The aim of the research described in this paper is to evaluate the quality of different conceptual model versions of the same universe of discourse by different Information Systems (IS) stakeholders. This paper describes: a) a set of quality factors (clarity, simplicity, expressiveness, minimality) applied to different versions of ER conceptual schemas, b) an approach enabling a comprehensive comparison of the conceptual schemas, c) an experimentation leading to the evaluation of the same schemas by IS stakeholders such as designers, end-users, and students, based on a sample of about 120 observations using different statistical methods. First results indicate that there exists a strong independence between the IS stakeholders and the quality factors used. A second result reveals a significant difference between groups of respondents in their ways to perceive conceptual schemas quality. Based on our experiment, we are able to identify quality factors relevant to different groups of stakeholders, depending on several dimensions, such as their professional experience, and/or their specialization degree."

"fr" => "L'objet de cet article est la présentation d'un modèle de comportement d'un utilisateur sur un réseau d'ordinateurs. Ce modèle est utilisé pour la détection avancée de malveillances sur un réseau. Le système, appelé DAMaR (Détection Avancée de Malveillances sur un Réseau), étudie le comportement ou profil habituel de l'utilisateur défini notamment par des composantes quantitatives (temps CPU, nombre moyen d'erreurs de connexion, nombre moyen d'utilisations des primitives du système et des logiciels, nombre d'accès en lecture/écriture à chaque base de données, etc.) et des composantes qualitatives (jour et heure habituels de connexion, poste de travail, etc.). Un changement de comportement peut dans certains cas traduire une intention de malveillance. Dès qu'un profil subit des modifications sensibles, une enquête est déclenchée. Ce profil n'est pas déterminé a priori, mais il se crée à l'issue d'une période d'apprentissage et d'observation des utilisateurs. Pour éviter de saturer le réseau, les utilisateurs sont répartis dans différentes classes de risque. Au départ, tous les individus sont dans la même classe. Au fur et à mesure des variations de leur comportement, les individus changent de classe. Le passage d'une classe à l'autre se fait soit de façon automatique soit par l'administrateur sur la suggestion de l'automate. Ce système, fonctionnant suivant un mode centralisé, a été expérimenté avec succès sur un réseau UNIX.

This system, called DAMaR (a French acronym for Advanced Dectection of Malevolences in a Computer Network), analyzes users behavior characterized by quantitative components such as CPU time, average number of erroneous connections, average number of system and software primitives usage, etc. and qualitative components such as day and time of regular connections, workstation number, etc. Any change in the behavior may be interpreted as a malevolent intention. Whenever user profile changes in a significant manner, an enquiry is triggered. The profile is not predefined but initialized during a learning period where the system observes users. To avoid network saturation, users are assigned to risk classes. At the beginning, all the users are located in the same class. Users behavior variations induce class changes. The system has been implemented on a UNIX network on a centralized mode. It allowed us to illustrate the dynamics of the model by exhibiting user class changes."

"en" => "Data warehouses are a major component of data-driven decision support systems (DSS). They rely on multidimensional models. The latter provide decision makers with a business-oriented view to data, thereby easing data navigation and analysis via On-Line Analytical Processing (OLAP) tools. They also determine how the data are stored in the data warehouse for subsequent use, not only by OLAP tools, but also by other decision support tools (e.g. reporting or data mining). Data warehouse design is a complex task, which requires a systematic method. Few such methods have been proposed to date. This paper presents a UML-based data warehouse design method that spans the three design phases (conceptual, logical and physical). Starting from user requirements, the conceptual phase leads to an object-oriented model represented using the UML notation. For this purpose, UML is enriched with concepts relevant to multidimensional modeling. The logical phase maps the enriched UML model into a multidimensional schema, independently of any implementation tool. The physical phase allows the designer to map the multidimensional schema into a physical database schema depending on the implementation target tool, typically a native multidimensional (MOLAP) or a relational (ROLAP) tool. Our method comprises a set of metamodels used at each phase (in particular a unified multidimensional metamodel used at the logical phase), as well as a set of transformations that can be semi-automated. Following our object orientation, we represent all the metamodels using UML, and illustrate the formal specification of the transformations based on OMG¿s Object Constraint Language (OCL). Throughout the paper, we illustrate the application of our method to a case study."

"fr" => "La qualité de l’information est une notion complexe et multidimensionnelle. Dans le contexte de l’ingénierie des systèmes d’information, c’est aussi une notion transversale dont la compréhension nécessite l’évaluation conjointe de la qualité des données, de la qualité du modèle conceptuel sous-jacent et de la qualité du logiciel qui gère ces données. Cet article présente un modèle multidimensionnel permettant l’exploration de l’information d’une façon multidimensionnelle, avec une aide à la navigation, au filtrage et à l’interprétation des mesures de qualité. Ainsi, des actions appropriées d’amélioration de la qualité de l’information peuvent être identifiées. Deux scenarii d’applications sont décrits permettant une validation de l’approche : le premier traite de la qualité de l’information relative aux clients, chez EDF. Le second évalue la qualité des dossiers patients à l’Institut Curie. L’instantiation du modèle multidimensionnel dans ces deux contextes est une illustration de l’applicabilité de l’approche."
"en" => "Information quality is a complex and multidimensional notion. In the context of information system engineering, it is also a transversal notion and to be fully understood, it needs to be evaluated jointly considering the quality of data, the quality of the underlying conceptual data model and the quality of the software system that manages these data. This paper presents a multidimensional model for exploring information in a multidimensional way, which aids in the navigation, filtering, and interpretation of quality measures, and thus in the identification of the most appropriate actions to improve information quality. Two application scenarios are presented to illustrate and validate the multidimensional approach: the first one concerns the quality of customer information at Electricité de France, a French Electricity Company, and the second concerns the quality of patient records at Curie Institute, a well-known medical institute in France. The instantiation of our multidimensional model in these contexts shows first illustrations of its applicability."

"fr" => "La « Business Intelligence » (BI) a connu ces dernières années une croissance importante, tant en ce qui concerne les produits disponibles sur le marché que le nombre d’entreprises qui l’ont adoptée. De même les chercheurs se sont attaqués aux problématiques techniques et organisationnelles soulevées par ce domaine très dynamique de l’informatique. Le terme de « Business Analytics » couvre un périmètre partiellement commun. Cet article propose une définition de la Business Intelligence résultant d’un effort de synthèse des différentes visions de ce concept. Puis, nous construisons une taxonomie de la Business Intelligence. Cette taxonomie nous sert à organiser ensuite l’état de l’art qui recense les approches de recherche en matière de BI. Cet état de l’art permet au lecteur d’appréhender les composants de la BI et les spécificités des recherches dans ce domaine. En montrant les efforts effectués, il permet aussi de déduire les problèmes encore ouverts."
"en" => "Business intelligence (BI) is a very dynamic field. During last years, many products appeared and numerous companies have decided to adopt BI techniques and tools. It is also a hot topic for researchers either in computer science or in information systems. Business Analytics is often used as a synonym of BI. This paper proposes a definition of business intelligence as a consensus of most definitions found in the literature. Then, we build a taxonomy of BI. This taxonomy allowed us to structure the state-of-the-art in BI which is the main contribution of this paper. It allows readers to understand all the components of BI and the research contributions associated to each component. It also allows researchers to detect open issues."

Nous décrivons un cadre d'évaluation de la qualité des schémas conceptuels. Sur la base de critères de qualité décrits dans la littérature, nous définissons des métriques d'évaluation de ces schémas. Nous avons testé ces métriques sur des exemples alternatifs de schémas conceptuels décrivant la même situation. Les leçons à tirer de cette expérimentation sont décrites dans l'article."
"en" => "This paper presents exploratory research that investigates an evaluation process of conceptuel specifications. We primarily address the problem of assessing conceptual modeling quality. In particular, we provide a comprehensive framework for evaluating conceptual schemas. Based on quality criteria proposed in the literature, we select the subset of criteria relevant to conceptual schema quality evaluation. For each criterion, we define one or several metrics allowing the designer to measure schemas quality. In order to validate our approach, we evaluated several alternative UML conceptual schemas representing the same universe of discourse. The results and lessons learned from this evaluation are detailed."

"en" => "Ensuring and maximizing the quality and integrity of information is a crucial process for today enterprise information systems. It requires a clear understanding of the interdependencies between the dimensions characterizing quality of data (QoD), quality of conceptual data model (QoM) of the database, keystone of the EIS, and quality of data management and integration processes (QoP). The improvement of one quality dimension (such as data accuracy or model expressiveness) may have negative consequences on other quality dimensions (e.g., freshness or completeness of data). In this paper we briefly present a framework, called QUADRIS, relevant for adopting a quality improvement strategy on one or many dimensions of QoD or QoM with considering the collateral effects on the other interdependent quality dimensions. We also present the scenarios of our ongoing validations on a CRM EIS."

Une majorité des demandes de changements des systèmes d'information (SI) résultent de fonctionnalités défectueuses de ces SI. C'est pourquoi une bonne méthode d'analyse et de conception devrait garantir que les modèles conceptuels sont corrects, complets et faciles à comprendre, puisqu'ils sont le moyen de communication entre les utilisateurs et l'équipe de développement. De même, si les modèles sont complexes, leur extension ou l'incorporation d'exigences manquantes est très difficile pour les concepteurs. Notre approche évalue les modèles conceptuels à différents niveaux de granularité et propose des actions correctives ou des transformations en vue de leur amélioration. Nous proposons des patrons de qualité pour aider les utilisateurs non-experts à évaluer leur modèle en fonction de leur objectif. Cet article illustre aussi l'approche en décrivant le processus d'évaluation et d'amélioration sur une étude de cas."
"en" => "Conceptual models are of prime importance to ensure a high level of quality in designing information systems. It has been witnessed that the majority of information systems (IS) change requests result due to deficient functionalities in the information systems. Therefore, a good analysis and design method should guarantee that conceptual models are correct and complete and easy to understand, as they are the communicating mediator between the users and the development team. Similarly, if models are complex then their extension or the incorporation of missing requirements gets very difficult for the designers. Our approach evaluates the conceptual models on multiple levels of granularity in addition to providing the corrective actions or transformations for improvement. We propose quality patterns to help the non-expert users in evaluating their models with respect to their quality goal. This paper also illustrates our approach by describing an evaluation and improvement process using a case study."

An important and understudied challenge is how to translate DSR project research goals into discrete and measurable evaluation criteria for use in the DSR processes. This position paper proposes an inclusive approach for articulating DSR goals and then identifying project evaluation criteria for these goals. The goals are organized hierarchically as utilitarian goals, safety goals, interaction and communication goals, cognitive and aesthetic goals, innovation goals, and evolution goals. Goals in a DSR project are identified pragmatically by considering the components of the context coupled with the hierarchy of goals. Based on the identified goals, the associated evaluation criteria are determined and organized along the same hierarchy. These criteria measure the ability of the artifact to meet its goals in its context (immediate fitness). Moreover, our approach also supports the innovation and research contributions of the project. The apex of the goal hierarchy addresses the identification of criteria measuring the fitness for evolution of the designed artifact, to accommodate for changes in goals or context."

"fr" => "Cet article décrit une approche combinée de deux techniques utilisées en conception de bases de données : l'intégration de vues et la classification de schémas. Les méthodes d'intégration de vues usuelles traitent principalement les problèmes de terminologie, de recouvrement de classes, de contradictions de contraintes et d'équivalences de représentations. Cependant deux autres types de problèmes restent sans solution. Le premier est la comparaison deux à deux des concepts des deux vues qui peut conduire à un processus très coûteux mettant en place la confrontation exhaustive de tous ces concepts : n2 comparaisons pour des vues comprenant chacune n concepts. Nous proposons une technique de classification automatique, qui permet de réduire le nombre de comparaisons élémentaires à n2/4 dans le pire des cas et à n dans le cas le plus favorable. Le second problème est la validation de l'intégration. En effet, le processus d'intégration conduit à un schéma global amalgamant toutes les vues initiales. La validation consiste à vérifier que ce schéma contient effectivement chacune des vues initiales. Là encore, nous proposons d'appliquer la même technique de classification avec des distances sémantiques spécifiques. Les deux utilisations de la classification automatique ont fait l'objet du développement d'un prototype qui a permis de tester la technique sur plusieurs exemples de vues de grande taille."
"en" => "The aim of this paper is to provide a coherent combination of two well-known techniques improving database design : view integration and schema clustering. View integration methods suggested in the literature tend to address mainly the following problems: terminology problems, class definition overlappings, constraint contradictions, different representations of concepts. However two other problems remain unsolved. The first one is concerned with view comparison, which may lead to a very costly process requiring, for two views containing about n objects, up to n2 elementary comparisons. This paper proposes a clustering technique for solving this problem. The clustering is based on an automatic process, reducing the number of elementary comparisons to n2/4 in the worst case and n in the best case. The second problem is related to view integration validation. The view integration process leads to a global schema amalgamating all the initial views. View integration validation consists mainly in checking that this objective is met. This paper proposes an application of automatic clustering to view integration permitting to recover the initial views. In order to validate view integration, the clustering algorithm requires the application of several semantic distances taking into account different integration situations. We propose to perform the clustering process using successively several distances until a satisfying partitioning is obtained. The two techniques have been applied to several case studies leading to empirical but very promising results."

Le second DREAM emprunte largement à l'approche orientée objet. En utilisant un ensemble de critères et de métriques de comparaison des modèles conceptuels, fondés sur le point de vue du concepteur, nous montrons que le modèle DREAM offre plus d'expressivité au prix d'une diminution relative de la simplicité."

The main results of our comparison show that the expressiveness of the DREAM model is higher than that of the REA diagrams."

L'étape d'intégration de vues par unification sémantique est suivie par la confrontation des contraintes d'intégrité initiales. La phase de détection est un processus déductif dans lequel les contradictions et redondances entre les contraintes sont exhibées. La résolution des conflits dépend ensuite de la stratégie choisie par le concepteur. Quatre stratégies sont proposées et discutées. Un exemple d'utilisation est donné pour chacune. Cette approche pourrait être étendue au contexte orienté objet où à la fois contraintes et méthodes sont à comparer."
"en" => "This paper addresses the problem of constraint integration in database design. The approach is inserted in an incremental database design methodology supported by the design environment KHEOPS. This view integration step using semantic unification is followed by the initial constraint confrontation. The detection phase is a deductive process in which the contradictions and redundancies between constraints are exhibited. The following conflict resolution depends on the strategy initially chosen by the designer. Four strategies are presented and discussed. An exemple of use is given to illustrate the application of those strategies. This approach could be enlarged in an object oriented context where schemata would have not only constraints but also methods to compare."

It then proposes a comprehensive model for evaluating the quality of conceptual models. A survey involving practitioners has been used as an initial validation.

This article addresses the conceptual model quality as it has been widely accepted that better conceptual models produce better information systems and thus implicitly improve the data quality. Conceptual Models are designed as part of the analysis phase and serve as a communicating mediator between the users and the development team. Consequently, their understandability is a real challenge to avoid the propagation of inaccurate interpretation of the user requirements to the underlying system design and implementation. In this paper, we propose an adaptive quality model. We illustrate its usefulness by describing how it can be used to model and evaluate the understandability of conceptual models. Our quality evaluation is enriched with corrective actions provided to the designer, leading to a guidance modeling process. A first validation based on a survey is proposed."

Kimball fondée sur le modèle en flocon , - la méthode MAP, de J. Akoka et N. Prat, fondée sur le modèle multidimensionnel. Un même exemple complet de système décisionnel d'évaluation des entreprises en vue d'un rachat est traité dans les trois approches. La méthode MAP a l'avantage de distinguer les phases de modélisation conceptuelle et logique, facilitant le processus. Les méthodes de R. Kimball ont l'intérêt de permettre une mise en œuvre rapide, notamment avec certains outils. Les axes de recherche futurs sont proposés."
"en" => "Many papers were dedicated to database conceptual design. This paper is concerned with conceptual design of datawarehouses and multidimensional systems. We describe and compare three approaches: - the method proposed by Kimball based on the star model, - the method proposed by Kimball based on the flake model, - the MAP method proposed by Akoka and Prat based on the multidimensional model. The three approaches are illustrated through the same example consisting of a decisional system which aims at evaluating companies for acquisition. Based on EER conceptual modeling, the last method allows the designer to distinguish strictly between conceptual and logical designs. Kimball's methods offer a rapid way to generate the metadata of the datawarehouse. Further research is discussed."

In this paper, we develop a framework characterizing backsourcing as an organizational innovation. We offer a set of propositions on the adoption of a backsourcing strategy. This framework recognizes the role that social context and organizational action plan play in the adoption of IS/IT backsourcing. It serves to clarify why organizations backsource and to understand the antecedent of backsourcing, especially the outsourcing decision. Several hypotheses illustrate the backsourcing decision. The framework has value for both researchers and practitioners."

L'objectif de cet article est double. D'une part, nous présentons les principaux concepts et principes qui gouvernent le nouveau paradigme de logiciel de communauté. D'autre part, nous proposons un modèle permettant de prédire l?intention d'une organisation appartenant au monde de l'éducation à adopter ce nouveau dispositif. Ce modèle résulte d'une analyse de la littérature liée à l' «open source» ainsi que celle relative à l'«e-learning ». Nous construisons des hypothèses sur la base des résultats de recherche dans ces domaines. Une étude pilote a été menée pour valider ce modèle et ses variables. Cette étude confirme la pertinence des variables et la vraisemblance des hypothèses énoncées. La recherche future permettra de vérifier les hypothèses du modèle sur une base plus large notamment en termes de taille et de variétés d'organisations à inclure dans l'échantillon étudié."
"en" => "Open source software is now widely developed and used. In this paper, we describe a new paradigm based on a similar concept, the community source. We describe the main principles guiding the community source project. Then we propose a research model intending to predict the adoption of a community source project by education institutions and more specifically by higher education universities . Our model results from a tight combination of adoption models related to the open source phenomenon and those considering the e-learning domain. A pilot study has been conducted confirming the main hypotheses of our model. Future research will include a wide field study allowing us to verify the model hypotheses."

La première enquête a été menée au printemps 1997 et la seconde au printemps 1998. Cette enquête est fondée à la fois sur l'étude directe des sites WEB et sur un questionnaire. L'étude des entreprises ayant déjà une vitrine et/une boutique électronique nous permet d'en tirer quelques conclusions générales. Nous montrons en particulier que les objectifs principaux des entreprises ayant opté pour le commerce électronique sont : - la facilité d'accès de la clientèle aux produits français, vingt quatre heures sur vingt quatre, - l'élargissement de la clientèle française. Les entreprises estiment que ces objectifs sont en général atteints bien qu'ils ne soient pas quantifiés. Nous concluons que les entreprises françaises commerçant sur Internet sont divisées en trois groupes selon leurs précédentes expériences sur Minitel."

The first survey was conducted during spring 1997 and the second one was renewed in spring 1998. It is based both on a direct study of the WEB sites and on a questionnaire. The study of the firms, which already have an electronic shop, leads us to some general conclusions. We show in particular that the main objectives for the firms, which have decided on electronic commerce, are mainly: - facilitating customer access to products from home, twenty-four hours a day, - increasing the number of French customers.These firms estimate that these objectives are usually reached even if they are not quantified. Our conclusions are that French firms selling on the Internet are grouped into three categories according to their previous experience with the Minitel."

L'approche conjugue l'exploration de trois sources: les spécifications DDL, les spécifications DML et les données. A l'aide d'heuristiques, on découvre la sémantique de la base de données, notamment les liens d'inclusion et les contraintes d'existence. Un algorithme dérive automatiquement les liens d'héritage. Des heuristiques sont aussi proposées pour interpréter la sémantique des valeurs nulles ainsi que des valeurs par défaut. Le processus s'insère dans l'approche de rétro-conception MeRCI fondée sur l'inversion du cycle de vie du processus de conception."
"en" => "This paper proposes to combine a heuristic technique and an algorithmic one to provide a method to reverse engineer the generalization/specialization links hidden in a relational database. The heuristic phase combines the exploration of three sources: DDL specifications, DML specifications and data to provide information, such as inclusion links and existence constraints. This information is then used by the algorithm to derive automatically the inheritance links. Heuristics are also provided to detect the semantics of null values and default values when used for null values. The whole process is inserted into the MeRCI reverse engineering framework based on the inversion of the life cycle design process."

It is combined with natural language techniques such as Fillmore's semantic cases and Sowa's conceptual graphs, that can be found in semantic dictionaries."

Cette enquête est fondée à la fois sur l'étude directe des sites WEB et sur un questionnaire. L'étude des entreprises ayant déjà une vitrine et/une boutique électronique nous permet d'en tirer quelques conclusions générales. Nous montrons en particulier que les objectifs principaux des entreprises ayant opté pour le commerce électronique sont : - l'élargissement de la clientèle, spécialement à l'étranger, avec un investissement minimal, - la diffusion plus large d'une information plus riche pour les produits et/ou services de l'entreprise. Les entreprises estiment que ces objectifs sont en général atteints bien qu'ils ne soient pas quantifiés. Etant donné la croissance de ce marché, l'article conclut sur l'utilité de réitérer cette enquête dans les mois qui viennent pour suivre les évolutions de ce marché et en détecter les invariants."

It was based both on a direct study of the WEB sites and on a questionnaire. The study of the firms which already have a display and/or an electronic store leads us to some general conclusions. We show in particular that the main objectives for the firms which have chosen electronic commerce are mainly : (1) increasing the number of customers, especially abroad, with a minimal investment, (2) providing a wider circulation of a richer information for the products and/or services of the firm. The firms estimate that these objectives are usually reached even if they are not quantified. Considering this growing market, the article draws the conclusion upon the interest of repeating this survey during the following months in order to keep up with the evolutions of this market. and detect its invariants."

"en" => "Frequently the behaviour of an information system is functionally correct, but it does not meet some quality criteria, such as completeness, consistency, and usability. One way to enhance the capability of an information system is to consider its conceptual model quality as well as its functional behaviour. Conceptual model quality can be defined as a set of perceivable characteristics expressed with quantifiable parameters that may be objective and/or subjective. The aim of this empirical investigation is to evaluate and compare perceived and measured quality of different conceptual model versions of the same universe of discourse. This paper describes: a) a set of metrics (clarity, simplicity, expressiveness, minimality) applied to different versions of ER conceptual schemas, b) a framework enabling a comprehensive comparison of the conceptual schemas, c) an experimentation leading to the evaluation of the same schemas by information system (IS) stakeholders such as designers, end-users, and students, d) a comparison of the objective and subjective evaluations based on a sample of about 120 observations using different statistical methods. First results indicate that there exists a strong relationship between perceived and measured quality. A second result reveals a significant difference between groups of respondents in their ways to perceive conceptual schemas quality. Based on our experiment, we are able to identify quality criteria relevant to different groups of stakeholders, depending on several dimensions, such as their professional experience, and/or their specialization degree."

En génie logiciel, un patron est une solution réutilisable fondée sur la capitalisation de pratiques bien connues et validées. Le rôle d'un patron est d'accélérer le processus de développement du système d'information. Cet article propose un concept de patron de qualité. Ce dernier est utilisé pour structurer des solutions prédéfinies d'évaluation de la qualité des modèles conceptuels. La seconde contribution est liée à la combinaison de deux concepts : les patrons de qualité et les patrons de conception en un processus à trois étapes visant à i) guider l'évaluation de la qualité ii) aider les concepteurs à améliorer leur modèle conceptuel au moyen de patrons de conception, iii) évaluer l'amélioration par mesure de la qualité du résultat."

The role of a pattern is to speed up development process. The aim of this paper is twofold: it first proposes a concept of quality pattern. The latter is used to structure and to package predefined solutions for evaluation of conceptual modelling quality. The second contribution is related to the combination of two concepts, namely quality patterns and design patterns in a three-step process aiming at i) guiding the quality evaluation by the use of quality patterns, ii) helping designers improve conceptual models using design patterns, iii) evaluating the improvement by quality measurement."

"fr" => "Il est fréquent que le comportement d'un système d'information (SI) soit fonctionnellement correct, mais qu'il ne respecte pas certains critères de qualité, comme la complétude, la cohérence ou l'utilisabilité. Une façon de renforcer la capacité d'un SI est de considérer la qualité de son modèle conceptuel. Celle-ci peut être définie au moyen d'un ensemble de caractéristiques exprimées avec des paramètres quantifiables. Le but de cette recherche empirique est de faire évaluer la qualité des différents modèles conceptuels potentiels pour un univers du discours par des parties prenantes différentes. Cet article décrit : a) un ensemble de facteurs de qualité (clarté, simplicité, expressivité, minimalité) appliqués à différentes versions de schémas conceptuels entité-relation (ER), b) une approche permettant une expérimentation conduisant à l'évaluation des mêmes schémas par différentes parties prenantes : des concepteurs, des utilisateurs finaux, des étudiants. L'échantillon est constitué d'environ 120 observations. Ces données sont analysées au moyen de plusieurs méthodes statistiques. Les premiers résultats indiquent qu'il existe une indépendance forte entre les parties prenantes et les facteurs de qualité utilisés. De plus, l'analyse statistique révèle une différence significative entre les groupes de répondants dans leur façon de percevoir la qualité des schémas conceptuels. Sur la base de cette recherche expérimentale, nous sommes en mesure d'identifier des facteurs de qualité pertinents par groupe de parties prenantes, selon plusieurs dimensions : expérience professionnelle, degré de spécialisation, etc."
"en" => "Frequently the behaviour of an information system is functionally correct, but it does not meet some quality criteria, such as completeness, consistency, and usability. One way to enhance the capability of an information system is to consider its conceptual model quality as well as its functional behaviour. Conceptual model quality can be defined as a set of perceivable characteristics expressed with quantifiable parameters that may be objective and/or subjective. The aim of this empirical investigation is to evaluate and compare perceived and measured quality of different conceptual model versions of the same universe of discourse. This paper describes: a) a set of metrics (clarity, simplicity, expressiveness, minimality) applied to different versions of ER conceptual schemas, b) a framework enabling a comprehensive comparison of the conceptual schemas, c) an experimentation leading to the evaluation of the same schemas by information system (IS) stakeholders such as designers, end-users, and students, d) a comparison of the objective and subjective evaluations based on a sample of about 120 observations using different statistical methods. First results indicate that there exists a strong relationship between perceived and measured quality. A second result reveals a significant difference between groups of respondents in their ways to perceive conceptual schemas quality. Based on our experiment, we are able to identify quality criteria relevant to different groups of stakeholders, depending on several dimensions, such as their professional experience, and/or their specialization degree."

Cependant, les modèles conceptuels multidimensionnels actuels représentent imparfaitement les connaissances d'agrégation.

In order to account for the characteristics of this knowledge, we propose to represent it with objects (UML class diagrams) and rules in Production Rule Representation (PRR) language.
