A great deal of effort has been spent by the database community towards consolidating object-oriented concepts, especially from the mid 1980s. Even though improvements in understanding and formalizing such concepts have been achieved, there is still a long way to go before an object-oriented technology is developed to the extent of the relational one. The difficulties in finding a common ground for developing object-oriented systems come mostly from the lack of formal foundations as compared to the relational model. Therefore, research in this area has usually led to building object-oriented systems with different underlying conceptual models rather than a common one, as it is in the relational approach. Hence, a formal data model capable of an easy mapping to those models is necessary. Such a model should incorporate basic modeling concepts such as E-R and be flexible and extensible as well. This paper proposes KBZ+ as a data model, based on the Z specification language to yield the above requirements. |
