An adapter service defines an operation that the adapter performs on a resource. You need to implement one adapter service template class for each resource operation the adapter supports.

For example, you might create a service template that fetches rows from a database based on a key field, and another service template that updates and inserts records into the database.

The users of the adapter define their run time adapter service nodes based on these templates. Designer provides facilities for creating, configuring, and testing adapter service nodes.
