ABSTRACT:
A method to process database queries are disclosed. One embodiment comprises receiving an abstract query against a database having a multiplicity of data records. The abstract query identifies a model entity that defines a focus of the abstract query. The method further comprises receiving a limitation request configured to restrict a result set for the abstract query. The limitation request specifies a limitation on data records that are returned for one or more instances of the underlying model entity. From the abstract query, an executable query capable of being executed by a query engine is generated. The executable query is modified on the basis of the limitation request. The modified executable query is executed against the database to obtain the result set, whereby the result set is restricted as requested by the limitation request.
