Providing clients with services that retrieve data from data sources that do not necessarily support the format required by the clients

   
   

A method and system for allowing clients to retrieve data from data sources that do not necessarily support the same protocols and formats as the clients. The clients issue service requests. A pre-processor responds to the requests by generating XML-structured request objects with unresolved links to the data sources that have information required by the clients. An XML processor resolves the links by issuing requests through one or more gateways. The gateways convert the responses received from the data sources into XML, which the XML processor uses to create XML composite response documents. A post-processor filters the XML response documents, and applies XSL stylesheets to transform the XML composite response documents into client-specific responses that conform to the format required by the clients. The client-specific responses are then sent to the clients.

Um método e um sistema para permitir que os clientes recuperem dados das origens dos dados de que não suportam necessariamente os mesmos protocolos e formatos que os clientes. Os pedidos do serviço da edição dos clientes. Um pre-processor responde aos pedidos gerando objetos XML-estruturados do pedido com ligações não resolvidas às origens dos dados de que têm a informação requerida pelos clientes. Um processador de XML resolve as ligações emitindo pedidos através de um ou mais passagem. As passagens convertem as respostas recebidas das origens dos dados de em XML, que o processador de XML se usa criar originais compostos da resposta de XML. Um post-processor filtra os originais da resposta de XML, e aplica stylesheets de XSL para transformar os originais compostos da resposta de XML nas respostas cliente-específicas que se conformam ao formato requerido pelos clientes. As respostas cliente-específicas são emitidas então aos clientes.
