Implementation Patterns of Object Static Models for Database Applications: Classical ORM-Patterns and Object-Attribute Approach

摘要

This article presents two different approaches to the representation of static models in the implementation of database applications. In order to compare solutions based on selected criteria of optimality the unified model for testing of tools development of object-oriented applications presented in the form of a class diagram language UML is created. As one of the implementations the classical object-relational mapping patterns proposing static models in the environment of a relational DBMS is concerned. An alternative solution widely used by one of the authors is the object-attributive approach. The paper presents the main components of this approach and example of the unified testing model. This paper is the result of years of research and is based on numerous articles published in the Proceedings of the International Scientific and Practical Conference "Object Systems" (objectsystems.ru).
