Towards a Comprehensive View of Object-Oriented Play

A View Mechanism for Object-Oriented Databases

In June 1997, an international workshop on engineering of federated database systems has been held in Barcelona in conjunction with the 9th Conference on Advanced Information Systems Engineering (CAiSE'97). This paper reports on the results of this workshop and summarises the identi ed open issues for future research in this area.

Towards a Unified View of Petri Nets and Object Oriented Modeling

The present work presents a preliminary proposal of unification between classical Petri Nets and objects based on two classes: the activity class and the box class. Eventually one of them can be interpreted as passive or active object, but both can equally contain attributes and methods specified by net formalism. So far, the result is a classical net formalism where each component is an object...

Towards a Deductive Object-Oriented Database Language

A language for databases with sets, tuples, lists, object identity and structural inheritance is proposed. The core language is logic-based with a xpoint semantics. Methods with overloading and methods evaluated externally providing extensibility of the language are considered. Other important issues such as updates and the introduction of explicit control are discussed.

Towards an Object-Oriented Curriculum

r s This proposal suggests a redesign of the teaching of programming and othe oftware topics in universities on the basis of object-oriented principles. It argues t that the new ‘‘inverted curriculum’’ should give a central place to libraries, and ake students from the reuse consumer’s role to the role of producer through a process of ‘‘progressive opening of black boxes’’. ____________________...
