Abstract
Generally described, embodiments of the present invention provide the ability to assign primary keys and foreign keys to lists of any number of sites that are maintained by a database hosting service. More specifically, a scalable table, like the master table described below, may continue to be used without specifying primary keys or foreign keys within the table by using two additional tables in which the keys are specified for each list of each site. Integrity may be maintained by confirming that all changes to either a primary key or foreign key are appropriate before applying the changes to the master table.
