1. Apparatus for specifying a class of parameterized information requests and making instances of parameterized information requests that belong to the class, the apparatus being implemented in a system having a processor and data storage accessible to the processor and the apparatus comprising: objects in the data storage including a connector object in the data storage that represents the class of parameterized information requests; a request parameter object in the data storage that defines a request parameter for parameterized information requests belonging to the class, the request parameter comprising a bind parameter that is replaced by a bind value before the requested parameter is used in an instance of a parameterized information request; and an information source access object in the data storage that specifies attributes of an information source which will receive the instances of the parameterized information requests that belong to the class, the processor responding to an input specifying creation of an instance of the class of parameterized information requests represented by the connector object by using the request parameter defined in the request parameter object and the attributes of the source of information to make the instance of the class.
