Updating Views in Object Oriented Database Systems
A variety of view definitions have been defined for object oriented database systems. In this paper we study the problem of what happens to a view when the underlying schema and database are updated. We introduce the new concept of non-side effect view. A non-side effect view is a view which is re-computed dynamically so that schema modifications are (whenever possible) "filtered out" from appl...
متن کاملOn a Formal Model of an Object-Oriented Database with Views Supporting Data Materialisation
In this paper we propose a model of an object–oriented database with views. A view in our approach can have arbitrary complex structure. The crucial point of our model is that a view schema is totally separated from the original database schema. By this separation we achieved two following goals: logical data independence provided by a view schema and strong mechanism for data hiding and securi...
متن کاملA Formal Model of Concurrency for Distributed Object-Oriented Systems
It is widely accepted that object-oriented constructions can be used as a pertinent basis for the support of distributed systems consisting of concurrently executing objects that communicate and interoperate among them. In this context, distributed object systems are representedfrom a process-oriented perspective which uses the process as the basic modelling structure. This point of view allows...

متن کاملA multilevel security model for object-oriented database systems
ing superclasses Objects in an object-oriented database have various relationships which have been discussed. If the designer is aware of these relationships during the design phase, many of these relationships can be exploited. For example, STUDENT is related to PERSON in that all students are people, so the commonalities between the two are extracted and placed in the class PERSON. The subcla...
