RDBM vs OODBM in support of integrated data bases for computer aided building design

Abstract: Computer technology has changed the way architects and engineersdesign, analyze, plan, estimate and document buildings. In the last few years powerful and affordable software and supporting hardware havereplaced traditional tools, making modeling, engineering calculationsand drawing quicker and easier. Software designers and researchers are constantly forecasting an even brighter future, with cheaper and better computer applications available to the practicing architect. This trend will continue; but the promises made in the 60' s and 70's, of athinking, computer design assistant, or of a completely integrated collection of architectural design, analysis and drawing tools, may takelonger than first forecast. A critical issue which must be investigated for the "next generation" of computer aided building design applications is integrated building data bases. These data bases must be dynamic and extendable to support new types of information; must be shareable by architectural designers and various types of engineers; must beable to support collaborated design activities; must be able to effectively represent complex relationships among design objects; and must provide enough power for rich data modeling. The benefits of an integrated system have been recognized and reported as an important issue for many years. Conventional data base management systems (e. g., network, hierarchical, or relational) may not be adequate to support these requirements, but advancements in data base technology make it possibleto now address the problem. This paper will compare two data base management technologies - the relational data base and the object-oriented data base - as candidates to support an integrated architectural CADenvironment. In order to investigate these two approaches, a simple architectural design scenario and conceptual building model are presented. The relational and object- based approach will be implemented fromthe scenario and model. The paper will co
