Schema Refinement and Schema Integration in Object-oriented Databases Schema Reenement and Schema Integration in Object-oriented Databases

چکیده
This report presents a formal approach to support schema integration in object-oriented databases. The basis of the approach is a synthetic subclass order to compare classes. Classes are integrated in a natural way using a join operator w.r.t. the subclass order. In contrast with existing literature, our subclass order compares classes not only by their attributes, but also by the behaviour of their methods, leading to a more semantic approach towards schema integration in object-oriented databases.

Object Oriented Approach for Integration of Heterogeneous Databases in a Multidatabase System and Local Schemas Modifications Propagation
One of the challenging problems in the multidatabase systems is to find the most viable solution to the problem of interoperability of distributed heterogeneous autonomous local component databases. This has resulted in the creation of a global schema over set of these local component database schemas to provide a uniform representation of local schemas. The aim of this paper is to use object-o...
متن کاملDetermining Schema Interdependencies in Object-Oriented Multidatabase Systems
Schema analysis is the process of determining and capturing how individual schema items in diverse databases are related to each other. During this process different types of semantic relationships between schema items in different databases are identified and meaningful cross-links are established. The work presented in this paper concentrates on the issue of determining several types of inter...
متن کاملSchema Integration between Object-Oriented Databases
There are two key motivations for this work. First, the implementation of object-oriented databases has grown to a significant number. Second, there has been a need for integrated access of information from multiple data sources. The multidatabase system has been proposed as a solution for integrated access of data from multiple distributed, heterogeneous, and autonomous database systems. To pr...

This report presents a formal approach to support schema integration in object-oriented databases. The basis of the approach is a synthetic subclass order, which is deened in terms of a weak subtype relation on underlying types of classes and a subfunc-tion relation on functional forms of methods. Classes are identiied using an equivalence relation induced by the subclass order and factorised u...
متن کاملTemporal Object-Oriented Data Model for the Schema Modification
A temporal database management system is being considered as an important DBMS in new database applications such as engineering databases, VLSI, and CAD. Much researche on temporal databases, temporal query languages and temporal modeling techniques have been proposed. However, thus researche has not considered the schema modification problem in a temporal database yet. In this paper, we propos...
