Abstract
Embodiments of the invention provide techniques for determining query entities in physical tables for an abstract database. A query entity may be created to store a particular set of data. The query entity may be defined in terms of the structure of the physical database, such as an SQL statement, used to generate the query entity as needed. The fields included in a given query entities may be determined based on the presence (or absence) of values in the columns of a physical database table. In addition, logical fields having access method which map to the fields included in a query entity may be generated.
