A Declarative Query Approach to Object Identification

نویسنده

Martin Gogolla

چکیده

Object identiication in data models, especially in semantic, Entity-Relationship, and Object-Oriented data models is studied. Various known approaches to object identiication are shown, and an alternative proposal to the topic is put forward. The main new idea is to attach to each object type an arbitrary query in order to observe a unique, identifying property of objects of the corresponding type.

One of the modern paradigms to develop an application is object oriented analysis and design. In this paradigm, there are several objects and each object plays some specific roles in applications. In an application, we must distinguish between procedural semantics and declarative semantics for their implementation in a specific programming language. For the procedural semantics, we can write a ...

One major approach to realise database integration is to adapt and merge the database schemas by defining views. When integrating object-oriented databases, the views need to adequately support object identity and methods. View objects need to be identified on the basis of the objects they have been derived from. Methods must be callable from the query processor without impeding query optimisat...

A Deductive Declarative Object-Oriented Data Model and Query Language based on Narrowing

The pure object-oriented data model is not convenient for describing inter-object relationships and can result in very involved and hard to understand queries. Augmenting the objectoriented model with declarative description of the relationships between objects using conditional rewrite rules is a convenient way to address the problem. Under this scheme, inter-object relationships are described...
