  • receiving a selection, from a plurality of filtered fields, of a first field to be included in an abstract query, the plurality of filtered fields defined in an abstraction model that models underlying physical data in a manner making a schema of the physical data transparent to a user of the abstraction model;

    determining one or more physical columns storing at least one value defining the first field;

    identifying, from the plurality of filtered fields, one or more filtered fields defined by one or more values stored in the one or more physical columns;

    presenting the one or more filtered fields to a user;
