EXTENSIBLE DATA INTERFACE FOR SHARED SERVICE MODULE

摘要

A method and associated system for interfacing between a caller application and a service module. A service module builds a service module data structure pursuant to a previously received request. The request includes at least one caller application attribute describing the request. The service module data structure includes a generic service document and at least one service module attribute. Each service module attribute is stored in a relational table of the service module data structure. The requests serviced within the service module data structure, resulting in instantiating the generic service document. The generic service document is returned to the caller application. Building each service module attribute includes: constructing the generic service document and creating at least one container in the generic service document. Each container is respectively associated with each service module attribute in each mapping of at least one mapping.

1. A method for interfacing between a caller application and a service module, said method comprising:
building, by a processor of a computer system, a service module data structure pursuant to a request previously received by the processor, wherein the request comprises at least one caller application attribute describing the request, wherein the service module data structure comprises a generic service document and at least one service module attribute, and wherein the service module uses only the service module data structure such that the service module need not manipulate the at least one caller application attribute in performing the transaction; subsequent to said building, said processor storing each service module attribute of the at least one service module attribute in a relational table of the service module data structure; subsequent to said storing, said processor servicing the request within the service module data structure, wherein said servicing results in instantiating the generic service document; and subsequent to said servicing, said processor returning the generic service document to the caller application, wherein said receiving the request, said building the service module data structure, said storing each service module attribute, said servicing the request, and said returning the generic service document are performed by the service module, and wherein said building comprises:
constructing the generic service document, wherein the generic service document is configured to contain a result of the transaction performed by the service module; andsubsequent to said constructing, creating at least one container in the generic service document, wherein each container of the at least one container is respectively associated with each service module attribute in each mapping of at least one mapping, wherein each container comprises a data value for each service module attribute of at least one service module attribute of the service module data structure, and wherein a mapping table of the service module data structure comprises the at least one mapping.
