OOPS-an object oriented programming system with integrated data management facility

Abstract

A b s t r a c t For various reasons conventional database systems f a i l t o provide appropriate support f o r a wide v a r i e t y of applications. Therefore, new generation database systems are being developed i n some recent research efforts, among them OOPS. OOPS is an object-oriented programming environ-ment with integrated d a t a management facilities. I t is designed t o especially support advanced applications, l i k e e. g. engineering and o f f i c e applications.Rich d a t a modelling f a c i l i t i e s , including t h e concepts of classif ication, generalization and aggregation, are provided. Additionally, complex semantic i n t e g r i t y constraints, exception-handling mechanisms and t r i g g e r s can be specified. Since all these facilities are integrated i n t o a single language, t h e a r t i f i c i a l d i s t i n c t i o n between database language and programming language is no longer existent. In t h i s paper w e w i l l essentially present t h e main f e a t u r e s of t h e programming language and t h e a r c h i t e c t u r e of OOPS. Due t o space limitations a discussion of t h e database component is skipped.

Engineering the object-relation database model in O-raid

“…While the relational model is simple, it has several limitations that are well documented in the database literature (recently in [4, 24,26] and [29]). These limilations include lack of support for:…”

“…Several solutions have been proposed to overcome these limitations. These include lhe logical relational design methodology [32], alerters, triggers, and constraints [5,6,24] and tile object-oriented data model [11,15,18,26].…”
