings are specific to input and output cards, although some settings are common to both cards.

You can also develop your own adapters, enabling new types of data sources and targets, by using the open adapter interface provided in HCL Link and in the HCL Link Software Development Kit.
