Fibonacci: A Programming Language for Object Databases
[chapter]
2000
Fully Integrated Data Environments
Preserved Fulltext
Fibonacci is an object-oriented database programming language characterized by static and strong typing, and by new mechanisms for modeling databases in terms of objects with roles, classes, and associations ...
A brief introduction to the language is provided to present those features, which are particularly suited to modeling complex databases. ...
Why an Object-Association Data Model? The object-association data model extends the object-oriented data model with a specific construct to model associations. ...

The notion of associations is motivated and presented. This kind of association is seen as first class a concept in notations at both modeling and programming level. ...
Among others the association support evolution of systems by adding descriptions and instantiations of associations to executing systems. ...
Finally we give a schematic outline of our notion of associations.
Object-Centric Modeling The notion of associations is already available in object-oriented modeling. ...

It also introduces a conceptual model for associations which is used as a baseline for comparing the four approaches to formal specification of associations. ...
Review of associations in object-oriented methods Object-oriented methods propose two distinct semantics for associations. ...

In this paper, we propose a novel access control model: The Role-Oriented Access Control Model (ROAC), which is based on the concepts of RBAC but inspired by the object-oriented paradigm. ...
Existing RBAC models suffer from two main shortcomings; lack of expressiveness of roles/permissions and ambiguities of their hierarchies. ...
Roles and permissions in ROAC are analogous to objects in object oriented programming languages. Like objects, roles and permissions can hold data (variables) and operations (methods). ...

We define the notion of role-based object behaviour and show how we integrated it into an existing object database extended with a notion of collections to support object classification and role modelling ...
We present a metamodel that enables specific services to be associated with objects based on collection membership and show how such a model supports flexible runtime configuration of loosely coupled services ...
The behaviour of an object is defined through a combination of intrinsic and extrinsic behaviour with methods in the object class defining the former and services associated with object roles defining ...

Conceptual modeling is the defining characteristic of object-orientation and provides a unifying perspective and a pedagogical approach focusing upon the modelling aspects of object-orientation. ...
We have identified conceptual modeling as a lacking perspective in the suggestions for CS1. ...
The conceptual framework is comprehensive; for CS1 we restrict the coverage to association, composition and specialization which by far are the most used concepts in object oriented modeling and programming ...

In this paper, the goal is to define a suitable behavior model based on executable specifications to allow the validation of distributed object frameworks. ...
Section 1 gives a more precise description of these features and presents the way they are considered in the proposed behavior model. In terms of validation involvement of users is the key point. ...
A typical example is the role model collaboration view of the object oriented role analysis and modeling (OOram) software engineering method [14] . ...

In this paper, we introduce a concept of roles in order to support the transition in a systematic way and thereby improving the agent-oriented modeling process. ...
The agent-oriented modeling process is divided in a typical sequence of activities, i.e., requirements specification, analysis, and design. ...
ROLES IN OBJECT-ORIENTED AND AGENT-ORIENTED MODELING We will first give a general definition of the notion of a role in object-oriented modeling and then we explain which properties a concept of roles ...
