A back-end service adaptation system provides access to normalized data in a data repository for a consumer runtime environment sending a query request for denormalized data. The back-end service adaptation system can include a data access service layer, a parser layer, and a back-end service adaptation runtime layer. The consumer runtime can use a service adaptation definition language (SADL), and the parser and data access service can be configured to convert and translate the SADL request for the back-end service adaptation runtime layer.
