It is not reasonable to consider that a single data model can be adequate for any application/There are many data models;each of them has its advantages and drawbacks. Building up an other model does not make sense in...

Up till now, a few secure models of objectorienteddatabases have been proposed. Most of them support multilevel entities and more or less cover stories. In this paper, we undertake a more natural approach to model o...

Complex physical systems require the support of data models to define and manipulate the data generated during simulation. These models should have the expressive power to represent the static and temporal relationships among data and they should have the capability to initiate actions to enforce these relationships when the application state is changed. Most commercial databases are passive, i.e., they do not take action or enforce a constraint when the data undergoes a state change. objectoriented database systems have taken the technology one step further by encapsulating operations with the data. In this paper we propose a data model for simulation which builds on objectoriented and active database principles to represent physical systems in terms of its structure and function. This model is called the structure-function paradigm, or SF-paradigm for short.
In this paper, we present a framework based on the notion of classes as an organizational tool to model some common concepts in Database. The creation of a simple and representational model helps to reconcile the seem...

We argue that a fully object-oriented database management system is a very suitable basis of every modern CASE environment. We describe how the features provided by an OODBMS are exploited to build a CASE tool or envi...

It is argued that future applications will require integrity of complex, persistent data in the face of hardware and program failures. We discuss Thor, a new object-oriented database, which offers a computational mode...
