RESUMO

An analysis over existing object models of OODBSs (Object Oriented Database System) shows the absence of a standard. This flaw limits the portability and interoperability of OODBSs, harming its endorsement, therefore demotivating its use in the market. Aiming for a solution to the problem this work proposes a reference object model and the corresponding formalism. The reference object model is compatible to the proposed standard ODMG- 93. Therefore, a standardized solution is given to the divergence among current object models, The formalism developed founds the reference model, mathematically, through the set theory. This formalism is flexible and broad in such a way that it is not restricted to the reference model and, therefore, also represents the object oriented paradigm. The reference object model, through its formalism, can be used to characterize and/or map diverging object models in the context of OODBS, hence contributing significantly to improve the conceptualization of the area
