1. A computer-implemented method of integrating a physical query statement in a data abstraction model comprising a first plurality of logical fields used to expose an underlying physical database, the method comprising: parsing the physical query statement to identify one or more output fields specified by the physical query statement; mapping at least a first one of the output fields of the physical query statement to a first one of the plurality of logical fields provided by the data abstraction model; and generating at least a first logical field for a second one of the output fields, wherein the first logical field includes an access method mapping the first logical field to the second one of the output fields.
