1. A method for simplifying object mapping for an external interface for a computer system, comprising: performing processing associated with receiving a client request for action from the external interface, the external interface comprising a human being or a computer program; performing processing associated with associating the client request to a logical object in order to minimize a representational gap between the client request and a physical object using the logical object, wherein the associating comprises accepting an entity identifier and a property name and validating that the client request is a query request, wherein the logical object comprises a dialogue process and a collection of metadata that describes an entity definition, wherein the dialogue process comprises a query subroutine comprising the query request and processing the query request to return a dialogue response, wherein the dialogue response comprises a list of dialog records of corresponding values from the physical object if a successful query occurs, and a redirection is returned if a non-successful recoverable query occurs, the dialogue response also comprises a value comprising: value, exception, or the redirection, wherein the redirection is constructed with the entity identifier to a new dialog model that can be used to recover from an error; performing processing associated with converting the logical object to a physical object that resides in an object relational mapping using information from the query request; performing processing associated with mapping between the physical object that resides in the object relational mapping and a database; and performing processing associated with responding to the query request using the object relational mapping in order to simplify the external interface by minimizing the representational gap between the external interface and the physical object using the logical object.
