Abstract
Techniques are provided for accessing derivative properties from a database utilizing a logical schema instruction that includes a base object identifier. A logical schema instruction may be received and analyzed to identify a predefined keyword. A portion of the logical schema instruction, that is located in relation to the predefined keyword, may be identified. The portion may include a base object identifier and a property identifier, e.g., a derivative property identifier. In an embodiment, the identified portion of the logical instruction is not translated to a database schema instruction at prepare time. Instead, an extract function is executed at runtime access and analyze a database table that corresponds to a base object associated with the base class identifier. A property in the database table that corresponds to the property identifier may be identified. Advantageously, a base object identifier may be utilized to access a derivative property.
