Object-Oriented Translation for Programmable Relational System (DRAFT)

TL;DR

This paper presents an object-oriented translation approach for a programmable relational system, enabling complex object manipulation and operations within a relational framework, enhancing data modeling and query capabilities.

Contribution

It introduces a method to convert object-oriented data structures and operations into relational descriptions, allowing object views and polymorphic methods in a relational context.

Findings

Supports complex object data as relational structures

Enables execution of object operations without explicit iterators

Integrates classes with relations for enhanced data modeling

Abstract

The paper introduces the principles of object-oriented translation for target machine which provides executing the sequences of elementary operations on persistent data presented as a set of relations (programmable relational system). The language of this target machine bases on formal operations of relational data model. An approach is given to convert both the description of complex object-oriented data structures and operations on these data, into a description of relational structures and operations on them. The proposed approach makes possible to extend the target relational language with commands allowing data be described as a set of complex persistent objects of different classes. Object views are introduced which allow relational operations be applied to the data of complex objects. It is shown that any operation and method can be executed on any group of the objects without explicit and implicit iterators. Binding of both attributes and methods with their polymorphic implementations are discussed. Classes can be co-used with relations as scalar domains, in referential integrity constraints and in data query operations.
