  abstract      = {This paper presents a strategy for the support of global object identifiers in the Donají multidatabase environment. The strategy includes the internal representation for object identifiers and the methods for identifying related objects from heterogeneous sources. We present a classification for objects and their identifiers as permanent, temporary, and virtual objects. The use of different types of identifiers allows the query processor to promptly identify the source and the mapping function for locating distributed objects. When relating entities retrieved from different sources into a common global identifier, the global identification approach applies functions that determine the degree of equality between the local entities. Objects in Donají can be related as either exact, equivalent, or compatible objects. The Donají approach to global object identification provides integrated support for non-disjoint data sources, the specification of user-defined map-ping functions and the specification of relationships between related objects at different levels of equality.}
