A method and apparatus for generating references to a set of objects which reside in a plurality databases is described. Each object is associated with a table from a plurality of tables that are contained in the plurality of databases. An object id is associated with each object; the object id uniquely identifies the object relative to the objects in the set of objects. A table id is associated with each table; the table id uniquely identifies the table relative to tables in the plurality of tables. A table containing an object is located based on the table id associated with the table, and the object is located in the table based on the object id associated with the object. A table mapping is generated. The table mapping maps a set of tables to databases associated with the set of tables. The set of tables are from the plurality of tables. References to objects from the set of object are generated. Each reference comprises data that identifies an object. The reference contains data representing the object id of the referenced object, the object referred to by the reference. The reference also contains data representing the table id of the table containing the referenced object. An object is located based on the table mapping and the reference referring to the object. The table containing the object is located based on the data in the reference, the data representing the table id associated with the table containing the object.

[ What is claimed is:] [1.] In a computer system, a method of locating an object that belongs to a set of objects that reside in a plurality of databases, the method comprising the steps of:associating an object id with each object from said set of objects, wherein each object from said set of objects is contained in a table from a plurality of tables, wherein said plurality of tables are from said plurality of databases;associating a table id with each table of said plurality of tables;wherein the table id associated with each of said plurality of tables is not assigned to any other table in any of said plurality of databases;locating a table that contains said object based on the table id that is associated with the table that contains the object; andlocating said object within said table based on the object id that is associated with said object.
