چکیده
* This work is partially supported by the grants No. 8T11C04315 from the State Committee for Scientific Research (KBN), Poland Abstract In this paper we discuss an approach to object– oriented views that we have developed, and propose its implementation. In our model an object–oriented view is defined as a view schema of an arbitrary complex structure and behaviour, composed of view classes. Each view class is derived from one or more source classes by an OQL–like command, defining its structure, behaviour and the set of instances. In our implementation we use a three–layer architecture with metaclasses, classes, and objects.

Flexible Object-Oriented Views Using Method Propagation
Object-oriented views play a key role when giving accessing applications a new or restricted perspective on persistent object-oriented data. However, traditional object-oriented view systems only allow for limited changes when it comes to restructuring a database schema and the related persistent objects in a view. We present a new approach for defining object-oriented views that enables view s...
متن کاملObjects Identification in Object-Oriented Software Development - A Taxonomy and Survey on Techniques
Analysis and design of object oriented is onemodern paradigms for developing a system. In this paradigm, there are several objects and each object plays some specific roles. Identifying objects (and classes) is one of the most important steps in the object-oriented paradigm. This paper makes a literature review over techniques to identify objects and then presents six taxonomies for them. The f...

View mechanisms, widely used in the relational databases, pose new questions in the object model which captures much more semantics. In this paper, we will focus on inheritance and inter-objects relationships, two main semantic aspects of the object model. Like in the relational model, most of the current works about object-oriented views assume a fine granularity of the views. View classes are...
متن کاملSchema Integration for Object Oriented Database Systems
View integration is an important technique for developing software systems built upon large databases independent which paradigm is used for realizing the database. We analyzed to which extent traditional view integration methods cover all aspects of object-oriented datamodels and found, in particular, that the integration of methods is hardly supported. We present a methodology for integrating...
متن کاملClinical Views: Object-Oriented Views for Clinical Databases
We present here a prototype ofa clinical information system for the archiving and the management of multimedia and temporally-oriented clinical data related to PTCA patients. The system is based on an object-oriented DBMS and supports multiple views and view schemas on patients' data. Remote data access is supported too.
