Abstract
A method and apparatus for obtaining an identifier of a logical unit of data that belongs to a database. In one embodiment, a method of obtaining a first identifier of a logical unit of data that belongs to a database is described. The first identifier uniquely identifies a location of the logical unit of data within the database, and the method includes determining a group of identifiers that includes the first identifier based upon information, concerning a structure of the database, that does not directly specify the group of identifiers. In one aspect of the present invention wherein the logical unit of data has an application space label which can be used by application programs to access the logical unit of data from the database, the method obtains the first identifier without first accessing the logical unit of data from the database using the application space label.
