A multilevel secure object-oriented data model (using the ORION data model) is proposed for which mandatory security issues in the context of a database system is discussed. In particular the following issues are deal...

Many tools and techniques exist for the modeling and analysis of computer and communication systems. These tools are often complex and tailored to a narrow range of problems. The system analysis task often requires co...

This paper discusses the introduction of explicit metaclasses à la ObjVlisp into the Smalltalk-80 language. The rigidity of Smalltalk metaclass architecture motivated this work. We decided to implement the ObjVli...

We provide a formal agenda for teaching the object-oriented paradigm in a programming language independent manner, and a tool which supports our teaching approach. Our proposal for a comprehensive study of the subject...

This paper describes various models of computational reflection in class based objectoriented language. Two different approaches are covered: the meta-object approach which supposes that every object can have a meta-...

Function minimization techniques often require values for the first partial derivatives of the function at a point. Certain techniques, such as Newton's method, require the values of the second partial derivatives...

programminglanguages for children have been limited by primitive control and data structures, indirect user interfaces, and artificial syntax. Playground is a child-orientedprogramming language that uses objects to ...

This paper presents a denotational model of inheritance. The model is based on an intuitive motivation of the purpose of inheritance. The correctness of the model is demonstrated by proving it equivalent to an operati...

We discuss several issues related to the integration of inheritance and concurrency in an object-oriented language to support fine-grain parallel algorithms. We present a reflective extension of the actor model to imp...

object-orientedprogramminglanguages support encapsulation, thereby improving the ability of software to be reused, refined, tested, maintained, and extended. The full benefit of this support can only be realized if ...
