On PROGRESS Operation. How to Make Object-Oriented Programming System More Object-Oriented (DRAFT)

TL;DR

This paper introduces the PROGRESS operation, a novel method to modify objects within inheritance hierarchies, addressing limitations in traditional object-oriented systems for persistent objects.

Contribution

It proposes an alternative realization of object modification that overcomes fundamental drawbacks of traditional OO implementations in persistent systems.

Findings

The PROGRESS operation enables flexible object modifications.

It simplifies implementation of persistent modifiable objects.

The approach improves object-oriented system flexibility.

Abstract

A system, which implements persistent objects, has to provide different opportunities to change the objects in arbitrary ways during their existence. A traditional realization of OO paradigm in modern programming systems has fundamental drawbacks which complicate an implementation of persistent modifiable objects considerably. There is alternative realization that does not have these drawbacks. In the article the PROGRESS operation is offered, which modify existing object within an existing inheritance hierarchy.
