This book was released on 1989 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: DE NOMBREUX DOMAINES D'APPLICATIONS TELS QUE: LA CONCEPTION ASSISTEE PAR ORDINATEUR (CAO), LA PRODUCTION DE DOCUMENTS INCORPORANT TEXTES, IMAGES ET GRAPHIQUES, LE GENIE LOGICIEL, NECESSITENT UNE REPRESENTATION DIRECTE D'OBJETS COMPLEXES AINSI QUE LEUR MANIPULATION EFFICACE. L'APPROCHE ORIENTE-OBJET OFFRE DE NOMBREUX AVANTAGES POUR MODELISER TANT CES DOMAINES D'APPLICATION QUE LES TRAITEMENTS QUI LEUR SONT ASSOCIES. A L'AVENIR, LES SYSTEMES DE GESTION D'OBJETS DEVRONT FOURNIR LES FONCTIONNALITES NECESSAIRES POUR SUPPORTER DES MODELES DE DONNEES COMPLEXES. UNE DES CONTRAINTES ESSENTIELLE A RESPECTER EST L'INDEPENDANCE DES OBJETS. IL FAUT DONC METTRE EN UVRE DES TECHNIQUES DE STOCKAGE PERMETTANT DE REPARTIR LES OBJETS SUR DES SUPPORTS PHYSIQUES TOUT EN TENANT COMPTE DES LIENS LOGIQUES QUI LES RELIENT. DANS CE CADRE, DE BONNES STRATEGIES DE REGROUPEMENT S'AVERENT ETRE CRUCIALES AFIN D'AUGMENTER LES PERFORMANCES DE CES SYSTEMES. DANS CETTE THESE, NOUS DEFINISSONS DES STRATEGIES DE REGROUPEMENT ET PRESENTONS UN ALGORITHME DE REGROUPEMENT D'OBJETS SUR DISQUE. NOUS DEVELOPPONS, ENSUITE, UN MODELE DE COUT DESTINE A EVALUER LA QUALITE DE CHAQUE STRATEGIE. CE MODELE DE COUT NOUS PERMETTANT ALORS DE DERIVER AUTOMATIQUEMENT, EN UN TEMPS LINEAIRE, DE NOUVELLES STRATEGIES DE REGROUPEMENT. UN ENSEMBLE DE MESURES A ETE DEVELOPPE, CES MESURES NOUS PERMETTANT DE VALIDER LA PORTEE DU MODELE DECRIT

Download or read book ICDT '90 written by Serge Abiteboul and published by Springer Science & Business Media. This book was released on 1990-12-03 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emergence of new paradigms for data management raises a variety of exciting challenges. An important goal of database theory is to answer these challenges by providing sound foundations for the development of the field. This volume contains the papers selected for the third International Conference on Database Theory, ICDT'90. The conferences in this series are held biannually in beautiful European cities, Rome in 1986 and Bruges in 1988 with proceedings published as volumes 234 and 326 in the same series. ICDT'90 was organized in Paris by the Institut National de Recherche en Informatique et Automatique. The conference features 2 invited presentations and 31 papers selected from 129 submissions. The papers describe original ideas and new results on the foundations of databases, knowledge bases, object-oriented databases, relational theory, transaction management, data structures and deductive databases. The volume offers a good overview of the state of the art and the current trends in database theory. It should be a valuable source of information for researchers interested in the field.

Available in PDF, EPUB and Kindle. Book excerpt: CE TRAVAIL S'INSCRIT DANS LE DOMAINE DE L'OPTIMISATION DES PERFORMANCES DES SGBD ORIENTES OBJET. L'IDEE MAJEURE MISE EN UVRE CONSISTE A TIRER PROFIT DE L'UTILISATION EFFECTIVE DES LIENS INTER-OBJETS POUR GERER UNE POLITIQUE DYNAMIQUE DE REGROUPEMENT D'OBJETS SUR DISQUE, COUPLEE A UNE POLITIQUE DE GESTION DE CACHE MEMOIRE ORIENTEE GROUPEMENT. UNE ETUDE APPROFONDIE DU DOMAINE PERMET DE DETERMINER, A L'AIDE D'UNE METHODOLOGIE D'EVALUATION, LES INSUFFISANCES MAJEURES ATTRIBUABLES AUX STRATEGIES DE REGROUPEMENT EXISTANTES ET ILLUSTRE EGALEMENT LA NECESSITE D'UNE GESTION DE CACHE MEMOIRE MIEUX ADAPTEE A L'UTILISATION EFFECTIVE DES OBJETS. LA STRATEGIE PROPOSEE, DENOMMEE STD, EST BASEE SUR UN PROCESSUS D'ANALYSE DU COMPORTEMENT DU SGBD, QUI EST PARAMETRABLE, AUTO-ADAPTATIF ET GENERIQUE. UNE DEMARCHE DE VALIDATION DE LA SOLUTION EST CONDUITE AU TRAVERS D'UNE IMPLEMENTATION AU SEIN DU SYSTEME DE STOCKAGE PERSISTANT TEXAS.

Download or read book Des objets complexes aux bases de données orienté-objet written by Philippe Richard and published by . This book was released on 1989 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is concerned with the two main streams of database research: • Complex object models: the relational data model provides a good theoretical foundation for databases and data manipulation languages. However, this model lacks of semantic power for the new emerging applications of databases (CAD, CAM, Office automation). The data involved in these domains of application are structurally more complex than sets of flat tuples. Our work in the Verso project defines a model for complex objects whose operations can be implemented by a finite state automaton which filters data on the fly. • Object-oriented databases: although complex objects models provide good solutions for taking into account complex data, they fall short of solving the problem of applications programming. Their associated languages lack of the necessary computing power. In the early 80's, new systems appeared which mixed database functionalities with the computing power of a general purpose programming language. Depending of the approach, we can speak of persistent programming languages or object oriented data bases.This work is composed of two parts. The first one (Chapters I to V) presents a state of the art which describes the main results in the database research on complex objects models (chapter I) and database pro gramming languages ( chapters II to V). The second part of this thesis (Chapter VI) groups seven publications which describe our work in these two domains.

Available in PDF, EPUB and Kindle. Book excerpt: LES BASES DE DONNEES CONSTITUENT LE SUPPORT INCONTOURNABLE DE NOMBREUX SYSTEMES D'INFORMATION. LA COMPLEXITE DES APPLICATIONS DE BASES DE DONNEES NECESSITE DES MECANISMES PUISSANTS POUR CONTROLER L'INTEGRITE DES DONNEES. CES MECANISMES UTILISENT GENERALEMENT UN ENSEMBLE D'ASSERTIONS APPELEES CONTRAINTES D'INTEGRITE. ELLES CORRESPONDENT A DES PROPRIETES QUI DEVRONT TOUJOURS ETRE VERIFIEES DANS LA BASE DE DONNEES. CES CONTRAINTES ONT POUR BUT DE GARANTIR LA SEMANTIQUE DES INFORMATIONS STOCKEES DANS LA BASE, C'EST-A-DIRE DE LES PROTEGER CONTRE DES MANIPULATIONS ERRONEES. LE BUT DE CETTE THESE EST DE PROPOSER UN SYSTEME DE GESTION DE CONTRAINTES D'INTEGRITE (SGC) DANS UN ENVIRONNEMENT ORIENTE OBJET. A L'HEURE ACTUELLE, AUCUN SYSTEME DE GESTION DE BASE DE DONNEES ORIENTES OBJET (SGBDOO) NE TIENT COMPTE DE L'ASPECT COMPORTEMENTAL DES OBJETS DANS LA DEFINITION DE CONTRAINTES D'INTEGRITE. NOTRE CONTRIBUTION SERA D'APPORTER UN ENSEMBLE DE SOLUTIONS PERMETTANT DE GERER CE TYPE DE CONTRAINTES ET PLUS GENERALEMENT DE PROPOSER UN SYSTEME DE GESTION DE CONTRAINTE DANS UN ENVIRONNEMENT ORIENTE OBJET. CE SYSTEME OFFRE TOUTES LES FONCTIONNALITES NECESSAIRES A LA GESTION DE CONTRAINTE. IL PERMET, LA DEFINITION DE CONTRAINTES EXPRIMEES DE MANIERE GLOBALE ET DECLARATIVE DE VERIFIER QUE L'ENSEMBLE DES CONTRAINTES N'EST PAS CONTRADICTOIRE, D'ASSURER DE MANIERE EFFICACE LE RESPECT DES CONTRAINTES LORS DES MISES A JOUR DES DONNEES DE LA BASE ET DE RETABLIR L'INTEGRITE LORSQUE CETTE DERNIERE EST MISE EN DEFAUT. LES SOLUTIONS PROPOSEES METTENT EN JEU DES MECANISMES COMPLEXE ET PRENNENT EN COMPTE DE L'ENSEMBLE DES PARTICULARITES DES MODELES ORIENTES OBJET TELLES QUE L'HERITAGE, LE SOUS-TYPAGE, LES METHODES, LA RESOLUTION TARDIVE AINSI QUE LES LIENS AVEC LA PERSISTANCE
