A method, system and article of manufacture for processing queries that are executed against a database and, more particularly, for restricting queryable data in a database to a subset of all available data in the database when a query is executed against the database is provided. One embodiment provides a logical representation of all of the available data in underlying physical entities by defining a plurality of logical fields abstractly describing data stored by the associated physical entities, receiving an abstract query comprising at least one logical field of the plurality of logical fields, retrieving at least one condition defining at least one property common to a plurality of physical entities of the queryable data, associating the at least one condition with the abstract query and, in accordance with the at least one condition, restricting the queryable data to the subset of all the available data when executing the abstract query.
