An Efficient Design and Implementation of a Heterogeneous Deductive Object-Oriented Database System

چکیده
Object-oriented database system supports the powerful concepts of data abstraction and complex data modeling while deductive database system has inferential and declarative query capabilities. Previous research has demonstrated the advantages and feasibilities of the confluence of the declarative logic-based paradigm and the object-oriented paradigm in the dual-paradigm system of deductive object-oriented database systems. However, the previous research either concentrated on the homogeneous architecture of a complete logical system or the heterogeneous architecture with the schema rules carried over to the deductive database. Our research proposes the use of heterogeneous architecture that minimizes communications between an object-oriented database system and a deductive system. In this paper, we outline the architecture and the system of deductive rules. We demonstrate the efficiency in query processing by separating the schema rules of object orientation from the deductive rules. We also address the object-oriented relationships in this dual-paradigm database system.

Design and implementation of ROCK & ROLL: a deductive object-oriented database system
This paper presents an approach to the development of a deductive object-oriented database system, describing the key design decisions and their consequences for implementation. The approach is novel, in that it integrates an object-oriented database system manipulated using an imperative programming language (ROCK) with a logic language for expressing queries and methods (ROLL). The integratio...
متن کاملDeclarative Semantics in Object-Oriented Software Development - A Taxonomy and Survey
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 ...
