Some of the implications of providing referential and general integrity are outlined. Different query execution strategies required to support such integrity are described. SIM (the Semantic Information Manager) is an...

Conventional conceptual models like the Binary Relationship Model (also known as NIAM) or the Entity-Relationship Model do not fit well with the promising objectoriented database systems. In this paper we show that i...

Schema evolution is an important facility in object-oriented databases. However, updates should not result in inconsistencies either in the schema or in the database. We show a tool called ICC, which ensures the struc...

In this paper we describe a security model for a multilevel Secure object-oriented DAtabase (SODA). We demonstrate that the model satisfies the simple security condition and the ∗-property. Data classification is base...

We describe function materialization as an optimization concept in object-oriented databases. Exploiting the object-oriented paradigm-namely classification, object identity, and encapsulation-facilitates a rather easy...
