The notion of context appears in computer science, as well as in several other disciplines, in various forms. In this paper, we present a general framework for representing the notion of context in information modeling. First, we define a context as a set of objects, within which each object has a set of names and possibly a reference: the reference of the(More)
The distribution of lidocaine and digoxin in myocardial and aorta tissues of open chest anesthetized dogs was studied, following the administration of 30 ml phosphate buffer solution of the drugs in the pericardial cavity where it was kept for increasing time intervals. Transfer of lidocaine (15 or 30 mg) from the solution to myocardium was almost complete(More)
Although semantic data models provide expressive conceptual modeling mechanisms, they do not support context, i.e. providing controlled partial information on conceptual entities by viewing them from different viewpoints or in different situations. In this paper, we present a model for representing contexts in information bases along with a set of(More)

In information bases following semantic and object oriented data models logical names are used for the external identi cation of objects Yet the naming schemes em ployed are not natural enough and several problems often arise logical names can be ambiguous excessively long unrelated to or unable to follow the changes of the environment of the named object(More)
The notion of context appears in several disciplines, including computer science, under various forms. In this paper, we are concerned with a notion of context in the area of conceptual modeling. First, we present a simple definition whereby a context is seen as a set of objects, within which each object has a set of names and possibly a reference: the(More)
We propose developing hypermedia applications over an information repository. The main benefits of this approach include development efficiency, product quality, ease of tailoring and extensibility. In particular we focus on design and implementation issues related to presenting, navigating and retrieving large amounts of highly interlinked, complex data.(More)
